Answer:
The answer is
→ [tex]x=-8[/tex]
Step-by-step explanation:
Given: [tex]\frac{-72}{x} = 9[/tex]
Solve:[tex]\frac{-72}{x} = 9[/tex]
Step 1: Multiply all terms by the same value to eliminate fraction denominators.
[tex]\frac{-72}{x} = 9[/tex]
⇒ [tex]x * \frac{-72}{x} = x * 9[/tex]
Step 2: Cancel multiplied terms that are in the denominator.
[tex]x * \frac{-72}{x} = x * 9[/tex]
⇒ [tex]-72 = x * 9[/tex]
Step 3: Re-order terms so constants are on the left.
[tex]-72 = x * 9[/tex]
⇒ [tex]-72 = 9x[/tex]
Step 4: Divide both sides by the same factor.
[tex]-72 = 9x[/tex]
⇒ [tex]\frac{-72}{9} = \frac{9x}{9}[/tex]
Step 5: Simplify.
Divide the numbers.[tex]\frac{-72}{9} = \frac{9x}{9}[/tex]
⇒ [tex]-8 = \frac{9x}{9}[/tex]
Cancel terms that are in both the numerator and denominator.[tex]-8 = \frac{9x}{9}[/tex]
⇒ [tex]-8 = x[/tex]
Move the variable to the left.[tex]-8x = x[/tex]
⇒ [tex]x = -8[/tex]
Hence, [tex]x = -8[/tex] is your answer.

Answer: The first option
Explanation:What we know:
1 mile is equal to 5,280 feetThe length of the fence is 1/4 mileThe width of the fence is 1/8 mileHow to solve:
By finding the perimeter of the fence in feet, we can check that value against the 4 proportion options listed in the problem. Whichever is true will be the correct answer.
Process:Perimeter - in feet
Where P is perimeter in miles, x is perimeter in feet, w is width in miles, and L is length in miles.
Set up equation P = 2w + 2L
Substitute P = 2(1/8) + 2(1/4)
Simplify P = 2/8 + 2/4
Common denominator P = 1/4 + 2/4
Simplify P = 3/4 mi.
Translate x = (3/4)*5280
Simplify x = 3960 ft.
For the following: Where m represents the mile unit, f represents the foot unit, and x represents the number of feet of fencing.
First option
Set up equation (3/4)m/x = m/5280f
Equal variables 16[(3/4)m/x) = 12[m/5280f]
Simplify 12m/16x = 12m/63360f
Remove miles 16x = 63360f
Isolate x variable /16 /16
Solution x = 3960 ft.
Second Option
Set up equation (3/8)m/x = m/5280f
Equal variables 64[(3/8)m/x] = 24[m/5280f]
Simplify 24m/64x = 24m/126720f
Remove miles 64x = 126720f
Isolate x variable /64 /64
Solution x = 1980 ft.
Third Option
Set up equation x/(3/4)f = m/5280f
Equal variables 7040[x/(3/4)f] = m/5280f
Simplify 7040x/5280f = m/5280f
Remove feet 7040x = m
Translate 7040x = 5280f
Isolate x variable /7040 /7040
Solution x = (3/4)f
Fourth Option
Set up equation x/(3/8)f = m/5280f
Equal variables 14080[x/(3/8)f] = m/5280f
Simplify 14080x/5280f = m/5280f
Remove feet 14080x = m
Translate 14080x = 5280f
Isolate x variable /14080 /14080
Solution x = 3/8f
Answer: The first proportionCheck:
If the perimeter of the fence, in feet, is the first option, then when
x = 3960, the number of miles and feet should be equal. Let's test this.
(3/4)m/x = 1
(3/4)m/3960f = 1
(3/4)(5280f)/3960f = 1
3960f/3960f = 1
1 = 1
Therefore, option 1 is correct.

Find the unit rate and answer the question. Only put the number of hours in as your answer. (Your answer will look something like this... 325)
rate :
distance/time225/375 miles/hr======================
1 hours → 75 miles
? hours → (1125/75)
15 hoursIt takes her 15 hours to drive 1125 miles.
Answer:
15 hours
Step-by-step explanation:
Finding how much distance in 1 hour
⇒ Ceci = 225 miles = 3 hours
⇒ 225 miles = 3 hours
⇒ 225/3 miles = 3/3 hours
⇒ (25 x 9)/3 miles = 1 hour
⇒ (25 x 3) miles = 1 hour
⇒ 75 miles = 1 hour
Finding how much hours in 1125 miles
⇒ 75 miles = 1 hour
⇒ 75x miles = 1125 miles = x hours
⇒ 75x/75 = 1125/75
⇒ x = 15
⇒ 75(15) miles = 1125 miles = (15) hours
⇒ 1125 miles = (15) hours

Which is the best use for the converse of the Pythagorean theorem?
to show that all triangles have a right angle
to prove that a triangle is equilateral
to determine from the side lengths if a triangle is a right triangle
to find the length of an unknown side of a right triangle
Answer:
here you go
Step-by-step explanation:
The converse of the Pythagorean Theorem tells us that by comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.
To determine from the side lengths if a triangle is a right triangle. Therefore, the correct answer is option C.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
The converse of Pythagoras theorem states that “If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right angle triangle”.
By comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.
Therefore, option C is the correct answer.

Answer:
Radius: about 1.42 mm
Step-by-step explanation:
First, you divide the circumference (8.9) by 3.14, or π.
Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)
Diameter (2.83439490446) divided by 2 = radius (1.41719745223)
Now, you have to round to the nearest hundredth.
1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

what value of x makes the equation true 3/4x + 9 = 3
A. x = -8
B. x= -1/2
C. x = 1
D. x = 16
Answer:
[tex]\boxed{\sf{A. \quad X=-8}}[/tex]Step-by-step explanation:
To find the value of x, isolate it on one side of the equation.
3/4x+9=3
First, subtract by 9 from both sides.
3/4x+9-9=3-9
Solve.
3-9=-6
Rewrite the problem down.
3/4x=-6
Multiply by 4 from both sides.
4*3/4x=4(-6)
Solve.
3x=-24
Then, you divide by 3 from both sides.
3x/3=-24/3
Solve.
Divide these numbers goes from left to right.
-24/3=-8
x=-8
Therefore, the correct answer is A. x=-8.Variables and negative signs should appear in the answer.
I hope this helps you! Let me know if my answer is wrong or not.
Answer:
x = -8
Step-by-step explanation:
Subtract 9 both sides:
⇒ 3/4x + 9 = 3
⇒ 3/4x + 9 - 9 = 3 - 9
Simplify the L.H.S and the R.H.S:
⇒ 3/4x = -6
Use cross multiplication:
⇒ 3x/4 = -6
⇒ 3x = -6 × 4
Simplify the R.H.S:
⇒ 3x = -6 × 4
⇒ 3x = -24
Divide 3 both sides:
⇒ 3x/3 = -24/3
⇒ x = -8

Answer:
B. 150 ft
Step-by-step explanation:
Perimeter of a rectangle = 2(Length) + 2(Width)
Here, we are given the perimeter and width and we want to find the length
We can do so by plugging in what we are given into the perimeter formula and solving for length.
Perimeter = 2(Length) + 2(Width)
Perimeter = 450 and Width = 75
450 = 2(Length) + 2(75)
We now solve for length
==> simplify multiplication 2(75) = 150
450 = 2(Length) + 150
==> subtract 150 from both sides
300 = 2(Length)
==> divide both sides by 2
150 = Length
And we are done!
The answer is B 150ft

The volume of the prism shaped fish tank is: 408 in.³.
What is the Volume of a Prism?Volume of prism = base area × height of prism.
The fish tank is a prism having a height of 8 inches. To find its volume, find the base area, which is the area of the composite figrue given.
Thus:
Base area = area of rectangle + area of triangle = (length × width) + (1/2(base × height).
Given:
Length = 7 in.Width = 6 in.Base = 6 - 3 = 3 in.Height = 13 - 7 = 6 in.Therefore:
Base area = (7 × 6) + 1/2(3 × 6)
Base area = 51 in.²
Volume of the prism shaped fish tank = 51 × 8 = 408 in.³.

[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]
hope it helps you<3Answer:
H=5
Step-by-step explanation:
Simplifying the equation
We multiply 2(3H) =6H, so the equation is now 12-6H=-18
Isolating the Variables
Then, we subtract 12 from both sides, giving us -6H = -30
Finding H
Finally, we divide both sides by -6, so H= 5

A bakery sells 7 muffins for $3.50. What's the unit rate? $2/muffin $0.50/muffin $0.70/muffin $3.50/muffin
Answer:
$0.50/muffin
Step-by-step explanation:
To find the unit rate we have to find out how much 1 muffin costs:
To do this we can divide both sides by 7:
7÷7 for 3.50÷7
1 muffin for 0.50
Therefore our answer is $0.50/muffin
Answer:
$0.50 / muffin
Step-by-step explanation:
7 muffins for $3.50
To find the unit rate, we need to find what 1 muffin costs.
so
1 muffin = 3.5/7 = 0.5
$0.50 per muffin.
