2x+b=w,for x i need to know what this answer is

Answers

Answer 1

Answer:

Let's take this step by step:

2x+b=w

2x+b-b=w-b (the basics to what we are trying to do is to get x alone so that it equals whatever is on the other side of the equation.)

2x=w-b(now that we got rid of the b on the left side of the equation by canceling it out, we have to subtract by b on the other side of the equation as well)

2x divided by 2=w-b/2 (For our final step x is being mulitplied by 2 so what we can do to get x alone is canel out the multiplication by dividing by 2. What this does is it leaves x alone showing us what x equals)

x=w-b/2

A family bought a total of 16 adult and child tickets to a magic show. Adult tickets are $10.50 each and child tickets are $7.50 each. The family paid a total of $141. How many of adult tickets, a, and child tickets, c, did they buy?

Answers

9514 1404 393

Answer:

7 adult tickets9 child tickets

Step-by-step explanation:

Using the variables defined in the problem statement, we can write the equations ...

a + c = 16 . . . . . . . . . . . . number of tickets bought

10.50a +7.50c = 141 . . . cost of tickets bought

Substituting for c in the second equation, we get ...

10.50a +7.50(16 -a) = 141

3.00a +120 = 141 . . . . . . . . simplify

3a = 21 . . . . . . . . . . . subtract 120

a = 7 . . . . . . . . divide by 3

16 -a = c = 9 . . . . . . . find the number of child tickets

They bought 7 adult tickets and 9 child tickets.

_____

If you examine the solution, you see that the number of adult tickets (the higher priced item) is the quotient of the difference between the actual expenditure (141) and the amount that would have been spent on all child tickets (16×7.50=120), and the difference in ticket prices (10.50-7.50=3.00). Knowing this, you can often work problems of this kind in your head.

Find the missing value in the follwing equivalent ratios: StartFraction 1 inch Over 2.54 centimeters EndFraction = StartFraction 4.5 inches Over question mark centimeters EndFraction To find how many centimeters are in 4.5 inches, you should 2.54 by 4.5 4.5 inches = centimeters

Answers

Answer:

11.43 centimeters

Step-by-step explanation:

Given the equivalent ratios :

StartFraction 1 inch Over 2.54 centimeters EndFraction = StartFraction 4.5 inches Over question mark

1 inch / 2.54 cm = 4.5 inch /?

Let missing value = x

1 inch / 2.54 cm = 4.5 inch /x

Cross multiply

1 inch * x = 2.54 * 4.5

1 inch * x = 11.43

x = 11.43 cm

Hence, missing value = 11.43 centimeters

Answer:

B, 2x^2 - 4x + 8

Step-by-step explanation:

Given an area of 4x^2 - 8x + 16, and a length of 2, we can use the area formula of length, and width to find the area:

Length × Width = Area

Given these values, rearrange the formula to find the width:

Width = Area / Length

Then just substitute the values, and

simplify the expression:

Width = (4x^2 - 8x + 16) / 2

Width = 2x^2 - 4x + 8

(Answer to get brainliest)

Answers

Answer:

17in, 49in, 35in

Step-by-step explanation:

I did this in my RSM homwork and it is correct.

First, I added the two inches shorter to the 101, then subtracted 1 longer and got 102.

then divide 102 by how many second lengths, 6. so 102 ÷ 6 = 17

17 is the second length.

3x17-2=49 (another length)

2x17+1=35 (last length)

and there is your answer!

First side : 49

Second side : 17

Third side : 35

What is the perimeter of a triangle?

If triangle has sides a, b, c , then the perimeter of that triangle will be P= a +b +c.

Now, according to the question

Let second side be (b) = x unit

then, First side will be (a)= 3x-2 unit

and Third side will be (c)= 2x + 1 unit

since , perimeter is 101

P = a + b + c

x + 3x -2 + 2x + 1 = 101

6x - 1 = 101

x= 17

hence , b = 17 unit

a= 3*17 - 2 =49 unit

c = 2*17 +1 = 35 unit

A computer store pays sales associates $10 per hour

and managers $15 per hour. If the total hours
worked by the sales associates is 100 and the total

hours worked by managers is 50, how much will the

store pay in wages?

Answers

Answer:

They pay a total of $1750.

Step-by-step explanation:

You multiply the hours by the pay per hour SO,

Managers= $15 multiplied by the 50 hours they worked ($15 * 50hrs.) and get "$750"

Associates= $10 multipled by 100 hours ($10 * 100) and get "$1000"

Add the total sums ($750 + $1000) and get a total of $1750

During a special sale, all video games cost $26 and all movies cost $14. Derrick plans to spend some or all of his $220 in birthday money on these movies and video games. Let "x" represet the number of games Derrick can buy and "y" represent the number of movies he can buy. Write the inequality that describes this situation in standard form.

Answers

Answer:

[tex]13x+7y\leq 110[/tex]

Step-by-step explanation:

Let "x" represents the number of games Derrick can buy and "y" represents the number of movies he can buy.

Cost of all video games = $26

Cost of all movies cost = $14

Total amount with Derrick = $220

So,

cost of [tex]x[/tex] video games + cost of [tex]y[/tex] movies [tex]\leq[/tex] 220

Therefore, the inequality is [tex]26x+14y\leq 220[/tex]

Divide this inequality by 2

hope this helps!!

Answer:

3.4X10^-4

remove the zeros and add a decimal point after the first number eg.

0.00034 --> 34 --> 3.4

then add a x 10 eg.

3.4x10

then add a power- if the number is larger than 1 count the amount of zeros and add that as your power eg.

3400 -> 34 -> 3.4 -> 3.4x10^2

If the number is lower than one use a negative power eg.

0.00034 -> 34 -> 3.4 -> 3.4x10^-4

Write the equation of the line through the points (4, 5) and (12, 9)

Answers

Answer:

y = 1/2x + 3

Step-by-step explanation:

y2 - y1 / x2 - x1

9 - 5 / 12 - 4 = 4/8 = 1/2

y = mx+b

slope/m = 1/2

y = 1/2x + b

5 = 1/2(4) + b

5 = 2 + b

3 = b

y = 1/2x + 3

The equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6

From the question,

We are to determine the equation of the line passing through the points (4, 5) and (12, 9)

Using the formula,

[tex]\frac{y-y_{1} }{x-x_{1}} = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

From the given information

x₁ = 4

y₁ = 5

x₂ = 12

y₂ = 9

Putting the parameters into the formula, we get

[tex]\frac{y-5}{x-4} =\frac{9-5}{12-4}[/tex]

Then,

[tex]\frac{y-5}{x-4} =\frac{4}{8}[/tex]

[tex]\frac{y-5}{x-4} =\frac{1}{2}[/tex]

Then,

[tex]x - 4 = 2(y-5)[/tex]

[tex]x - 4 = 2y-10[/tex]

[tex]x -2y = -10 + 4[/tex]

[tex]x -2y = -6[/tex]

Hence, the equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6

154+2x=360

Step-by-step explanation:

Since the opposite angles are the same you add them together getting 154. You now have two unknown angles that are congruent which is expressed as 2x, and since a four sided shape always has an interior angle of 360 you set it equal. This gives you 154+2x=360.

Answer: It is the last one

154 + 2x = 360

Step-by-step explanation:

x= 103

154 + 2(103)= 360
