1/2x+4=9 solve for x.. Help?
Answer:x=10
Step-by-step explanation:
Step 1: Subtract 4 from both sides.
Step 2: Multiply both sides by 2.
Answer: x=10
Step-by-step explanation:
1/2x+4=9
-4 -4
1/2x=5
multiply by 1/2 on each side
x=10

What is the simplified form of the expression 0.3 (4x - 4y)?
Answer:
1.2x-1.2y
Step-by-step explanation:
3. A teacher made a copy of a map. To make the map easier to see, the teacher enlarged the area of the map by 38%. Let d represent the area of the original map. The expression d + 0.38d is one way to represent the area of the new map. Write two expressions that represent the area of the new map.
Answer:
1.38d
Step-by-step explanation:
X =(5x - 10)
130°
Find x
Answer:
Step-by-step explanation:
5x-10 = 180-130
5x-10 = 50
5x = 60
x = 12°
On a coordinate plane, what is the distance between the point at (4, 7) and the point at
(-4, 7)?
Answer:

Answer:
rate: 24:2
unit rate: 12:1
Step-by-step explanation:
Given function:
24 inches in 2 feetto find the rate and unit rateWhat is the rate?:
24 inches would be the first digit and 2 feet would be the second one..
the rate would be 24:2..
What is the unit rate?:
unit rates would be the lowest form which means that you have to find a equivalent factor to find the unit rate..
24*2=12, 2*2=1
this also means 12:1
Therefore, the rate of 24 inches and 2 feet is 24:2 and the unit rate would be 12:1.
If a Point E lies between two points D and F such that DE = EF, then prove that DE = 1/2 DF. Explain by drawing the figure.
Answer:
Step-by-step explanation:
DE = EF
DF = DE + DF
= DE + DE
DF = 2DE
2DE = DF
DE = (1/2)DF

Answer:
a) 4³ = 4×4×4 = 64
so answer is 4³
b) (3²)⁶ = 3²×⁶
= 3¹²
so answer is 3¹²
c) 125 = 5³
(5⁴)⁷ = 5²⁸
= 5³ × 5²⁸
= 5³¹
Answer:
a, 4 the power of 3
b,3 the power of 12
c, 5 the power of 31
Step-by-step explanation:
a. prime factorization of 64 is 4^3
b. 2.6=12 so it became 3^12
c. prime factorization of 125 is 5^3 then 7.4 =28
so 5^3 . 5^28 = 5^31

How many times larger is 6*10^ 7 than 3*10^ 6 ?
Answer:
20
Step-by-step explanation:
step 1: Evaluate the expressions
6*10^7 = 60,000,000
3*10^6 = 3,000,000
step 2: Devide
60,000,000 / 3,000,000 = 20
so 60,000,000 is 20 times larger than 3,000,000
Your teacher might want you to use a different method, but I believe this is the simplest way. If you have any questions feel free to ask away
Answer:
20
Step-by-step explanation:
[tex] \dfrac{6 \times 10^7}{3 \times 10^6} = \dfrac{6}{3} \times 10^{7 - 6} = 2 \times 10^1 = 20 [/tex]

Reason 2:
-Division Property of Equality
-SAS Postulate
-AA Postulate
-Reflexive property of Congruence
-Given
-Vertical Angle Theorem
-SSS Postulate
-Prove
Answer:
Missing reasons:
1. Given (the ratios of corresponding sides)
2. Reflexive property of Congruence (same angle K)
3. SAS Postulate (two sides are similar and the included angle congruent)
The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 30 , P = 1260 . Work out the power when the speed is 25 m / s
Answer:
875 Watts
Step-by-step explanation:
Given that :
P α s²
P = ks²
Where k is the proportionality constant
When ; p = 1260 ; s = 30
1260 = k * 30²
1260 = 900k
k = 1260 / 900
k = 1.4
Value of p ; when s = 25
P = 1.4 * s²
P = 1.4 * 25²
P = 1.4 * 625
P = 875 watt

Find the area of the circle. Round your answer to the nearest hundredth.
2 cm
Answer:
12.57 if 2cm is the radius,
3.14 if 2cm is the diameter
Step-by-step explanation:
If the radius 2cm
A = πr^2 = π·2^2 ≈ 12.56
If the diameter 2cm
A= πr^2 = π·1^2 ≈ 3.14
Write an expression equivalent to 6 - 4(3 - 6m) + 12m that is the product of two factors. Show your work.
Answer: 6(6m - 1)
Step-by-step explanation:
6 - 4(3 - 6m) + 12m
= 6 -12 + 24m + 12m
= 36m - 6
= 6(6m - 1)
