Solve the equation.
7h-5(3h-8)=-72

Solve The Equation.7h-5(3h-8)=-72

Answers

Answer 1

Answer:

4 hours

Step-by-step explanation:

7h - 5(3h - 8) = -72  Distribute the -5

7h - 5(3h )(-5)(-8) = -72  A negative times a negative is a positive

7h - 15h + 40 = -72  Combine like terms

-8h + 40 = -72  Subtract 40 from both sides

-8h +40 - 40 = -72 - 40

-8h = -32  Divide both sides by -8

[tex]\frac{-8h}{-8}[/tex] = [tex]\frac{-32}{-8}[/tex]

h = 4

D. 20%
E. 75%
Please show work and I will make brainlist.

Answers

Answer:

B

Step-by-step explanation:

x% of 6 = 5.25

[tex]\frac{x}{100}[/tex] x 6 = 5.25

[tex]\frac{(5.25)(100)}{6}[/tex] = x

x = 87.5 %

discount = 100 - 87.5 %

= 12.5 %

5.25/6=x/100
Cross multiply
6x=525
525/6
87.5% is how much 5.25 is when compared to 6
100-87.5
12.5%
The answer is 12.5%

Kyle fills the candle mold with liquid candle wax. If
the candle has a volume of 99 cubic inches, what is the
width of the mold?

Answers

Answer:

w = 3 inches

Step-by-step explanation:

Given that,

The volume of the candle, V = 99 cubic inches

Length, l = 11 inches

Breadth, b = 3 inches

We need to find the width of the candle. The candle is in the form of a cuboid. The volume of cuboidal shape is given by :

[tex]V=lwh[/tex]

Put all the values,

[tex]w=\dfrac{V}{lb}\\\\w=\dfrac{99}{11\times 3}\\\\w=3\ inches[/tex]

So, the width of the mold is 3 inches.

X=12 because the ABC triangle is doubled the values

The similarity ratio of two similar triangles is equal to the ratio of their corresponding sides :

Similarity ratio = BA / GF = BC / GH = CA / HF

Similarity ratio = 18 / 9 = 14 / 7 = x / 6

x / 6 = 2

multiple sides by 6

6 × x / 6 = 6 × 2

simplification

x = 12
