If you add 7 minutes to 7 minutes it equals 14, and 30 sec plus 30 seconds is 1 minute. That makes it the full 15 minutes which would equal 2 miles ran in total by Peter.

Solve for g gg. Give an exact answer. 10 ( 0.4 + 0.5 g ) = 4 g 10(0.4+0.5g)=4g10, left parenthesis, 0, point, 4, plus, 0, point,

kirill115 [55]

Answer:

the value of g is -4

Step-by-step explanation:

$10 ( 0.4 + 0.5 g ) = 4 g$

Our aim is to solve for g

multiply 10 inside the parenthesis

$4+5g = 4g$

Now combine like terms

Subtract 5g from both sides

$4+5g-5g= 4g-5g$

$4=-g$

Divide both sides by -1

$g=-4$

Sari drives 55 miles per hour. Which equation shows the proportional relationship between hours (h) and miles (m)?

Finger [1]

Answer:

$m=55h$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

m ----> the distance in miles (y-coordinate)

h ----> the time in hours (x-coordinate)

In this problem the constant of proportionality k is given and is equal to

$k=55\ \frac{miles}{hour}$ ----> the speed

substitute

$m=55h$

Evan was broke didn't he got his weekly allowance but because he has a hard time saving money he spent half his weekly allowance

grin007 [14]

Answer:

$16

Step-by-step explanation:

Let his weekly allowance = x

Amount spent playing golf = x / 2

Amount earned for cleaning car = $4

Final amount at hand = $12

Mathematically ;

x/2 + 4 = 12

x/2 = 12 - 4

x/2 = 8

x = 2 * 8

x = $16

Weekly allowance = $16
