What is the result if 75 is added to 175, and then is divided by 5?

Step-by-step explanation:

75% of x plus 75 = x

0.75x + 75 = x

Bring the variable terms to the left side of the equation by subtracting x from both sides.

-0.25x + 75 = 0

Bring the constant terms to the right side by subtracting 75 from both sides.

-0.25x = -75

Divide both sides by -0.25

x = 300

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the height of the surface increases from the center out to the sides of the road

it is c!
