42.5p=c

You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.

M is representing the amount of money each person paid

(M)10=425
M=425/10
M=42.50 <- since it’s about money

Each person paid $42.50

The cost for 15 people is $637.50.

42.5p=c
42.5(15)=637.5

Answer:

x = 12

Step-by-step explanation:

$\frac{1}{2}$ x + 3 = $\frac{2}{3}$ x + 1

multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions

3x + 18 = 4x + 6 ( subtract 3x from both sides )

18 = x + 6 ( subtract 6 from both sides )

Solve for x.<br><br> −5(x−4)=−30<br><br> Enter your answer in the box.

saveliy_v [14]

First divide both sides by - 5,

$x - 4 = 6$

Move the constant to the right side of the equation and change its sign (-4 => +4)

$x = 6 + 4$

Add the numbers,

$x = 10$
