Answer:

u = 12

Step-by-step explanation:

4u - 8u - 15 = -63

Step 1: Combine 4u and -8u

-4u - 15 = -63

Step 2: Add 15 to both -15 and -63

-4u = -48

Step 3: Divide both -4u and -48 by -4

u = 12

365x + 125 = 250x + 175

maxonik [38]

First, set up the equation.
365x + 125 = 250x + 175

Second, combine like terms on the same side by subtracting 250x and 125 from both sides.

365x +125 = 250x + 175
-250x -125 -250x -125
__________________
115x = 50

Third, divide both sides by 115 to solve for x.

115x = 50
---- ----
115 115

Fourth, simplify.

x=50/115=10/23 or 0.435

Xelga [282]

Answer:

a) 35, b) 25, c) 60

Step-by-step explanation:

The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.

Number of boys: b

Number of girls: b + 10

Ratio of girls:boys is 7:5, so

$\frac{b+10}{b}=\frac{7}{5}$
