-8x - 2y = -4

When y = -5x
-8x - 2(-5x) = -4
- 8x + 10x = -4
2x = -4
x = -4/2 = -2

-8x - 2y = -4 ; y = -5x
-8x - 2(-5x) = -4
-8x + 10x = -4
2x = -4
2x/2 = -4/2
x = -4/2 = -2/1 = -2
x = -2

The ratio of girls to boys in a running club was 3:5. There were 15 girls. How many total members were there in total?

AlexFokin [52]

Answer:

Step-by-step explanation:

The number of girls is represented by 3 parts of the ratio.

Divide number of girls by 3 to find value of one part of ratio.

$\frac{15}{3}$ = 5 ← value of 1 part of ratio, thus

5 parts = 5 × 5 = 25 ← number of boys

Total members = 15 + 25 = 40
