Question

How do I do these step by step thank u

Answer 1

1) 24

2) 25

Explanation:

Given:

2a + 3b = 8

4x + 10y = 50

.

1)

`(6a + 9b)/(2a + 3b) = (3(2a + 3b))/(2a + 3b) = 3`

Since the second expression is 3 times greater then the previous one, the product will also be 3 times greater:

6a + 9b = 3 × 8 = 24

.

2)

`(2x + 5y)/(4x + 10y) = (2x + 5y)/(2(2x + 5y)) = (1)/(2) = 0.5`

The second expression's value is two times smaller than the first one's, so the product will also be two times smaller:

2x + 5y = 0,5 × 50 = 25
