Answer 1

Answer:

B)

The given ratio is 3:5

Let the numbers be 3x and 5x

Their difference is 10

That is,

5x - 3x = 10

2x = 10

x = 5

Smaller number = 3x

= $3 \times 5$

= 15

C)

Subtract the numbers

2x + 1 − 3x − 7

2x + 1 - 3x - 7

2x − 6 − 3x

Combine like terms

2x − 6 − 3x

-x - 6

Therefore your solution,

-x-6.

Hope it helps mate! I'm so sorry I forgot to answer the second answer so I had to edit it.
