Answer:
m = -5 + 2b
Step-by-step explanation:
2b - m = 5
<u>-2b -2b</u>
<u>-m</u> = <u>5 - 2b</u>
-1 -1
5 ÷ -1 = 5
-2b ÷ -1 = 2b
m = -5 + 2b
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7

Step-by-step explanation:
31=2y-5
Add 5 on both -5+5 which cancels out and 31+5 which is 36 and then divide 36 by 2 which equals to 18.
So y=18 hope this helped (':
