If 3x + 7 = 12, what is the value of 6x - 5

5

Step-by-step explanation:

3x+7=12

3x=12-7

3x=5

x=5/3

6x-5=6(5/3)-5=30/3-5=10-5=5

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
