Hello! :)
Let one number be equal to x.
Since the other is 12 more, we can express this as x + 12.
Write an expression showing the sum of these two numbers equal to 40:
x + (x + 12) = 40
Combine like terms:
2x + 12 = 40
Subtract 12 from both sides:
2x = 28
Divide both sides by 2:
x = 14
This is the value of one of the numbers. Since the other number is "x + 12", we can solve for this value:
14 + 12 = 26.
The two numbers are 14 and 26.
It is 35 degrees a piece. Check the previous answer between both of us for clarification.
Hope I helped!
Good luck!

Answer: 8/9
Step-by-step explanation:
3x/7 = 8/21, find x
Step 1: cross multiply the equation
3x × 21 = 8×7
63x = 56
Divide both sides by 63; retain in fraction.
x = 56/ 63
x = 8/9
