Hello!
1. 8y = 48 => y = 48 : 8 => y = 6
2. q - 12 = 1 => q = 1 + 12 => q = 13
3. 18 = a/2 => a = 18 × 2 => a = 36
4. r/3 = 7 => r = 3 × 7 => r = 21
5. 11 = m - 4 => m = 11 + 4 => m = 15
Good luck! :)
Answer:
f=11
Step-by-step explanation:
If t=7, we can substitute it into the original equation:
f=(2)(7)-3
Simplify:
f=14-3
f=11

Let the two numbers be x and x + 40, then
x + x + 40 = 180
2x = 180 - 40 = 140
x = 140/2 = 70
Therefore, the measures of the two angles are 70° and 70 + 40 = 110°
