Answer:
58
Step-by-step explanation:
1. let x be the unknown number
2. make an expression
x + 26/12 = 7/1
3. cross multiply
x +26 × 1 = x + 26
12 × 7 = 84
x + 26 = 84
4. move variables on one side and numbers on other side of the equal sign
x + 26 = 84
- 26 -26
x = 58
Answer:
d < 8
Step-by-step explanation:
Given
- 12 + 8d < 52 ( add 12 to both sides )
8d < 64 ( divide both sides by 8 )
d < 8
