Answer:
Step-by-step explanation:
Use proportions to solve.
Corresponding sides have same ratio.
<u>Question 1</u>
- (6x + 3)/17 = (8x - 1)/21
- 21(6x + 3) = 17(8x - 1)
- 126x + 63 = 136x - 17
- 10x = 80
- x = 8
<u>Question 2</u>
- (x + 8)/21 = 32/28
- x + 8 = 21*8/7
- x + 8 = 24
- x = 24 - 8
- x = 16
Answer:
2/5 g/cm
Step-by-step explanation:
When you want to know "A per B", divide the given quantity of A by the corresponding quantity of B. ("Per" essentially means "divided by".)
It can be convenient to choose table values that make the division easy:
12 g/(30 cm) = 4/10 g/cm = 0.4 g/cm
20 g/(50 cm) = 2/5 g/cm . . . . . . . . . . . . . same as 0.4 g/cm
