Answer:
a) x= 42 , b) x=(16)/(9) , c) x=60
Step-by-step explanation:
a)
- Divide 48 by 8 - 48 / 8 = 6
- Multiply 6 by 7 - 6 x 7 = 42
- You get x = 42
b)
- Flip (9)/(2)…(i.e. reciprocal)
- Multiply 8 and 2 - 8 x 2 = 16
- You get x = (16)/(9)
c)
- Divide 80 by 4 - 80 / 4 = 20
- Multiply 20 by 3 - 20 x 3 = 60
- You get x = 60
