Answer:
QR = 82.38 to nearest hundredth.
Step-by-step explanation:
As they are similar corresponding sides are in the same ratio.
So MN / QR = LM / QR
13/51 = 21/ QR
`3QR = 51*21
QR = 51*21/13
QR = 82.38
Answer:
12 chocolates
Step-by-step explanation:
Represent the original number of chocolates by c.
Then (1/4)(2/3)c = 2
Solving this for c, we multiply both sides by 4: (2/3)c = 8
and then multiply both sides by (3/2): c = (3/2)(8) = 12
Originally the box contained 12 chocolates.
1. 12-9×3×4+3=-93
2.3+4×3×9-12=99
3. 12-9+3×9×3×4=327
