Answer:
Step-by-step explanation:
12 ÷ 12 ÷ 4 × 3^2
Exponential is treated first
= 12 ÷ 12 ÷ 4 × 9
Division follows
= 1 ÷ 4 × 9
= 1/4 × 9
= 9/4
= 2 1/4
Answer:
Step-by-step explanation:
The 2 figures are similar so corresponding sides are in the same ratio.
The factor is the value that you have to multiply a side in the first rectangle to get the corresponding side in the second rectangle.
12 ----> 9
So:
12 * f = 9 where f is the factor
f = 9/12 = 3/4.

Answer:
x = 10
y = 50
Step-by-step explanation:
9x - 70 = x + 10
8x - 70 = 10
8x = 80
x = 10
3y - 60 = 90
3y = 150
y = 50
