Answer 1

$5 + 4 = 9 \\ 156 \div 3 = 52 \\ 90 \times 5 = 450$

$12x = 132 \\ x = 132 \div 12 \\ x = 11$

5+4=9

156:3=52

90*5=450

12х=132

Х=132:12

Х=11

Answer 3

It looks like there might be some confusion in your calculations. Let's break down each part:

1. 5 + 4 = 9 (This is correct)
2. 156 ÷ 3 = 52 (156 divided by 3 equals 52, not 90)
3. 90 x 5 = 450 (90 multiplied by 5 equals 450, not 12)
4. 12x = 132 (This equation is incomplete and cannot be solved without knowing the value of 'x').
