Answer:
a) 55 b)=21/32 c)x=6
Step-by-step explanation:
a)Follow the PEMDAS order of operations
Calculate within parentheses
(6 +3 x 2)
(6+6)
= 12
=51+ 12 ÷ 3
Multiply and divide (left to right)
12÷ 3=4
51 +4
Add and subtract (left to right)
51 + 4=55
B)
Follow the PEMDAS order of operations
29 – 8) ÷ 32
Calculate within parentheses
(29 – 8) =21
= 21 ÷32
Multiply and divide (left to right)
21 ÷32
=21/1× 1/32
=21/32
C)let the unknown be X
6+ 5× X- 16 = 20
Group like terms
5x +6- 16 = 20
Add/Subtract the numbers:
6- 16 = -10
5x - 10= 20
Add 10 to both sides
5x- 10 + 10 =20 + 10
Simplify
5x=30
Divide both sides by 5
5x/5=30/5
x=6
