Answer:
Step-by-step explanation:
1 cm=10 km
8 cm=10×8=80 km
First, solve the parenthesis
Remember to follow PEMDAS, and the left-> right rule
12/3 = 4
4 x 2 = 8
8 + 3 = 11
11 - 7 = 4
Square the remaining number
4² = 4 x 4 = 16
16 is your answer
hope this helps
9 times 12 is 108. so 42/108=21/54
Answer:
8
Step-by-step explanation:
4³ ÷ 2³
= 64 ÷ 8
= 8
Answer:
∠B = 12°
∠C = 180 - 48° = 132° ( straight line angle = 180)
Sum of angles of a triangle = 180°
180 = ∠A + ∠B + ∠C
180 = ∠A + 12 + 132
180 - 144 = ∠A
∠A = 36°
option B
