To multiply decimals pretend there is no decimal for example
.165*74 = 12210; then however many digits (not counting zeros) is after the decimal added together (from both numbers) so 3 so 12.21 is the answer
Answer:
A and B: Isosceles (having two sides of equal length)
C: Equilateral (all sides are equal)
Answer:
8(15-m)
Step-by-step explanation:
By looking at the options, we can understand that the right one is 8(15-m), since we need to multiply the time by the number of question.
Also, we can check that result by arranging an equations usint the total time.
55 = 3m - 8(15-m)
55 = 3m - 120 + 8m
55 = 11m - 120
55 + 120 = 11m
175 = 11m
m = 175/11 = 15.91
55 = 3*15.91 - 8(15-15.91) = 47.73 - 120 + 127.28 = 55.01 ≈ 55
