C is the answer. Congruent is just a synonym of similar therefore C is the answer.
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
A. Bc a negative times a negative would be positive
C. Bc it would equal 0 and zero is not negative.
1*-7=-7 it wants a negative value so times it by one keeps it negative and same with if it is Multiplied by 7
Since both y’s are negative you can combine them to make -6y=1 then you divide -6 on each Side to get y=6
First you'll have to bring the equation in form y = mx + b.
4y = -x - 32
y = -1/4 x - 8
So the slope is -1/4 and y-intercept is -8
Hope this helps :)
