Step-by-step explanation:
2(9n-1)+7(n+6)=-60
18n - 9 + 7n + 42 = -60
25n + 33 = -60
25n = -93
n = -3.72
11(4-6y)+5(13y+1)=9
44 - 66y + 65y + 5 = 9
-y + 49 = 9
-y = -40
y = 40
5 - 8 would be a negative answer
think of it as a bank account if you $5 in the account and you take away $8, how much would you have after? $-3 so your answer would be -3
and same with -5-(-3)
this would be -2
Answer:
y=54
Step-by-step explanation:
Answer:
512:27
Step-by-step explanation:
We just cube the edge length ratio since a pyramid is a 3-dimensional figure and volume is 3-dimensional:
8:3 -> 8^3:3^3 -> 512:27
Therefore, the correct answer is 512:27
Answer:
D.
Step by step explanation:
First of all we will convert our given time from minutes to hour by dividing 35 by 60.
Let us find speed of dog during walk.
Dividing a number by a fraction is same as multiplying the number by the reciprocal of the fraction.
Therefore, speed of dog is and option D is the correct choice.
