Answer:
27 hours
Step-by-step explanation:
216/8=27
Answer:
3/7
Step-by-step explanation:
First, when dividing 6/7 by 2 you need to change the number 2 into a fraction. The number 2 as a fraction is 2/1. However, this is division so you need to reverse the fraction so it is 1/2 instead of 2/1. So, 6/7 x 1/2 = 6/14. You can simplify to get your the answer.

Answer:
95>=X <=100. More or equal to 95 or equal or less than 100.
Step-by-step explanation:
The Total of the first score is needed first
81+87+ 94+93=355
The total of this score
Let X be the 5TH score we are looking for
(355+ X)/5= 90
355+X= 450
X= 450-355
X= 95 the person needs to sore between 95 and 100 ( which is the highest possible score).
Answer:
y= -1/3x + 5
Step-by-step explanation:
Answer:
n= 21
c= 3x
Step-by-step explanation:
The expression is given as;
(3x⁷)⁴
Apply the brackets law of indices which states that :
If a term with a power is itself raised to a power then the powers are multiplied together
(xᵃ)ᵇ = xᵃˣᵇ
Applying the same;
(3x⁷)⁴ = 3x²¹
If 3x²¹ = c^n
Then n = 21
and
c= 3x
