Answer: n divided by 43
Step-by-step explanation: You always take the last number of the equation and divide it by the answer and you should get the first number.
Answer:
Y
Step-by-step explanation:
The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130
In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110
X=3
Divide both sides of the equation by 2
X^3 =27
Write the number in exponential form with an exponent of 3
X^3=3^3
Since the exponents are the same, set the bases equal
X=3
