Answer:
Step-by-step explanation:
Given the equation:
1/5 × (x - 2) = 20
First step to solving the equation is
By multiplying both sides by the value of 5.
That will give,
x - 2 = 100
x = 100 + 2
= 102
Answer:
64 for number 1. Not sure on number 2 sorry.
Step-by-step explanation:
The equation would be: V = A2^(Y/3)
The basic form of an exponential equation is y = ab^x.
The a is the starting amount. In this problem, we don't know that, so we just leave it as a.
The b is the rate. In this case, we are doubling the volume so we times it by 2.
The x is the amount of years. Since it is every 3 years, we can divide the x by 3.
