Let
x--------> amount of starting rocks George had
we know that
------> equation that could be used to determine how many rocks George started with
Solve for x
Multiply by both sides
Subtract both sides
therefore
the answer Part a) is
The equation that could be used to determine how many rocks George started with is
the answer Part b) is
Hi There!
C) 1/2 (x+5) = 36
Step-by-step explanation:
Multiply 2 too both sides:
1/2 * 2 (x + 5) = 36 * 2
(x + 5) = 72
Subtract 5 too both sides:
x + 5 - 5 = 72 - 5
Simplify:
x = 67
Hope This Helps :)
C) 1/2 (x+5) = 36
George started with 70 rocks
Step-by-step explanation:
Given: After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks.
Let "x" be number of rocks that George started with.
After getting 5 new rocks.
He will have (x + 5) rocks.
George gave half of his rock collection to Susan.
(x + 5) /2 has given to Susan which is 36
Which can be written as
This can be rewritten as:
The answer is C)
To find the number of rocks George started with, we need to solve the above equation.
Multiply by both sides by 2, we get
(x + 2) = 2(36)
x + 2 = 72
Subtracting 2 from both sides, we get
x + 2 - 2 = 72 - 2
x = 70
So, George started with 70 rocks
