Hi There!
Answer:
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 :)
Answer:
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
[tex]\frac{x + 5}{2} = 36[/tex]
This can be rewritten as:
[tex]\frac{1}{2} (x + 5) = 36[/tex]
The answer is C) [tex]\frac{1}{2}(x + 5) = 36[/tex]
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
