Answer:
Dennis's score = 104
Explanation:
Let us represent:
Dennis's score = x
Amanda's score = y
Jorge's score = z
Three friends go bowling.
Dennis's score is 46 points greater than Amanda's score.
x = 46 + y
Amanda's score is 70 points less than Jorge's score.
y = z - 70
If Jorge's score is 128
z = 128
what is Dennis' score?
Step 1
we solve for y = Amanda's score
y = z - 70
z = 128
y = 128 - 70
y = 58
Step 2
We solve for Dennis's score
x = 46 + y
x = 46 + 58
x = 104
Dennis's score = 104
