This question states that Lake Lopez began at a depth of 515 inches, then increased by 82 inches, then decreased by 119 inches. To model this, we will use addition for the increase and subtraction for the decrease; this will signify a positive/negative change in the depth. This can be modeled by the expression below:
515 + 82 - 119
597 - 119
478
Therefore, the water depth at the end of the summer was 478 inches.
Hope this helps!

Answer:
-11.7
Step-by-step explanation:
3.3+5(-7 + 4)
we apply distributive property
3.3+5*(-7) + 5*(4)
we know:
+ * - = -
+ * + = +
so we have:
3.3 -35 + 20
3.3 - 15
-11.7
Answer:
w = 7 7/8
Step-by-step explanation:
w + 1/8 = 8
First, subtract 1/8 from both sides of the equation
w + 1/8 = 8
- 1/8 - 1/8
w = 7 7/8
I got it as 4 when calculating all have the same number which is 133
