The elevation of a fish is - 27 feet. the fish descends 32 feet, and then rises
14 feet. what is its new elevation?

-45 feet.

Step-by-step explanation:

That would be  - 27 - 32 + 14

= -59 + 14

= -45 feet.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
