Answer:
2.64
Step-by-step explanation:
x² + 6= 13
x² = 13-6
x²= 7
x = square root of 7
x = 2.64
It is given in the question that
The gas tank of Tyrell's truck holds 19.8 gallons. when the tank empty, Tyrrell fills it with gas that costs $3.65 per gallon.
It means cost of one gallon of gas is $3.65 .
And the tank hold 19.8 gallon . So cost of 19.8 gallon is

Therefore about $72.27 it will cost to fill the tank .
(x+108) and (x+88) are supplementary angles. This means that they add to 180.
(x+108) + (x+88) = 180
Solve for x:
2x + 196 = 180
2x = -16
x = -8

4) A
5) E
Step-by-step explanation:
#4


Cross multiply the equation and you get:

Since
is the same thing as
, you can change the equation into 
Cancel out the y on the top and bottom and you get 1/10
#5
, simplify and you get
so x=15
is equal to
after you plug in x, and that is equal to 9
