Answer:
-539.25
Step-by-step explanation:
(w^2x−3)÷10⋅z
w=−9, x = 2.7, and z=−25
((-9)^2*2.7−3)÷10⋅(-25)
Parentheses first
The exponent in the parentheses
(81*2.7−3)÷10⋅(-25)
Then multiply
(218.7−3)÷10⋅(-25)
Then subtract
(215.7)÷10⋅(-25)
Now multiply and divide from left to right
21.57*(-25)
-539.25
Add 18 to both sides to get:
px = 22
Then divide both sides by p to get:
x = 22/p
The answer is C.
Subtract the part from the total:
102.50 - 15 = 87.50
Now divide the remainder by rate:
87.50 / 25 = 3.5 hours
the answer is 4 because 16 and 20 can both be divided by 4.
Well a dime is 10 cents each so 2 dimes would be 20 cents. a dollar is 100 cents. 20/100 which is also 1/5 of a dollar.
