Answer:
C
Step-by-step explanation:
143.75+ tax(7.1875)= 150.9375 <-- Tennis Ball Containers
30+ tax(1.5)= 31.5 <-- Packs of Grip Tape
150.9375+31.5= 182.4375
This can be rounded up to 182.44 (which is your final answer)
Answer:x = -1.5
Step-by-step explanation:
Simplifying
7x + -9x = 3
Combine like terms: 7x + -9x = -2x
-2x = 3
Solving
-2x = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-2'.
x = -1.5
Simplifying
x = -1.5
So you always want to pull out the gcf first but since there isn't one, we can move on.
so we can make an acb chart which is multiplying the a value and the c value and find factors that of that product that will equal the b value.
a value is 2
c value is -15
b value is 7
-30 factors to equal 7 = 10, -3
10 - 3 = 7
so the factors 10 and -3 work.
so now you make 2 separate parenthesis with one of the factors and one x. and it should be set equal to 0.
(x+10)(x-3) = 0
now solve for x in each separate parenthesis.
x = -10
x = 3
those r the roots
