Answer:
see bottom
Step-by-step explanation:
divide through by 4
x2 - 2x - 3 = 0
x2 - 3x + x - 3 = 0
(x2 - 3x) + (x - 3) = 0
x(x - 3) + 1(x - 3) = 0
(x + 1) (x - 3) = 0
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3
10 the answer is 10 pemdas
The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price. This is because you usually have the new price being given to you so you compare it with the old price to know the percent discount.
Answer:
x = -6
Step-by-step explanation:
(2x/3) + 10 = (x/5) + (36/5)
15*[(2x/3) + 10 = (x/5) + (36/5)] <em>[Multiply both sides by 15 in order to convert the fractions to whole numbers]</em>
(15/3)*2x +15*10 = (15/5)x + (15/5)*36
5*2x + 150 = 3x + 3*36
10x +150 = 3x + 108
7x = -42
x = -6
===
<u>Check:</u>
Does (2x/3) + 10 = (x/5) + (36/5) work for x = -6?
(2(-6)/3) + 10 = (-6/5) + (36/5) ?
-4 + 10 = (30/5) ?
6 = 6 YES
