Step-by-step explanation:
75-48.75= 26.25
26.25/48.75x100= 53.8461538462 Round 53.85%
Check Answer:
48.75 x 53.85%=26.251875 Round 26.25
48.75 + 26.25=75
Hence, the correct answer is 53.85%.
Answer:
X = -2 and 4
Step-by-step explanation:
Move all of the terms to one side and set the equation to 0:
2x^2-14x+40-3x^2+16x-32 = 0
Then combine all like terms which would look like the following:
-x^2 + 2x + 8=0
Change the signs on both sides of the equation:
x^2 - 2x - 8 =0
Write -2x as a difference:
x^2 + 2x - 4x -8 = 0
Factor the expression:
x(x+2) x 4(x+2)=0
Factor out x+2 from the equation:
(x+2) (x-4)=0
Split into classes and then find the answer from there:
x+2=0
x-4=0
