Answer:
Step-by-step explanation:
the price for the whole sale is 260/20=13
if the store is selling one sweater for 17.55
the percentage increase
17.55-13=4.55
4.55/13=0.35
0.35*100=35%
the increase was 35%
Answer:
NO
Step-by-step explanation:
To find if they are equivalent, we need to simplify them first.
Using the distributive property we get:
6(4x-5) = 24x - 30
In this case we need to combine like terms.
3 + 22x - 33 - 2x = 20x - 30
So now we can compare.
24x - 30 ≠ 20x - 30
So we can conclude that the two expressions are not equal because 24x - 30 and 20x - 30 are obviously not equal.
Answer:
-4
Step-by-step explanation:
I used a calculator lol
You can find the x intercept by setting y to 0 and factor the equation.
0=2x^3+3x-2
0=(2x-1)(x+2)
We can make this equation =0 if x is -2 and 1/2.
So the x intercepts are (-2,0) and (0.5,0)
