Answer:

Step-by-step explanation:
common denominators : (x+6)(x+4)
numerators become difference of squares
and
-
= 20
(x+6)(x+4) = 
A: 2/1 -> 2
B: -1/1 -> -1
Gradient or slope is the change in the y value/change in the x value
Y value is up and down and x value is side to side.
Hope this helps! :)
Answer: $574
Step-by-step explanation:
First we need to calculate the price of the snowboard before the addition of the tax. This will be represented by x. Therefore,
6% of x = $32.50
0.06 × x = $32.50
0.06x = $32.50
x = $32.50 / 0.06
x = $541.67
Therefore, the total cost including the sales tax will be:
= $541.67 + $32.50
= $574.17
= $574
Answer:
She spent 5 hours mowing lawns.
Step-by-step explanation:
To solve, we will just use some algebra
8h + 20 = 60 | Subtract 20 from both sides
8h = 40 | Divide both sides by 8
h = 5
We can confirm this by plugging it back into the original formula.
8(5) + 20 = 60
40 + 20 = 60
60 = 60
Answer: The experimental probability of 2/9
Step-by-step explanation:
2/18= 1/9 * 2= 2/9 so on the first try,she sold 2 out of 18 which means the experimental probability is 2/18 = 1/9 so since this is the second try, you will have to multiply 1/9 by 2 to find the next possible outcome.
