8x-5y because 7x plus x is 8x and -6y+y is 5y
Answer:
y=-x
Step-by-step explanation:
the first two are correct, but the answer for c should be 125
A pair of jeans = $40.00
There is a 6.5% sales tax.
First change the % into a decimal by moving the decimal point two spaces to the left.
0.065
Multiply that by 40.00 to find out how much the tax is.
40 × 0.065 = 2.6
Now add the tax to the initial price.
40.00 + 2.6 = 42.60
The total cost is $42.60.
