Always
a=b
subtract c from each side
a-c = b-c
Answer:
$69.90
Step-by-step explanation:
I multiplied $65 with 0.075 (Tax percentage). I got 4.875. I rounded that up to 4.9 (Tax). Then, I added the tax with the original price ($65) and I get $69.90
The answer is 0.008. Hopefully you understand why :)
Answer:
10
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + (sqrt(19))^2=c^2
81+19 = c^2
100 = c^2
Take the square root of each side
sqrt(100) = sqrt(c^2)
10 = c
The hypotenuse is 10
If you simplify using the distributive property you should get D
