18×30%=
18×.30=5.4
5.4 is the amount of clearanceyou get from the item
Know you have to subtract $5.40 from $18.00
18-5.4=12.6
The item is know $12.60
To write this in standard form, you need to eliminate the
fraction in the coefficient of variable x. You can do this by multiplying 8 to
the two sides of the equation:
8(y) = 8[(-5/8)x + 3]
8y = -5x + 24
Transpose the variable x to the other side:
5x + 8y = 24
The answer is 10 as the diameter because it says to estimate pi as 3. Since we know the circumference is 30 we can reverse it to find the diameter, since Circumference is pi time diameter.
It’s $13.75=3x-$2.50 -> $11.25=3x -> $3.75=x
