Percent means parts out of 100
70%=70/100=7/10
7/10 of x=28
'of' means multiply
7/10 x=28
multiply both sides by 10/7 to get rid of fraciton
x=40
the number is 40
If your total is $14.30 and you use a 25% discount you total would then be $10.73
So $10.73 would be your answer
Answer: 0.6
Step-by-step explanation: First, you want so seperate the equations in parenthesis to make solving the equation easier.
(-2/3x-9/8x )-(4/5x)-(1)
So (-2/3x-9/8x) equals -11/24x
And -11/24x-4/5x equals -151/120x
So -151/120x-1 ends up being 0.6.
Answer:
side A is 18.75 cm² greater than side B
Step-by-step explanation:
