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
Answer:
12-10=2 / (6×5)=30 / 5×2=10 / 12×2=24 / 6+5-2=9
The answer is -3 because you have to add 9 to both sides, then you have to divide by -7 to both sides to get your answer: f = -3
If you are not sure if the answer is right, then plug the answer in the problem to see your answer is correct or not.
Let the number be x
Form the equation : 5x + 1 ≤ 10
5x ≤ 10-1
5x ≤ 9
X ≤ 9/5
so X can be 9/5 or any values smaller than that.
hope this helps :)
