Percent means parts out of 100
x%=x/100
1 yard=3 feet
2 feet is what percent of 3 feet?
2=x% times 3
2=x/100 times 3
2=3x/100
multiply both sides by 100
200=3x
divide both sides by 3
66.6666666=x
answer is 66.66666%
Answer:
-5 < x <=-2
Step-by-step explanation:
9<=1-4x<21
Subtract 1 from each side
9 -1<=1-1-4x<21-1
8 <= -4x < 20
Divide each side by -4. That means to flip all inequalities
8/-4 >= -4x/-4 >20/-4
-2 >=x > -5
-5 < x <=-2
Answer:
The number is -5.
Step-by-step explanation:
x+x=x-5
2x=x-5
x-2x=5
-x=5
x=-5
