Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
The answer is b= - 5/2
- 6 (b + 3)= - 8 + 5
- 6b - 18= - 3
- 6b= - 3 + 18
- 6b= 15
b= - 15/6
b= - 5/2
Answer:
m>3 or m<-5
Step-by-step explanation:
First simplify -3m-1 < -10:
-3m < -9
m > 3 (switch direction of sign when dividing by negative number)
Then simplify -4+2m<-14:
2m<-10
m<-5
m>3 or m<-5
Answer:
308
Step-by-step explanation:
let the number be x
then,
94.248=30.6% of x
94.248=30.6/100 *x
94.248= 0.306x
94.248/0.306=x
308=x
so the number is 308.
