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
I'm not sure if it is A or B

(-72×-11) / (-7x-48) =
792 / 336 = 2.36
or the fraction in simplest terms is 33 / 14
So when you add mixed numbers, you must convert it into fractions. The four would become part of the fraction and be 43/10 and the six becomes part of the fraction which is 69/10. You can find this by multiplying 4 by the denominator and then adding it to the numerator (4 Times 10 = 40 + 3 = 43/10) and same for the other one. The answer is 112/10, simplify to 11 1/5.
