21/2 = 10 1/2 10 1/2 x 3 = 31 1/2
31 1/2 miles is how much she runs in a week
so then you multiply this by six, 31 1/2 x 6 which is 189 miles
So Jill runs 189 miles

Answer: X=1/72
Step-by-step explanation:
3/8x-17=10
We move all terms to the left:
3/8x-17-(10)=0
Domain of the equation: 8x!=0
x!=0/8
x!=0
x∈R
We add all the numbers together, and all the variables
3/8x-27=0
We multiply all the terms by the denominator
-27*8x+3=0
Wy multiply elements
-216x+3=0
We move all terms containing x to the left, all other terms to the right
-216x=-3
x=-3/-216
x=1/72
Answer:
8/15
Step-by-step explanation:
The reason is because to multiply, you take the reciprocal of the fraction...
So
4/5/3/-2, right? So that's basically -4/5 ÷ 3/-2 so 4/5 * -2/3. The reciprocal of a fraction is literally just flipping it. Now, you know how to multiply, right?
-4/5 * -2/3 = (you can't simplify) 8 (negative times negative = positive) / 5*3
so 8/5*3 = 8/15. 8/15 is 0.53333, or you can just keep it as a fraction.
