To solve this, you cross multiply, then divide. In this case, we multiply 4 and 2, then divide by 3.
4 x 2 = 8
8 / 3 = 2.66
So, x is 2.66
Answer:
7
you can alway convert the fraction to a decimal so it'll be
1/5(1 divided by 5)=0.2
0.2*35=7
Answer:
18 Pounds
Step-by-step explanation:
Variable: s=how much you sister weighs
One equation would be:
94 - s = 112
You then have to isolate the variable by subtracting 94 from each side to get:
s=18
I don't if I explained it that well.
The formula for perimeter is 2l+2w. Since we know l=(w-4)-9, we can substitute this into the formula.
l=w-13
2(w-13)+2w=143
2w-26+2w=143
4w=169
w=42.25 units
Hope this helps!
