Ok so the amounts are x and 100-x
0.24x+0.5(100-x)=0.36(100)
solve
0.24x+50-0.5x=36
-0.26x+50=36
mminus 36 both sides
-0.26x=-14
divide both sides by -0.26
x=53.8462
find other one
100-x=100-53.8462=46.1538
53.8462 gallons of the 24%
46.1538 gallons of the 50%
I think it is one plus one
Answer:
7
Step-by-step explanation:
area of parallelogram = l* h
91 = 13 * h
91/13 = h = 7 cm
We can change the law of sines a little bit to match our problem.

We know what angle Y is and what side y is, so let's use that along with angle Z and side z:

Plug in what we know:

Multiply 'z' to both sides:

Divide sin(51)/2.6 to both sides:
