Answer:
Step-by-step explanation:
Use a proportion to solve for the missing side length - a/c = b/d.
4/2 = 6/s cross-multiply
4s = 12 divide by 4
6-2=4 whole number
4/5-1/5=3/5 fraction
put the fraction and whole number toger and you'll get
since the denominator is the same it's easier to subract
4 3/5 <--- answer
Please try to follow me, as I demonstrate a method of solution.
This could get complicated. I'll try to go slowly, and you must
stop me if I do anything that's not clear.
Ready ?
You said that -5c/8 = 20
Multiply each side by 8: -5c = 160
Divide each side by 5 : - c = 32
Multiply each side by -1 : c = -32
