Where's the graph?? I can't answer if there's no graph. lol xD
You know that the angle measurements in a triangle add up to 180 degrees.
using the equation 3x+4x+2x= 180, you can find x
Simplify:
9x=180
x=20
Your answer is B) x = 20
Hope this helps!
Rate of Daniel - x:
4.95 (40 ÷ 9 + x) = 40
22 + 4.95x = 40
4.95x = 18
x = 40 ÷ 11
Time for Paul to gather 40 bushels:
= 40/(40 ÷ 11)
= 40(11 ÷ 40)
= 11
Hope I helped!
