Plug in 83 for y and 3 for x
83 = 3^2 - 6 (3) + 92
83 = 9 - 18 + 92
83 = -9 + 92
83 = 83 so it works
Answer:
5 bows
Step-by-step explanation:
Total feets of ribbon = 3 1/2
Fraction required to make a bow = 2/3
Number of bows that can be made = (total ribbon / Fraction required to make a bow)
3 1/2 ÷ 2/3
7/2 ÷ 2/3
7/2 * 3/2
= 21 / 4
= 5.25
a straight line is 180 degrees so we can find C by subtracting 140 from 180
180-140 = 40 degrees
all 3 inside angles need to equal 180 so now we have
180 = 40 + (2x) + (x+2)
180 = 40 +3x +2
180=42+3x
138=3x
x= 138/3 = 46
check : 2x= 2*46 = 92
x+2 = 46+2 = 48
92 +48 +40 = 180
so x = 46 degrees
so angle B = 2x46 = 92 degrees
