Shoes= 10
Man= 5
Tie= 4
So, 10+5*4= 30 <— Answer
How to get variables:
Shoes:
3 shoes are equal to 30, so to find the value of the shoes use 3x=30. X=10
Man:
2 men and a shoe is equal to 20. So, 2x+10=20
2x=10
X=5
Tie:
2 ties and a man are 13. So,
2x+5=13
2x=8
X=4
Convert 2ft to inches
1ft=12 inchestimes 2 both sides2ft=24 inches
24 in used means -24
40-24=16
she has 16in left of ribbon
You must solve for y.
2x - 2y - 3 = -3
Add 3 to both sides.
2x - 2y = 0
Subtract 2x from both sides.
-2y = -2x
Divide both sides by -2.
y = x
