If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16        3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16    -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24.    24-16=8.    3x12=36     36-8=28    And, You're done!

charle [14.2K]

Answer:

4 feets = 48 inches

2 miles = 10,560 feets

1 2/3 yards = 5 feets

3 1/2 yards = 126 inches

Step-by-step explanation:

Recall :

1 Feet = 12 inches

1 MILE = 5280 feets

1 yard = 36 inches

1 yard = 3 feets

If 1 feet = 12 inches

4 feets will be ; (12 * 4) inches = 48 inches

If 1 mile = 5280 feets

2 miles will be ; (5280 * 2) = 10,560 feets

If 1 yard = 3 feets

1 2/3 yards will be ; (5 /3) * 3 = 5 feets

If 1 yard = 36 inches

3 1/2 yards will be ; (7 /2 ) * 36 = 126 inches
