an American football field is a rectangle with a perimeter of 1040 feet the Lenght is 200 feet more than the width find the demensionof the field

1040 = 2L + 2W

L = W+200
Two equations; two unknowns. Substitute 2+200 for L into the first equation and solve for W.

answers is Demensions of the field 1240

That should be "substitute W+200 for L into the first equation and solve for W."

answer 12038of the demension

if a number is subtracted 94,result 19more than the product of 5 and the a number

-94x=19(5)=x=1

answer x=1
