36/4=9 48/3=16 so 9*16=144/2=72 so it is 72 square inches
Answer:
11, 15, 26, 41, could be an answer
It is 70
i cant explain it right now i have work to do so sorry:)
For 1
Twice a number means
A number used two times
Is that number was x
What do we do to x
So here you're using system of equations. You can solve systems by graphing, elimination, or substitution. Ill use substitution. First lets solve for x. take the second equation and add y to both sides to get x by itself:
x - y = 75
x = y + 75 now plug y+75 in for x in the first equation
x + y = 743
(y +75) +y = 743 solve for y
2y +75 = 743 subtract 75
2y = 668 divide both sides by 2
y = 334
now plug this into any of the 2 equations to solve for x i chose the second one
x - y = 75
x - 334 = 75 add 334 to both sides
x = 409
This means x, sold before the tournament is 409 and y, sold at the door is 334. That means the assistant is wrong and accidentally flipped the two answers
