Answer:
2*(5x - 2) + 2*(3x+1) ; Perimeter = 62 centimeters
Step-by-step explanation:
2*(5x - 2) + 2*(3x+1) = 10x - 4 + 6x + 2
= 16x -2
If x = 4 , then Perimeter = 16*4 - 2 = 64 - 2 = 62 cm
Let’s call the amount of pants x and the amount of shirts y.
12y + 21x = 240
y + x = 14 which could be changed to x= 14-y
now you plug it into the first equation
12y + 21 (14 - y) = 240
12y + 294 - 21y = 240
add the similar terms
12y - 21y = 240 - 294
-9y = -54
cancels the minus signs on both sides
9y = 54
y= 6
now you plug y = 6 into the equation x = 14-y
x = 14 - 6
x = 8
answer: Pam bought 8 pants and 6 shirts
