7x2y-3z
Substitute all the numbers!

So: 7x will be 7(3), 2y will be 2(5) and 3z will be 3(-4)

7(3) • 2(5)- 3(-4)
REMEMBER PEMDAS
First multiply and then subtract, this is the right order:

21•10 = 210
3(4) = 12
So: 210-12= 198

katrin [286]

Let the number of green apples bought be x


Green apples = x

Red apples = 2x

Yellow apples = 1/3 (2x) = 2/3 x


Total = 22 apples

x + 2x + 2/3 x = 22

11/3 x = 22

11x = 66

x = 6


Green apples = x = 6

Red apples = 2x = 2(6) = 12

Yellow apples = 2/3 (2x) = 2/3 (6) = 4


Answer: Green = 6, Red = 12, Yellow = 4

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perime

Pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)
