Answer:
Subtract 2x to bring it to the other side
Step-by-step explanation:
2x+5y=20
-2x. -2x
5y=-2x+20
Find the Vertex Form
y = -(x-3)^2-1
2.5x1.30=3.25
4x4.50=18
2x3.75=7.5
3.25+18+7.5=$28.75 total price
2.5+4+2=8.5lb. total weight
28.75/8.5= 3.38 dollars per pound.
Mrs.Kennedy can divide 315 by 10 and then when she gets her answer she can round up to get her answer.
Step-by-step explanation:
length of a rectangle = (3x+4)
breadth of a rectangle =(2x-1)
perimeter of a rectangle =?
we know that,
perimeter of a rectangle=2 (length+breadth)
2 (3x+4)+(2x-1)
(6x+8)+(4x-4)
(6x+4x)+(4+8)
10x+12
x=12-10=2
x=2#
