Answer:
Perimeter: 2(3x+6)+ 2(2x-4)
X=9
Step-by-step explanation:
In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:
Perimeter: 2(heights)+ 2(bases)
Perimeter: 2(3x+6)+ 2(2x-4)
IN order to solve for X we just have to insert the value of perimeter, which is 94:
Perimeter: 2(3x+6)+ 2(2x-4)
94=2(3x+6)+ 2(2x-4)
94= 6x+12+4x-8
94=10x+4
94-4=10x
x=90/10
x=9
So the value of x would be 9.
Answer:
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
Step-by-step explanation:
Assume;
Cost of chip cookies = c
Cost of ginger cookies = g
So,
Maya's sales = 8c + 12g = 374
.....Eq1
Carlo's sales = 2c + 4g = 113
.......Eq2
4 x eq2
So
8c + 16g = 452......Eq3
Eq 3 - Eq 1
4g = 78
g = 19.5
and
c = 17.5
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
