Answer:
4,687.5
Step-by-step explanation:
The volume of a rectangular microwave can be found by using the following formula... (This formula is a formula for finding the volume of a rectangular prism).
Volume = Length x Width x Hight
(In our case deepness is the length, so we get that...)
Volume = 18.75 x 20 x 12.5
Volume = 4,687.5
(4x+5y=7
y=3x+9
4x+5(3x+9)=7
4x+15x+45=7
19x=7-45
19x= -38
19×/19=-38/19
x= -2
whlie y=3x+9
y=3(-2)+9
y= -6+9
y=3 end solution
x= -2,y= 3

6.5% x 300 = 0.065 x 300 = 19.5
300+ 19.5 = 319.5
