Answer:
A. 15
Step-by-step explanation:
V of a right prism which this is. Is LxWxH
So 1.5x 4x2.5=15
By just changing the x and numbers you can solve it:
-4x=-8 => x=2
Work problems are solved by first figuring out how much of the job they can do in each hour. Shawn can do 1/4 of the job in an hour and Ellie can do 1/6 of the job in an hour. 1/6+1/4=2/12+3/12=5/12. This means that they can do 5/12 of the job an hour. This means that together they can do the job in 2 2/5 hours. The foreman is obviously wrong because first of all Shawn can do it alone in 4 hours, so with Ellie he will do it faster, and second of all 2 2/5<5. Hope this helped!
Make an equation
X+X+200=1500
Isolate the variable
2x=1300
X=650
Know that we know what X is, we know that X + 200 will equal the cost of the second appliance
650+850=1500
