Answer:
180x ft cubed
Step-by-step explanation:
1) The formula for the volume of a rectangular prism is length x width x height
... shortened it is "lwh"
2) Plug your numbers (and "x") into the equation doesn't tell you which is which, but since we are multiplying it doesn't matter.
It should now look like this "(15)(12)x"
3) Simplify.
180x ft cubed
X = number of DVDs
1 DVD costs $1.95 to rent
x DVDs cost 1.95x dollars to rent
tack on the membership fee of 4.95 and the total cost is 1.95x+4.95
set this equal to 42 and solve for x
<span>1.95x+4.95 = 42
</span>1.95x+4.95-4.95 = 42<span>-4.95
</span>1.95x = 37.05
<span>1.95x/1.95 = 37.05/1.95
</span>x = 19
So Shanti can rent 19 DVDs
All you have to do is divide the number by the denominator which is 8. So 510 divided by 8.
Which will give you 63.75.
Then you times it by the numerator which is 3 so 63.75 x 3
And you are left with £191.25 which is 3/8 of 510
