<u>Answer:</u>
96
<u>Step-by-step explanation:</u>
Let's assume that the marks needed in the next exam is . Then if the average becomes 90,
Now we can simply solve for :
⇒
⇒ [Multiplying both sides by 4]
⇒ [Subtracting 264 from both sides]
⇒
Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.
Answer:
width = 5 in
length = 5+4=9 in
height = 2(5)= 10 in
Step-by-step explanation:
A gift box has a volume of 450 cubic inches.
Let 'w' be the width of the box
The width of the box is 4 inches less than the length.
The height is twice the width.
height = 2w
Volume of box = length times width times height
w=5
, this gives two complex values
so width = 5
length = 5+4=9
height = 2(5)= 10
