3 0

5n + 3 + 4n = 30                     combine the like terms on the left

9n + 3 = 30                              Subtract 3 from both sides

9n = 30 - 3

9n = 27                                     Divide by 9

n = 27/9

n = 3

The correct answer is D but i don’t understand
iren [92.7K]
The answer depends on the way you solved it.

I am assuming you take the base on which you perceived to be: . 5 and height which is 2.


So you must've ended with 1

But in actuality, you need to use the equation above and plug in 1.5 and 1
Subtract them and you should get 1.25

Do the same to the other side, you should get 6.

.125 x 6  = .875

s344n2d4d5 [400]

Answer:

12 cups

Step-by-step explanation:

The first step is to calculate the volume of the cubiod

= 36 × 6 × 23

= 4968

= 4968/3 ×2

= 1656×2

= 3312

Therefore the greatest number of cups can be calculated as follows

= 3312/275

= 12

Hence the greatest number of cups is 12 cups
