Answer:

8x +36 = 15

Step-by-step explanation:

The fractions can be made to disappear by multiplying the equation by their least common denominator. That number is 18.

18(4/9x +2) = 18(5/6)

8x +36 = 15

The solution is x = -21/8.

I’m 100000% it’s true
4/9x +2=5/6
8x +36=15
8x=15-36
8x=-21
x= -21/8
x= -2 5/8

The rectangular prism below has a total surface area of 198 in2. Use the net below to find the missing dimension, x.

Answers

The missing dimension, x, is 7.5.

if you take 45 and divide it by 6 you can get the next dimension needed to get the full number, 45. You can also find it by dividing 35 and 4. I hope this helps.

The missing dimension of the rectangular prism is x = 7.5 inches

What is the surface area of the prism?

The surface area of the prism is calculated as

The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism

Surface Area of the prism = 2B + ph

The area of the triangular prism is A = ph + ( 1/2 ) bh

Given data ,

Let the total surface area of prism be S = 198 inches²

Let the length of the missing side of prism be x

Now , the area of the side is A = 30 inches²

The length of one side y = 4 inches

So , the equation is A = xy

On simplifying , we get

30 = x ( 4 )

Divide by 4 on both sides , we get

x = 30/4

x = 7.5 inches

Hence , the missing side of the prism is x = 7.5 inches
