Answer:
x = 17
Step-by-step explanation:
First, let's turn this into an equation:
twenty more ( +20 ) than four times a number ( 4x ) is equal ( = ) to the difference ( - ) between 139 and 3 times the number ( 3x ).
4x + 20 = 139 - 3x
Now let's solve:
Subtract 20 from each side:
4x = 119 - 3x
Add 3x to each side:
7x = 119
Divide each side by 7:
x = 17
Yes the correct answer is D. Hope this helps :)

Here, we want to make a description
Mathematically, a prism is a solid shape with parallel bases, separated by a particular height
To find the volume of the prism, all we have to do is to find the area of one of the bases
After this, we then multiply the value obtained by the height of the prism. This gives the volume of the prism
