Answer:
Janelle's height is 82 units.
Step-by-step explanation:
Let j represent Janelle's height.
It is mentioned that, 58 is the difference between Janelle's height and 24.
Mathematically, we can write it as :
j-24 = 58
We can solve it as follows :
Adding 24 both sides,
j-24+24 = 58+24
j = 82
Hence, Janelle's height is 82 units.
A prism's volume is the area of the face that does not have more than 1 equal counterpart mulitplied by the height of the entire prism, in which the height of the prism is not any of the sidelengths of the face whose area is being multiplied.
Answer:
x = 2/7
Step-by-step explanation:
Step 1: Write equation
20x + x - 2 = 4
Step 2: Solve for <em>x</em>
- <u>Combine like terms:</u> 21x - 2 = 4
- <u>Add 2 to both sides:</u> 21x = 6
- <u>Divide both sides by 21:</u> x = 6/21
- <u>Simplify:</u> x = 2/7
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
20(2/7) + 2/7 - 2 = 4
40/7 + 2/7 - 2 = 4
42/7 - 2 = 4
6 - 2 = 4
4 = 4
