Answer:
x = 3
Explanation:
To simplify this equation, don't worry about the -3, since there is one on both sides. Therefore, they cancel out.
So, 9 + x = 4x
When you plug 3 in for x, it becomes:
9 + 3 = 4 x 3
12 = 12
This equation is true, therefore, x is your answer!

<h3>Determine the price of nachos and chocolates </h3>
Two simultaneous equations can be derived from the question:
3n + 3c = $45 equation 1
n = 2c equation 2
Where:
- n = price of nachos
- c = price of chocolate
In order to determine the price of chocolates, please substitute for n in equation 1.
3(2c) + 3c = $45
6c + 3c = $45
9c = $45
c = $45/9 = $5
In order to determine the price of nachos, please substitute for c in equation 2:
n = 2($5)
n = $10
<h3>Amount Kyle paid </h3>
2($10) + $5
$20 + $5
= $25

Answer:
Step-by-step explanation:
Let x = base measurement; then height = (x-4).
A = ½•base•height 48 = ½x(x-4
Pi was discovered way back already the way to Babylonians and Egyptians 216 BC but none were all the way accurate they were close
There isn't enough information; however, let's say you were to find the missing side length of a rectangle. The perimeter is 52 and the two given side lengths are both 16. You would set up an equation to find the missing side lengths:
52 = 16 + 16 + ? + ?
52 = 32 + ? + ?
20 = ? + ?
Since this is a rectangle, the two other sides have to be equal. Therefore, you would divide the number by 2.
10 = ?
