<h2 /><h2>Answer: 18</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />
First we need to substitute the value of the variable into the expression.
=
.
Now we need to solve
.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First, calculate 3 to the power of 2 and get 9.

Multiply 2 and 4 to get 8.
Subtract 5 from 8 to get 3.
Multiply 3 and 3 to get 9.
.
<h2>And the answer is, you guessed it, 18!</h2>
Z=72, i was working on it and that’s what i got
Answer:
Step-by-step explanation:
the answer would be nine
Using a system of equations, it is found that £52 was originally shared.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: Angela's share.
- Variable y: Michelle's share.
- Variable z: Daniel's share.
Angela and Michelle shared some money in the ratio 4: 9, hence, considering t as the total:
.
Angela gave Daniel half her share.Michelle gave Daniel a third of her share. Daniel was given a total of £20, hence:



30t = 20 x 78
t = 20 x 78/30
t = £52.
