Using a system of equations, it is found that the equation that could be used to find the value of b is given by:
3×4−8=b
<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.
Fatima has 3 packs of batteries. Each pack contains 4 batteries, hence:
b = 3 x 4
She gives her brother 8 batteries to put in his toy robot, hence:
b = 3 x 4 - 8
Which means that the first expression is correct.

Answer:
-45
Step-by-step explanation:
hope this helps
1 - 7 + 7 + 3 + 3 = 20
2 - 3 + 3 + 4 + 3 = 13
3 - 7 + 7 + 2 + 2 = 18
4 - 2 + 2 + 9 + 9 = 22
5 - 3 + 1 + 3 + 1 = 8
20 + 13 + 18 + 22 + 8
33 + 18 + 22 + 8
33 + 18 + 30
63 + 18
= 81
Hello.
1. The outcome would be 1/7 beacuse there are 7 days in a week and there is only one day.
2. <span>0.14285714 and 1/7
3. The answer is neither likley or unlikley.
Its not impossble becasue there is a good chance that could happen.
It wouldnt be likley beacase a 1 to 7 ratio is pretty small when there is 6 more oprtions.
And not unlikley or likley becasue there is a good chance it could happen so the answer would be unlikley.
Have a good day.</span>
