Answer:
Step-by-step explanation:
First I just made -2/5 into a decimal because I like to work with decimals better (which equals -.4)
Then I times everything separately in the parenthesis and got -8x+6
Next you move the 6 over to the left side of the equals sign which would make the equation be -6 = -8x
Lastly you divide the -8 from -6 and you get X = 3/4
Answer:
36
Step-by-step explanation:
3*2=6
6^2=6*6
=36
Using a system of equations, it is found that since 20 child bikes and 6 adult bikes would require more testing than the allocated time, it is not possible to build this amount.
<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:
- Variable c: number of child bikes.
- Variable a: number of adult bikes.
Each child bike requires 4 hours to build, as do each adult bike. The company has 100 hours of testing, hence:
4c + 4a = 100.
c + a = 25.
With 20 child bikes and 6 adult bikes in a week, we have that c = 20, a = 26, hence:
c + a = 26
20 child bikes and 6 adult bikes would require more testing than the allocated time, it is not possible to build this amount.

the associative property of addition. Try and memorize the different properties. youll need to know them later on. I hope this helped!
That sequence is not geometric or arithmetic
it is not changing or doing anything it is just remaining the same.
it would be geometric if it was:
1+1-1+1-1+1........
