Answer:
The answer is B
Step-by-step explanation:
-53=8x+5
First you would subtract the 5 on both sides then you would end up with
-58=8x
then you would divide both sides by 8 and get 7.25 or 7 1/4
182 m^ (Third answer) because it is not the volume
2 rectangles measuring 17x2 2(17x2)= 2x34 = 68 m^
2rectangles measuring 17x3 2(17x3)=2x51+102 m^
2rectangles measuring 3x2 2(3x2)=2x6=12 m^
TOTAL---------------------------------------------------------182 m^
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.
