Answer:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
Build time (hours) = 4c + 6a = 120
Test time (hours) = 4c + 4 a = 100
Where c represents the number of child bikes and a represents adult bikes.
So, for 20 child bikes and 6 adult bikes:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Feel free to ask for more if needed or if you did not understand something.
Answer:
All vertical lines have an equation in the form x=... The number indicates the x -intercept. The line x=0 is the equation for the y-axis.
Since x=5 is a vertical line, there is no y-intercept and the slope is undefined.

I've Included a picture to tell you how to get the diameter as well as the circumference.
Given
To solve for w, the objective is to leave the w-term on one side of the equal sign and all other terms on the other side.
First, apply the exponent -1 to both sides of the expression to invert both terms:
Second, multiply both sides by 15y
Third, add 18v to both sides of the equal sign
Finally, divide both sides by 9 and simplify
The expression written for w is
