Answer: 42
Step-by-step explanation:
Ok what you want to do is add all of them up and equal it to 180 because a triangle is 180 degrees .
Your equation should look like this
9x-3+22x+1+42-3x = 180
What you want to do first is combine all the x and numbers on the left side so it should look like this
1) 28x+40= 180
Then you want to subtract 40 on both sides so it will look like this
2)28x=140
You want to get x by it self so you divide 28 on both sides
3) x=140/28
4) x=5
Since you are finding c you have to insert 5 into x
1) 9(5)-3
2)45-3
Then your answer should be 42
Yes it is a direct variation
To find the distance traveled, we multiply the speed by the time. In this case, one person travels 60t miles in one direction, and the other person travels 50t miles in the other direction. So at any time t, the distance between the two people is 60t + 50t = 110t.
Given that the distance between them is 440 miles, we can solve for t with the following equation:
110t = 440
t = 4 hours
