Answer:
First one is 13. The second is 12
Step-by-step explanation:
First Scenario:
The entire line is a total of 23. Above the line it creates three segments which break up the 23 in different parts. Therefore, in other words, (x - 6) + (9) + (2x - 19) = 23. So I added all my liked terms together and simplified to get me the value of 13.
Second Scenario:
Just like in the first scenario, the second scenario provides the information that the entire line is 32. However in this case the line is split up in two different sections as indicated above the line. In which provides you with the information with the two line segments being ? (or x in this case) and 20. Therefore you would set it up the same way as in the first scenario because these two parts added together gives us the entire length of the line. So I said x + 20 = 32, which in return gave me the value to be 12.
Answer:
-9x+3
Step-by-step explanation:
See the steps below:)
Use order of operations (PENDAS)to divide 1/4 by 5/6 (remember to use the reciprocal of the second number). Than find GCF with that number you have now and 4/9 to get your answer.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
<u>Time:</u>
- 120/x = 120/(x + 20) + 1
- 120(x + 20) = 120x + x(x +20)
- 120x + 2400 = 120x + x² + 20x
- x² + 20x = 2400
- x² + 2*10x + 10² = 2500
- (x + 10)² = 50²
- x + 10 = 50
- x = 40
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
