Answer:
Step-by-step explanation:
3x + 50 = 6x - 10
Bringing like terms on one side
50 + 10 = 6x - 3x
60 = 3x
60/3 = x
20 = x
In the diagram, parallel lines l and m are cut by transversal t. (4x-15) (2x+21) What is the value of x
Answer:

Kevin drove for 4 hours and then stopped to eat dinner. The total distance he had driven at different time intervals is shown on the graph below.⬇️
• Using the information in the graph, determine Kevin’s average speed during these 4 hours.
• Kevin will drive for an additional 2 hours after dinner. He expects to drive 130 miles during these 2 hours, under the same driving conditions as the trip represented in the graph. Is this a reasonable expectation? Explain your answer and show your work.
Answer:
If you want a simple average, you can add all the speeds you see and divide them by the number of how many they are.
So firstly you have to calculate the speed of the first point, which is:
20 miles/0.5 hour
That means: 40 miles/hour
That would be your first "speed"
Then you calculate all of them :speed1+speed2+speed3 = something.
As an example: 20miles/hr + 40miles/hr+0miles/hr = 60miles/hr
Then, you divide it by how many "speeds" they are: 60miles/hr divided by 3 if I continue my previous example.
It is my first answer, and I hope I could help you a bit!

Answer:
[tex]y=-\frac{2}{3} +4[/tex]
Step-by-step explanation:
2x + 3y = 12
subtract 2x from both sides
3y = -2x + 12
divide both sides by 3
y = -2/3x + 4
Which problem demonstrates the associative property of multiplication?
(5.2 • 3.1) • 1.9 = 5.2 • (3.1 • 1.9)
5.2 (3.1 + 1.9) = (5.2 • 3.1) + (5.2 • 1.9)
(5.2 + 3.1) + 1.9 = 5.2 + (3.1 + 1.9)
5.2 + 1.9 + 3.1 = 10.2

Geometry geometry geometry
Answer:
x = 1
Step-by-step explanation:
The proportion in this question is (3z) : (3z)+(z+22) = (2x+1) : (8x-2), since there are two triangles that are similar.
The question said that 3z = z+22
--> 2z = 22
--> z = 11
So our new proportion will be:
--> (3z) : (3z)+(z+22) = (2x+1) : (8x-2)
--> (33):(66) = (2x+1):(8x-2)
--> (66)(2x+1) = (33)(8x-2)
--> 132x + 66 = 264x - 66
--> 132x - 132 = 0
--> 132x = 132
--> x = 1

Choose the answer based on the most efficient method as presented in the lesson.
If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then what should the next step be?
subtract 5x
add 8
subtract 3
Answer:
You would not subtract 3...
Step-by-step explanation:
It should be
2x- 8= 5x+3
subtract 5x from both sides,
then add 8 onto both sides, then you would get 0 on one side, and 11 on the other so you would have
-3=11 which equals
3.6
Answer
add 8

Find the value of x!
Answer:
x = [tex]\frac{16}{3}[/tex]
Step-by-step explanation:
Since the triangles are similar then the corresponding sides are congruent.
EF and BC are corresponding sides , then
8x - 3 = 5x + 13 ( subtract 5x from both sides )
3x - 3 = 13 ( add 3 to both sides )
3x = 16 ( divide both sides by 3 )
x = [tex]\frac{16}{3}[/tex]
