Answer:
x = 5
Step-by-step explanation:
4x + 8 - 9x = -17
combine like terms:
-5x = -25
divide both sides of the equation by -5:
x = 5
Answer:
x=5
Step-by-step explanation:
4x-9x+8=-17
-5x+8=-17
subtract 8 from both sides and you get:
-5x=25
divide 5 from both sides, and you get x=5! :)
True or false? The experimental probability or relative frequency is based on actual results from an experiment and may differ from the theoretical probability of an event occurring. The Experimental Probability will be almost the same as the Theoretical Probability as the number of trials of an experiment is very small
Answer:
a. False
b. False
Step-by-step explanation:
a. The experimental probability or relative frequency is based on actual results from an experiment and may differ from the theoretical probability of an event occurring.
This statement is false because, both the experimental and theoretical probability must agree for the probability of the event occurring to the true.
If both do not agree, that means we have two different probabilities for a s ingle event, which cannot be true. So, the statement is false.
b. The Experimental Probability will be almost the same as the Theoretical Probability as the number of trials of an experiment is very small
This statement is also false because, the experimental and theoretical probabilities only agree when the number of trials of an experiment become large. For small number of trials, both the experimental and theoretical probabilities might not agree.

total children =63×100/35=180
2. While driving to Denver, the car travelled 1 mile per minute. How far would the car travel in 1 hour?
answer
1 minute =1 mile travelled
1 hour =60minute=60mile travelled
3. The team’s ratio of games won to games lost is 4 to 3. If the team played 42 games, how many did they win?
answer
let ratio be 4x and 3x
4x+3x=42
x=42/7=6
won games =4x=4×6=24
4. Cassie found that the ratio of bees to butterflies in the garden was 10 to 7. If there were 28 butterflies in the garden, how many bees were there?
answer
let ratio be 10x and 7x
no of butterflies=7x=28
x=28/7=4
no of bees =10x=10×4=40

Which letter matches the angle?
Answer:
F, Vertical angles.
Step-by-step explanation:
If you need extra visuals, this might help:
"The angles opposite each other when two lines cross. They are always equal.
In this example a° and b° are vertical angles.
"Vertical" refers to the vertex (where they cross), NOT up/down. They are also called vertically opposite angles."

Answer: The answer is D (Mr. Johnson will earn $140 for 12 hours of work
Step-by-step explanation:
So with process of elimination we can safely say that for every hour Mr. Johnson will earn 12$.
So it is true that *A* e(amount earned)= 12h($12 made per hour)
And if *B* Mr. Johnson makes $12 per hour then in 4.5 hours he will make $54
We also know for a fact *C* Mr.Johnson earns $12 per hour
but in 12 hours Mr. Johnson will make $144 not $140 so *D* is incorrect

Answer:
x = 9/2 or 4.5
Step-by-step explanation:
In order to solve this problem, you first need to identify whether or not the two triangles formed in the image are similar; you can tell that they are similar by the AAA property because they share a vertex, and the other two angles are congruent because of the Corresponding Angles Theorem. Now that you know the triangles are similar, you need to identify the corresponding sides:
x + 6 corresponds to x
21 corresponds to 9 (21 because 30 - 9 = 21)
You can find the scale factor by dividing 21 by 9:
21 ÷ 9 = 7/3
Now that you know the scale factor, you can write and solve an equation:
7/3x = x + 6 (given)
4/3x = 6 (subtract x from both sides)
x = 9/2 (multiply both sides by 3/4)

Answer:
17
Step-by-step explanation:
Well you have to get x by itself so....
subtract 8 from both sides
25 -8 = 17 there is your answer
Hey there!
x + 8 = 25
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 25 - 8
SIMPLIFY IT!
x = 25 - 8
x = 17
Therefore, the answer should be: x = 17
