8x - 12 = 28
add 12 to both sides
8x = 40
divide
5
Answer:
Start with what we know:
4(2x-3) = 28
Now we do rainbow property aka distributive property:
4*2x=8x
4*-3=-12
now we have:
8x - 12 = 28
we have to get 8x alone:
we will add 12 to both sides:
8x= 40
now we have to get x alone:
8x/8=x
40/8=5
now we put that into a equation:
x=5

You and your mom enter a drawing with 3 different prizes. The prizes are
awarded at random.
If a total of 10 people entered the drawing, in how many ways can you win
first prize and your mom win second prize?
a. 8
b. 2
c. 10
d. 1
Answer:
The correct answer is 8.
Step-by-step explanation:
There are 2 ways that you can win first prize and your mom can win the second prize.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 10 people who entered the drawing.
Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.
We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.
The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.
Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.
The total number of ways that you can win first prize and your mom can win the second prize is:
1 × 1/3 × 1/2 × 9 = 3/2
However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.
Therefore, we round up to the nearest integer and get:
3/2 ≈ 2
Therefore,
There are 2 ways that you can win first prize and your mom can win the second prize.

1. Which is the slope of the line that passes through the points (1,1) and (2,7) ?
1a. Pick a point the line passes through above and with the slope you calculated, find the y- intercept
1b. Now that you know the y- intercept, what is the equation of the line ?
Hello!
1)First, they ask us to find the slope. [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex] is the slope formula.
The slope is 6
2)Let's just use the point they gave us (1,1)
We need to substitute the point in the equation and solve.
The y-intercept is -5
3) y=mx+b (m=slope b=y-intercept)
y=6x-5
I really hope this helps :-)
Write an equation in slope-intercept form of the line shown.
Answer:
Step-by-step explanation:
y2-y1/x2-x1
1+3
3-1
your slope is 4/2 or 2. keep going down to find what y is when x is 0, which happens to be -5
so now you have a slope and a y intercept you can solve like y=mx+b where m is your slope and B is your y intercept
y=2x-5 is your answer

Perform the indicated multiplication: 2 - 3x - 12 = 9 - 3x
Gather all the x terms on one side and all the constants on the other:
-3x + 3x = 9 + 12 - 2, or 0 = 19
since this is never true, 2 - 3x - 12 = 9 - 3x has no solution.
