In this question, you're solving for x.

Solve for x:

2(4 - 8x) + 5(2x - 3) = 20 - 5x

Use the distributive property:

8 - 16x + 5(2x - 3) = 20 - 5x

8 - 16x + 10x - 15 = 20 - 5x

Combine like terms:

8 - 16x + 10x - 15 = 20 - 5x

8 - 6x - 15= 20 - 5x

-6x - 7 = 20 - 5x

Add 5x to both sides

-x - 7 = 20

Add 7 to both sides

-x = 27

Divide both sides by -1

x = -27

Answer:

x = -27

What is the equation of the line that passes through the point (-4,4) and has a<br> slope of -3
Arte-miy333 [17]

Answer: y-4=-3(x+4) or y=-3x-8

Step-by-step explanation:

To find the equation of the line with a given point and slope, we can fill them into the point-slope formula. The point-slope formula is y-y₁=m(x-x₁).

y-4=-3(x-(-4))            [multiply]

y-4=-3(x+4)

Another equation could be slope-intercept form. It is y=mx+b.

y-4=-3(x+4)              [distribute]

y-4=-3x-12                [add both sides by 4]

y=-3x-8

Now, we know that the equation is y=-3x-8 or y-4=-3(x+4).

A five-sided solid has the numbers 1, 2, 3, 4, and 5. What is the probability of rolling two five-sided number solids and gettin
Klio2033 [76]
We assume the probability on each side is equally probable with probability 1/5.
sum=4 has outcomes:{1,4; 2,3; 3,2; 4,1}  4 possible outcomes
sum=8 has outcomes:{3,5; 4,4; 5,3} 3 possible outcomes.
Total possible outcomes = 5*5=25
there probability of rolling a sum of 4 or 8, by the law of addition, equals
4/25+3/25=7/25

Note: a regular (i.e. fully symmetric) five-sided solid does not exist, so there has to be asymmetry among the probabilities of the five possible outcomes.  In addition, it does not have a "top" face, so that makes rolling a five-sided solid a little more difficult to visualize.
