Answer:
-2.1y + 12.9
Step-by-step explanation:
Answer:
12.9-2.1y
Step-by-step explanation:
Use the distributive property to multiply −0.5 by 12y−9.
8.4+3.9y−6y+4.5
Combine 3.9y and −6y to get −2.1y.
8.4−2.1y+4.5
Add 8.4 and 4.5 to get 12.9.
12.9−2.1y

-(-16m-1)
Answer:
16m+1
Step-by-step explanation:
Knowing about our proprieties about parentheses and negatives, let's solve this out.
A negative multiplied by a negative give you a positive
therefore....
-(-16m-1)= 16m+1
The -1 also receives the negative because the problem was in a parentheses :)

30
X =
Answer: x=32
Step-by-step explanation:
Because a triangle is 180°, the missing angle in the triangle would be 60°.
Because of the 30°-60°-90° angles theorem, The side opposite 90° is double the side opposite 30°, which means that x=32.

what is the answer to 3(x-4)=12 in simplest form ?
Answer:
x = 8
Step-by-step explanation:
You distribute the 3 to x and -4.
[tex]3x-12=12[/tex]
You add 12 to both sides.
[tex]3x=24[/tex]
Then you divide by three on both sides.
[tex]\frac{3x}{3}=\frac{24}{3}\\[/tex]
[tex]x=8[/tex]

Answer:
the green line
Step-by-step explanation:
its closest to the point
Hi there! The answer would be the green line and the dark blue line which is f(x)=2x+3 and h(x)=-2x+2.
Step By Step:
So you need to figure out the line for (2,-2).
This means that you would have to find a line that is between them which is the correct answer.
Well it can’t be orange since that it didn’t touch it and so can it not be red. So we have two answers left to choose from.
The last two pairs we have left would be the answer since they’re nothing touching the point for (2,-2).
This means that it would be D, dark blue and orange, or we can say f(x)=2x+3 and h(x)=-2x+2.

If the radius of a circle is 5 inches, what is the diameter of that circle? Show
your work and label your answer.
Answer:
If the radius of a circle is 5 inches, the diameter is 10.
Step-by-step explanation:
This is because to find the diameter of a circle sing the radius is to multiply it by two. 5x2=10
So the diameter is 10. If you want to find the radius just reciprocate the process, divide the diameter by 2 and yo will get the radius.
I really hope this helped you out. Make sure to give my answer brainliest. Have a radiant day or night ! :D

Convert 3 weeks to hours. Use a lable.
Answer: 504 hours.
Step-by-step explanation: I am assuming it says, use a table not a lable.
Well, I can't make a table, so I will tell you where to put everything in a table.
We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.
24 x 7 = 168 and 1 x 7 = 7
So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by the 3 weeks. So we multiply 168 by 3 which is 504.
So 504 hours are in 3 weeks.

Miley can walk 5 1/2 miles and 1 2/3 hours how far can she walk in four hours?
Answer:
Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.
Step-by-step explanation:
Given that:
Distance walked by Miley in [tex]1\frac{2}{3}[/tex] hours = [tex]5\frac{1}{2}[/tex] miles
We will find unit rate in term of hours.
[tex]\frac{5}{3}\ hours = \frac{11}{2}\ miles[/tex]
Multiplying both sides by 3/5
[tex]\frac{3}{5}*\frac{5}{3}\ hour = \frac{11}{2}*\frac{3}{5}\\\\Unit\ rate = \frac{33}{10}\miles\ per\ hour[/tex]
Distance walked in four hours = [tex]4*\frac{33}{10}\ miles[/tex]
Distance walked in 4 hours = [tex]\frac{66}{5}=13\frac{1}{5}\ miles[/tex]
Hence,
Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

Answer:
7. Inscribed angle
Step-by-step explanation:
7. Inscribed angle
8.
y° = 70°
z° = 140°
8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.
Therefore, y° = 70°
Measure of central angle is two times the measure of the inscribed angle.
Therefore,
z° = 2* 70° = 140°
The random variable X has mean 12 and standard deviation 3. The random variable W is defined as W = 7+2X. What are the mean and standard deviation of W?
A. The mean is 24, and the standard deviation is 6.
B. The mean is 24, and the standard deviation is 13.
C. The mean is 31, and the standard deviation is 3.
D. The mean is 31, and the standard deviation is 6.
E. The mean is 31, and the standard deviation is 13.
Answer:
Mean=X=12
SD=3
W=7+2X
Mean(W)=7+2Mean(X)
Mean(W)=7+2(12)
=7+24=31
SD(W)=2SD(X)
SD(W)=2(3)=6
