Answer:
The expression has a variable with a coefficient (constant) and a constant. Therefore, to create a new expression with 2 terms, take out a constant and use parentheses:
The most obvious number to take out is either 2 or 3 since those are the constants in the expression:
Taking out the constant 3:
[tex]2x-3= 3\left(\dfrac23x-1\right)[/tex]
or taking out the constant 2:
[tex]2x-3= 2\left(x-\dfrac32\right)[/tex]
However, you can choose to take out any value, as long as it's a number and not a variable:
[tex]2x-3= \dfrac12\left(4x-6\right)[/tex]
[tex]2x-3= \dfrac14\left(8x-12\right)[/tex]
To check that it is equivalent, expand the brackets.
Evaluate the expression when a=4, b=15, and c= 16.

Factor Completely: 10x + 15
Answer:
5(2x + 3)
Step-by-step explanation:
[tex]10x + 15 \\ \\ = 2 \times 5 \times x + 3 \times 5 \\ ( take \: common \: factors \: out )\\ = 5(2 \times x + 3) \\ \\ = 5(2x + 3)[/tex]

Min-jun weighs 191 pounds and plans on losing 4.9 pounds each month. Ahab weighs 216 pounds and plans on losing 6.2 pounds per month. If they stick with their plans, how many months will it take Ahab to weigh the same as Min-jun? Write an equation to represent this situation. Use x as the variable. Find the number of months provide an answer accurate to the nearest month
Answer:
if i did my math right it should be 216-(6.2*x) 191-(4.9*x)
Step-by-step explanation:
216-(6.2*x) 191-(4.9*x) and if you go up the line from 0 from the first and second equation you will end up at 8 and 5 so Ahab will have to stick to his plans for 8 months/but if it means how much if he needs to reach near or exactly 191 pounds then it would be only 216-(6.2*x) for the equation and the answer would be 4 months

Step-by-step explanation:
Solve for y.
6 = 2 (y+2)
y = ___
y=1!!!!!!!!!!!!!!!!!!!
Answer:
[tex]y=1[/tex]
Step-by-step explanation:
Given the following question:
[tex]6=2(y+2)[/tex]
In order to find the answer, we will rewrite the equation by switching the sides and then solve by dividing on both sides.
[tex]6=2(y+2)[/tex]
[tex]2\left(y+2\right)=6[/tex]
[tex]\frac{2(y+2)}{2} =y+2[/tex]
[tex]6\div2=3[/tex]
[tex]y+2=3[/tex]
[tex]2-2=0[/tex]
[tex]3-2=1[/tex]
[tex]y=1[/tex]

Step-by-step explanation:

20y + 2 + 3
20y + 5
Have an amazing day!
PLEASE MARK BRAINLIEST!
Answer:
Added Like Terms: 20y + 5
Equivalent Expression: 12y + 8y + 4 + 1
Explained:
Add like terms. Both 6y and 14y have a variable of y, so they can be added.
6y + 14y = 20y
Next, add the next set of like terms. 2 and 3 both don't have a variable, so you can add em'.
2 + 3 = 5
There are no more like terms to add since 20y has a variable and 5 doesn't, leaving you with the answer 20y + 5.
As for the equivalent expression, I just created another expression that equals 20y + 5.

URGENT I NEED HELP ANSWERING THESE
I can only answer 5, use my answer to help find 6.
Answer:
The volume is 259,824,773,000
Step-by-step explanation:
r, or radius is half of the diameter. So we are left with (4 * pi (also known as 3.14159)* 3958.5^3)/3
(7.7947432 * 10 ^ 11) / 3 = 779,474,320,000 / 3
Which is equal to 259,824,773,000 as the volume.
I hope this solves 5 and helps you with 6.

_____________________________
Answer:
0.22
Step-by-step explanation:
To find the experimental probability, we first find the total amount of responses and then divide it by the number of responses going to city A. The total is 100, and the number of responses going to city A is 22.
Now divide the number of responses of going to city A by the total.
Experimental probability = 22/100, or 0.22
I don't know if this is the right answer, but I hope this helps.

Answer:
(x=9)
largest angle= 8x+8(ans=80)
Step-by-step explanation:
first of all we need to find x
we write this as an equation
8x+8+5x-1+5x+11=180
18x+18=180
18x=180-18
18x=162
x=162/18
x=9
Now the question is to find the largest angle
so
we just find the orginal value for all the angles by replacing the x with 9
1. 8x + 8
= 8x9+8
= 80
2. 5x - 1
= 5 x 9 - 1
= 44
3. 5x+11
= 5 x 9 + 11
= 56
Hence the largest angle is 80 ( 8x+8)
Hope this helped.

rates form a proportion? Explain.
These both rates are not proportional because if 8 mile in 10 minutes and 20 miles in 30 minutes .. So 10 times 3 equals 30 minutes but if we multiply 8 times 3 is equal to 24. So there are not proportional.. I hope this helped

First, we need to work with parenthese. Rembering "Pemdas"
Multiply 7 and 8 to get 56.
56y− 2x/5
To add or subtract expressions, expand them to make their denominators the same. Multiply 56y times 5/5
5x56y
------------ -2x/5
5
Since 5x56y over 5 and 2x over 5 have the same denominator, subtract them by subtracting their numerators.
5 x 56y -2x over 5
Do the multiplications in 5×56y−2x.

A runner completed a 26.2-mile marathon in 210 minutes.Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth of a minute.
Answer:
The unit rate in minutes per miles be 8.02 minutes per miles .
Step-by-step explanation:
Step 1. 26.2 miles/ 210 mins = x miles / 1min
1 * 26.2 / 210 = .12 miles / min
Step 2. 26.2. 0.13
÷210.
210. 1
(The amount miles ran in 1 minute is 0.13 miles.)
Step 3. 26.2/210= .125 miles per minute
210/26.2= 8.02 minutes per mile
Step 4. 1) Cross multiply. (26.2 = 210x)
2) Divide 210 from each side. (26.2/210 = .1247619048 , 210x/210 = x)
3) Round to the nearest 100th. (.12)
4) X=.12
5) .12 miles ran per minute

Answer:
Middle School In Favor: 25%
Middle School Not in Favor: 75%
High School In Favor 20%
High School Not In Favor 80%
Step-by-step explanation:
For the middle school in favor, we need to find the percent, which is 50 out of 200, so its 1/4, 25%
So the rest of the middle school is not in favor, which is 75%
High school is 60 not in favor, so we need to find the percentage. So 60 out is 300 is 20%
And we just subtract 20 from 100 which leaves us with 80
