Answer:
wat number put the value there
The required sum of the number m and the number after it 2m + 1.
Given that,
To determine the sum of the number m and the number after it.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Let the number m and the number after m is m+1
Now the sum = m + m + 1
= 2m + 1
Thus, the required sum of the number m and the number after it 2m + 1.

whats 2/3x+3/7=1-4/7x
Answer:
[tex]x=6/13[/tex]
Step-by-step explanation:
So we have:
[tex]\frac{2}{3}x+\frac{3}{7}=1-\frac{4}{7}x[/tex]
Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.
The denominators are 3 and 7.
The LCM of 3 and 7 is 21. Thus, multiply everything by 21:
[tex]21(\frac{2}{3}x+\frac{3}{7})=21(1-\frac{4}{7}x)[/tex]
Distribute:
[tex]\frac{42}{3}x+\frac{63}{7}=21-\frac{84}{7}x[/tex]
Simplify the fractions:
[tex]14x+9=21-12x[/tex]
Add 12x to both sides:
[tex]26x+9=21[/tex]
Subtract 9 from both sides:
[tex]26x=12[/tex]
Divide both sides by 26:
[tex]x=12/26[/tex]
Reduce:
[tex]x=6/13[/tex]
And that's our answer :)
Answer: x = 6/13
find the common denominator (21);
14/21x + 9/21 = 21/21 - 12/21x
move your variable to one side and your constants to the other:
26/21x = 12/21
multiply all by 21/26 to get a lone x:
x = 12/26
simplify:
x = 6/13

can someone help me write a conclusion paragraph? i wrote an essay on why masks and social distancing were effective and I can't think of what to write for my conclusion. please help me!
Answer:
Step-by-step explanation:
A conclusion is 2-3 closing sentences to wrap up your essay. You should start with a transition word, like "To conclude," and then state your controlling idea. Or, the reason why you are writing this essay. Then, you need to end with a closing sentence, which is pretty hard to do. This can be a question or a statement. If you pick a question, then you need to say something like this:
Why do you think masks and social distancing are effective during these hard times?
If you pick a statement, then it needs to end something like this:
I wonder....
Now, I am going to let you figure this out, because people should learn. Good luck and I hope this helps!
gabrielle took a spanish test with 50 questions and answered 44 of then correctly. what percent of the questions did gabrielle answer correctly?
Answer:88%
Step-by-step explanation:
Percent means out of hundred. If you try to find what percentage something is out of a larger number, you multiply the fraction by 100%.
Our fraction in this case is 44/50.
(44/50) × 100% simplifies to (using a common factor of 2) (22/25) × 100% (2 goes into 44 twenty-two times, and into 50 twenty-five times). 100 and 25 share a common factor of 25, so this fraction can further be simplified to (22/1) × 4% (25 goes into itself once, and into 100 four times). 22/1 is the same as 22. 22 × 4% = 88%. And that's your answer.
I NEED THIS ANSWER BY TONIGHT!!!! How many gallons of a 90% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 80% antifreeze? Use the six-step method.
Answer:
Solution : 600 gallons
Step-by-step explanation:
Let's say that x is the gallons of 90% antifreeze solution. Let's start by converting each percent to decimal form.
90% = 0.9
20% = 0.2
80% = 0.8
Knowing that we have the following set up,
0.9(x) + 0.2(100) = 0.8(x + 100) ⇒ 0.8 is associated with " x + 100 " as it is a mixture of the gallons of the 90% antifreeze solution, and the gallons of the 20% antifreeze solution
We can solve for x in this equation, and receive our solution. This is represented by the following attachment. It proves that there are 600 gallons of the 90% antifreeze solution.

It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?
Answer:
22 minutes
Step-by-step explanation:
The number of minutes and number of people are inversely proportional but the number of people, minutes painted and walls painted are directly proportional. Therefore, it takes 10 people 22 / 10 = 2.2 minutes to paint 1 wall and 2.2 * 14 = 30.8 minutes to paint 14 walls. To find the time it takes 14 people to paint 14 walls, we can set up the following equation:
14 * x = 30.8 * 10 (where x is our answer)
x = 30.8 * 10 / 14 = 22 minutes
Additionally, an easier way to do this is to recognize that 1 person paints 1 wall when 10 people paint 10 walls in 22 minutes so as long as the number of people and walls are the same, it will always take 22 minutes.

3х – 13 = 23
Please give an explanation to the answer
Answer:
x = 12
Step-by-step explanation:
3x - 13 = 23
Bring non-variable numbers to other side:
3x = 36
Divide both sides by 3:
x = 12
Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.

Find an equation of the line that passes through the given point and has the indicated slope m.
Answer:
y = [tex]\frac{4}{5}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{4}{5}[/tex] , thus
y = [tex]\frac{4}{5}[/tex] x + c ← is the partial equation
To find c substitute (- 5, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = [tex]\frac{4}{5}[/tex] x + 2 ← equation of line in slope- intercept form

the perimeter of a rectangle is 44 cm.if its length is increased by 4 cm and breadth is increased by 2 cm its area is increased by 72 sqcm. find the dimensions of the rectangle
Answer:
11 cm, 11 cm
Step-by-step explanation:
Let the length and width of the rectangle be x cm and y cm respectively.
Therefore,
Perimeter of rectangle = 44 cm
2(x + y) = 44
x + y = 44/2
x + y = 22...... (1)
Area of rectangle = xy
When length is increased by 4 cm and breadth is increased by 2 cm.
New length = (x + 4) cm
New width = (y + 2) cm
New area of rectangle = original area + 72.. (given)
Therefore,
(x + 4) (y + 2) = xy + 72
xy + 2x + 4y + 8 = xy + 72
2x + 4y = 72 - 8
2x + 4y = 66
2(x + 2y) = 66
x + 2y = 66/2
x + 2y = 33.... (2)
Subtracting equation (1) from equation (2)
x + 2y - (x + y) = 33 - 22
x + 2y - x - y = 11
y = 11
Substituting y = 11 in equation (1)
x + 11 = 22
x = 22 - 11
x = 11
Thus, the dimensions of the rectangle are 11 cm and 11 cm.

Solve for x. 7/8(−32−48x)+36 =2/3(−33x−18)−10x
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2
Answer:
x=2
Step-by-step explanation:
7/8(-32)-7/8(48x)+36=2/3(-33x)-2/3(18)-10x
= -224/8-336x/8+36
=-66x/3-36/3-10x.
Simplifying the fractions
-28-42x+36=-22x-12-10x.
Combining like terms
-42x+8=-32x-12.
Add 32x to both sides:
-42x+8+32x=-32x-12+32x
-10x+8=-12.
Subtract 8 from both sides:
-10x+8-8=-12-8
-10x=-20.
Divide both sides by -10:
-10x/-10 = -20/-10
x=2.
