9m-4=-3m+5+12m how do you solve this equation
Answer:
Step-by-step explanation:
9m-4 = -3m + 5 + 12m
-9m -9m
-4= -3m + 5 + 12m - 9m
-5 -5
-9 = m
i believe
To solve the equation, simplify both sides and combine like terms. Subtract 9m from both sides to isolate the variable. There is no solution to this equation.
Explanation:To solve the equation 9m-4=-3m+5+12m, we need to simplify both sides and combine like terms.
Starting with the left side, we have 9m-4. On the right side, we have -3m+5+12m. Combining like terms on both sides, we get 9m-4=9m+5. We can then subtract 9m from both sides to isolate the variable, giving us -4=5.
Since -4 is not equal to 5, there is no solution to this equation.

The length of a diagonal of a quadrilateral shaped field Is 48 m And the length of perpendicular dropped on it from the remaining apposite vertices are 16 m and 26 m find the area of the field
Answer:
[tex]1008\text{ m}^2[/tex]
Step by step explanation:
Please find the attachment.
We have been given that the length of a diagonal of a quadrilateral shaped field Is 48 m. The length of perpendicular dropped on it from the remaining apposite vertices are 16 m and 26 m.
We can see from our attachment that diagonal AC divides our quadrilateral field into two triangular fields and AC will be the base of both triangles.
To find the area of our given quadrilateral we will find the areas of both triangles and add the areas.
Let us find area of triangle ABC with base 48 m and height 26 m.
[tex]\text{Area of triangle}=\frac{1}{2}(\text{ Base}\times\text{ Height})[/tex]
[tex]\text{Area of triangle ABC}=\frac{1}{2}\times 48\times 26[/tex]
[tex]\text{Area of triangle ABC}=24\times 26[/tex]
[tex]\text{Area of triangle ABC}=624[/tex]
Therefore, the area of triangle ABC will be 624 square meters.
Now let us find area of triangle ADC with base 48 m and height 16 m.
[tex]\text{Area of triangle ADC}=\frac{1}{2}\times 48\times 16[/tex]
[tex]\text{Area of triangle ADC}=24\times 16[/tex]
[tex]\text{Area of triangle ADC}=384[/tex]
Therefore, the area of triangle ADC will be 384 square meters.
Now let us add areas of triangles ABC and ADC to get the area of our quadrilateral ABCD.
[tex]\text{Area of quadrilateral ABCD}=384+624[/tex]
[tex]\text{Area of quadrilateral ABCD}=1008[/tex]
Therefore, the area of quadrilateral shaped field will be 1008 square meters.

Which coefficient before hydrogen (H2) balances this chemical equation? N2 + __H2 2NH3 A. 2 B. 3 C. 4 D. 5
Answer:
Step-by-step explanation:
The answer to this question is 3
Hope this helps
To balance the chemical equation N2 + __H2 -> 2NH3, we need to have the same number of each type of atom on both sides. We have 2 Nitrogen atoms on each side of the equation, but the Hydrogen atoms are unbalanced. By placing a coefficient of 3 before H2, we get a balanced chemical equation; N2 + 3H2 -> 2NH3. Hence, the correct answer is option B, 3.
Explanation:In order to balance a chemical equation, the same number of each type of atom must be present on both sides of the equation. In the initial chemical equation given, N2 + __H2 -> 2NH3, we have 2 Nitrogen atoms on both sides which is balanced. However, for Hydrogen we have 2 Hydrogen atoms on the left side (from H2) but 6 on the right side (as each NH3 molecule has 3 Hydrogen atoms). Therefore, we need to balance the Hydrogen atoms.
Putting a coefficient of 3 before H2 on the left side of the equation, we will have 3 * 2 = 6 Hydrogen atoms. This balances the Hydrogen atoms on both sides of the equation. Hence, the balanced chemical equation becomes N2 + 3H2 -> 2NH3. Therefore, the correct answer is B. 3.

Which polygon has interior angles whose sum is 1440°? octagon nonagon decagon 11-gon
Answer:
Decagon
Step-by-step explanation:
We can use the general equation to determine the sum of interior angles:
[tex]I.A. = 180 \times (n-2)[/tex]
Since we know the sum of interior angles (I.A.) is 1440°, we must figure out n - the number of sides and so:
[tex]1440=180(n-2)\\\\\frac{1440}{180}=n-2\\\\8=n-2\\\\n=10[/tex]
Since n=10 this means that it is a 10 sided shape meaning it's a decagon.
Answer:
decagon
Step-by-step explanation:
1440=180(n-2)
8=n-n
n=10
this means that your answer is going to is decagon.
The equation y = 11x describes the amount of money Louis earns, where x is the number of hours he works and y is the amount of money he earns. The table shows the amount of money Carl earns for different numbers of hours worked. Carl’s Earnings
Time (h) 3 5 8 10
Money earned ($) 42 70 112 140
(a) How much money does Carl earn per hour? Show your work.
(b) Who earns more per hour? Justify your answer.
(c) Draw a graph that represents Carl’s earnings over time in hours.
Label the axes
Answer:
Step-by-step explanation:
(a) Carl earns $42 per 3 hours as given. To find the amount he earns per hourdivide:
$42/3 hours = $14/hour
(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:
y = $11(1 hours)
y = $11/hour
Thus Carl makes more than Louis.
(c) The equation of Carl's dollars per hour is similar to Louis' = 14x
where x is the number of hours he works and y is the number of dollars he earns. Plug in whole number values of hours for x and plot the points (x, y) on a graph
Is him in your bias?
Carl earns $14 per hour, which is more than Louis' hourly wage of $11. A graph that represents Carl's earnings should have time in hours on the x-axis and money earned on the y-axis.
The question relates to comparing Hourly Earnings of Louis and Carl, and analyzing earnings overtime through graphs.
(a) To determine Carl's hourly earnings, we divide the amount of money earned by the hours worked.
For example, when he works 3 hours, he earns $42.
Therefore, the hourly rate is $42/3 = $14 per hour.
(b) By comparing Carl's hourly earning which is $14/hour to Louis' earning which is $11/hour according to the equation y = 11x, it is clear that Carl earns more per hour.
(c) To plot the graph for Carl's earnings, you need to put the time in hours on the x-axis and the money earned on the y-axis.
Each point on the graph represents the amount Carl earns after a certain number of hours.
For example the point (3,42) represents that Carl earns $42 after 3 hours of work.

The freshman class at Central High totals 522 students, with 100 more girls than boys. Which equation can be used to find the number of boys?
Answer:
The required equation is (1) and the number of boys is 211.
Step-by-step explanation:
Let the number of boys be x.
It is given that there are 100 more girls than boys. It means the number of girls is x+100.
The total number of students is 522.
Number of boys + Number of girls = 522
[tex]x+(x+100)=522[/tex] ... (1)
Combine like terms.
[tex]2x+100=522[/tex]
Subtract 100 from both the sides.
[tex]2x+100-100=522-100[/tex]
[tex]2x=422[/tex]
Divide both sides by 2.
[tex]x=211[/tex]
Therefore the required equation is (1) and the number of boys is 211.
Answer:
[tex]2x+100=522[/tex]
Step-by-step explanation:
Let the no. of boys be x
We are given that there are 100 more girls than boys.
So, No. of girls = x+100
Total number students = [tex]x+x+100[/tex]
= [tex]2x+100[/tex]
We are given that The freshman class at Central High totals 522 students
So, equation becomes : [tex]2x+100=522[/tex]
Hence an equation can be used to find the number of boys is [tex]2x+100=522[/tex]

3.25+0.5x+1 1/3 + 5/6 x=5 11/12
what is x?
PLZ HELP DUE SOON
Answer: x = 0
Step-by-step explanation:
The first step would be to convert everything to one form. I'll do the fractions, since 1/3 is hard to represent in decimal.
3 1/4 + 1/2x + 1 1/3 + 5/6x = 5 11/12
Now, the fractions will be converted via GCF. 12 is easily divisible by 4, 2, 3 and 6, so that I'll be the denominator used.
3 1/4 -> 3 3/12
1/2x -> 6/12x
1 1/3 -> 1 4/12
5/6x -> 10/12x
5 11/12 will stay the same.
The new equation is:
3 3/12 + 6/12x + 1 4/12 + 10/12x = 5 11/12
Combine like terms:
4 7/12 + 1 4/12x = 5 11/12
Subtract 4 7/12 from both sides
1 4/12x = 1 4/12
Divide both sides by 1 4/12x
