[tex] \frac{2}{5}x = \frac{7}{20}x + \frac{1}{4} [/tex]
[tex] -\frac{3}{4} = -\frac{1}{20}x - \frac{1}{2} [/tex]
Step-by-step explanation:
Given,
[tex] -\frac{3}{4} + \frac{2}{5}x = \frac{7}{20}x - \frac{1}{2} [/tex]
There are two possible ways to start solving for the value of x.
✔️The first is, add both sides by ¾
[tex] -\frac{3}{4} + \frac{2}{5}x + \frac{3}{4} = \frac{7}{20}x - \frac{1}{2} + \frac{3}{4} [/tex]
[tex] \frac{2}{5}x = \frac{7}{20}x + \frac{1}{4} [/tex] (-½ + ¾ = ¼)
This equation represents the first possible way to begin with.
✔️The second is subtract both sides by ⅖x
[tex] -\frac{3}{4} + \frac{2}{5}x - \frac{2}{5}x = \frac{7}{20}x - \frac{1}{2} - \frac{2}{5} [/tex]
[tex] -\frac{3}{4} = \frac{7}{20}x - \frac{2}{5}x - \frac{1}{2} [/tex]
[tex] -\frac{3}{4} = \frac{7 - 8}{20}x - \frac{1}{2} [/tex]
[tex] -\frac{3}{4} = -\frac{1}{20}x - \frac{1}{2} [/tex]
This equation represents another way to start.

At the beginning of last year,there were 368 students at the elementary school.By the beginning of this year,72 of those students have moved to other school districts and 64 new students arrived. about how many students started the school year this year
Answers
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.

Answer:
[tex]\displaystyle a_n=100+10(n-1)[/tex]
[tex]\displaystyle a_{10}=190[/tex]
Step-by-step explanation:
We have the arithmetic sequence:
100, 110, 120, 130...
And we want to determine the equation for the nth term of the sequence.
The standard form for the nth term of an arithmetic sequence is given by the formula:
[tex]\displaystyle a_n=a+d(n-1)[/tex]
Where [tex]a_n[/tex] is the nth term, [tex]a[/tex] is the first term, and [tex]d[/tex] is our common difference.
From the sequence, we can see that the first term [tex]a[/tex] is 100.
Also, each term is +10 the previous term. Hence, our common difference [tex]\displaystyle d[/tex] is +10.
Therefore, our equation is:
[tex]\displaystyle a_n=100+10(n-1)[/tex]
To find the 10th term, we can substitute 10 for n and evaluate. Hence:
[tex]\displaystyle a_{10}=100+10(10-1)[/tex]
Evaluate:
[tex]\displaystyle a_{10}=100+10(9)=100+90=190[/tex]
Therefore, the 10th term is 190.

Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to 25
7
She writes the equation Y = X+ 25. What error is Roni making?
7
She should have written Y =-X+ 25 so that x and y have a constant sum.
7
She should have written XY - 25 so that x and y have a constant product.
7
She should have written Y = 25% so that x and y have a constant quotient.
7
She should have written Y = 25 so that y has a constant value
Answers
Answer:
She should have written Y = 25X
Step-by-step explanation:
We are told that Roni writes the equation Y = X + 25.
Now, since she wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to 25, it means that she shouldn't have added 25 to X but instead multiply it with X to get;
Y = 25X

Answer: The second description is correct for the absolute value of x

Step-by-step explanation: breaking it down:
A number line is shown from negative 6 to positive 6 with increments of 1. All the numbers are labeled on the number line. The first part is the same in all of the descriptions
A dot is shown on a point at 6 tick marks to the left of 0. This represents -6 on the number line.
Above the number line, a bracket is shown extending from a point at 6 tick marks to the left of zero to 0. This shows the distance between 0 and -6. Important. Absolute value is the distance between two numbers
A horizontal line is shown between the brackets, This is the measuring line 6 units long.
and 6 is written on the line. Important. It is a plain number, no negative or positive! Absolute value is just that.

[tex]y - 5 = \frac{1}{3}(x+2)[/tex]
Step-by-step explanation:
Point-slope form: y- y1 = m(x - x1)
Given:
Slope(m) = [tex]\frac{1}{3}[/tex]
Point(x1, y1): (-2, 5)
To write the equation in point-slope form, input the given values of the point and slope into the equation format:
y - y1 = m(x - x1)
[tex]y - 5 = \frac{1}{3} (x-(-2))[/tex]
[tex]y - 5 = \frac{1}{3} (x+2)[/tex]
The equation in point slope form is: [tex]y - 5 = \frac{1}{3} (x+2)[/tex]

someone pls help me with this :(
Answers
Answer:
y=Mx+c. you can just look at the gradient the m of the graphs. If the m is positive it means the graph is going up, if the m is negative, the line goes downwards. As for the value of m, it just means how steep the line is. Let's say you're going up a hill that has an m of 10, it would be wayy steeper and you'd be very tired than if the m were 1. So the 2x has the largest m in your question which is 2, so out of the four graphs, graph number 1 is the steepest and it's positive, which goes up.
two alarms are set to go off in the morning. one alarm will buzz every 6 minutes and the other will beep every 9 minutes. if both alarms go off 6:15 am what is the next time the both alarms will go off at the same time
Answers
=========================================================
Explanation:
The LCM of 6 and 9 is 18. We can see that by listing out the multiples
multiples of 6 = {6,12,18,24,30,...}
multiples of 9 = {9,18,27,36,45...}
Or we could multiply 9*6 = 54, and divide by the GCF 3 getting 54/3 = 18. There are a few options to find the LCM.
The LCM being 18 means that every 18 minutes, both alarms will go off. If they both sound off at 6:15 AM, then the next time they trigger together is 6:33 AM since 15+18 = 33, and there is no carry over to the next hour.
You can think of the time values adding like this
6:15 + 0:18 = (6+0):(15+18) = 6:33
