2(x-2)+3(x+1)=9
2(x - 2) + 3(x + 1) = 9
2x - 4 + 3x + 3 = 9 distributed the 2 and 3 on the left side
5x - 1 = 9 added like terms (2x + 3x) and (-4 + 3)
5x = 10 added 1 to both sides
x = 2 divided 5 from both sides

Answer:
-13F is less than -12F, and -9F is greater than -12F
Step-by-step explanation:
You can prove this because in the problem is states that -13F < -12F < -9F
If you utilize this, you find that the first statement is quite obvious:
-13F is less than -12F
The second statement is a little trickier. Since in the original inequality is states that -12F < -9F, but you want to know the relationship between the switch, you would just flip the sign in the middle, getting you:
-9F is greater than -12F
You could also prove this simply with the rules of negative values (which work inversely from positives).

As in the first four terms, I assume that means using the equation with 1,2,3,4.
11) if n = 1, the answer would be 3.
If n = 2, the answer would be 10.
If n = 3, the answer would be 17.
If n = 4, the answer would be 24.
12) If n = 1, the answer would be 55.
If n = 2, the answer would be 45.
If n = 3, the answer would be 35.
If n = 4, the answer would be 25.
An explicit formula is used to find any term in a sequence by putting in the number of that term in place of the unknown variable.
In order to find the first four terms, we need to plug values, from 1-4, separately in each of the formulas.
For f(n) = 7(n+1) - 11, put values from 1-4 in place of n:
f(1) = 7(1+1) - 11 = 3 ----> First term
f(2) = 7(2+1) - 11 = 10 ----> Second term
f(3) = 7(3+1) - 11 = 17 ----> Third term
f(4) = 7(4+1) - 11 = 24 ----> Fourth term
For f(n) = 65 - 10n, put values from 1-4 in place of n:
f(1) = 65 - 10(1) = 55 ----> First term
f(2) = 65 - 10(2) = 45 ----> Second term
f(3) = 65 - 10(3) = 35 ----> Third term
f(4) = 65 - 10(4) = 25 ----> Fourth term

A dance school allows a maximum of 15 students per class. If 112 students sing up for dance class, how many classes does the school need to offer to accommodate all the students?
The answer is 8.
In order to accommodate (or provide space for) all students, with the maximum students per class being 15, there needs to be at least enough for 112. A way to figure this out is 112 / 15 (the total amount of people signed up divided by the amount per class). The quotient is 7.466..., which does not work since you cannot have a 0.466... of a human in a class. This means you must round to the nearest whole number. If there were more students it could accommodate 8 more being that 15 * 8 is 120, but in this case there are only 112.

A fish tank that holds 80 gallons of water is 55 % full. how many gallons are in the tank now?
Answer:
[tex]44\ gallons[/tex]
Step-by-step explanation:
we know that
A fish tank holds [tex]80[/tex] gallons of water
so
By proportion
Find how many gallons represent [tex]55\%[/tex] of the total tank capacity.
[tex]\frac{80}{100}\frac{gallons}{\%} = \frac{x}{55}\frac{gallons}{\%}\\ \\x=55*80/100\\x= 44\ gallons[/tex]
There are 44 gallons of water in the tank. This is calculated by converting the percentage full into a decimal (0.55) and multiplying it by the total capacity of the tank (80 gallons).
Explanation:The question is asking how many gallons are currently in the fish tank that is 55% full and has a total capacity of 80 gallons.
First, you need to convert the percentage of the tank that is full (55%) to a decimal. To do this, you divide the percentage by 100.
So, 55 divided by 100 equals 0.55.
Next, you multiply this decimal by the total capacity of the tank to find out how many gallons are currently in the tank. 0.55 times 80 equals 44. Therefore, there are 44 gallons of water in the fish tank now.

At a school concert,the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others.how long is the concert?
Answer: 59.5 minutes.
Step-by-step explanation:
1. You have the following information given in the problem above:
- 8 songs are 4.25 minutes long.
- 3 songs are twice as long as each of the others.
2. Therefore, the total time of 8 songs is:
[tex](8)(4.25min)=34min[/tex]
3. And the total time of the 3 songs is:
[tex](2)(3)(4.25min)=25.5min[/tex]
4. Therefore, you have that the result is:
[tex]34min+25.5min=59.5min[/tex]
The concert is 59.5 minutes long.
Let's break down the problem step-by-step:
The orchestra plays 8 songs that are each 4.25 minutes long.The orchestra also plays 3 songs that are twice as long as each of the 4.25 minute songs.First, we calculate the total time for the 8 songs:8 songs x 4.25 minutes = 34 minutes
Next, we calculate the length of the songs that are twice as long as the 4.25 minute songs:2 x 4.25 minutes = 8.5 minutes per song
We then find the total time for these 3 songs:3 songs x 8.5 minutes = 25.5 minutes
Finally, we add the time for all the songs to get the total duration of the concert:34 minutes + 25.5 minutes = 59.5 minutes
So, the total duration of the concert is 59.5 minutes.
the sum of 367 and 863 is equal to the sum of 863 and another number. what is that number?
Answer:
Sum of 367 and 863 is equal to the sum of 863 and 367. Thus, 367 is the required number.
Step-by-step explanation:
Commutative property of Addition
Let a and b be two real numbers. Then commutative property of addition states that the sum of a and b is equal to the sum of b and a that is
[tex]a + b = b + a[/tex]
Similarly, we a re given here,
[tex]367 + 863 = 1230\\1230 = 863 + 367[/tex]
Thus, sum of 367 and 863 is equal to the sum of 863 and 367.
Thus, 367 is the required number.

Dion is at a basketball game and he wants to buy some hamburgers and drinks. His friend joe brought 2 Hamburgers and 5 drinks for $8.00 and Felicia brought 2 hamburgers and 3 drinks for $6.00. Help Dion determine the cost of one hamburger and one drink
For this one, the best way to do it is write out you formulas, then solve for the first one and see if it works for the second one.
I am going to use h for hamburgers and d for drinks to make it easier.
2h+5d=8
2h+3d=6
So what I did was make the drinks 1, this way you can see if you need to raise it or if the hamburgers could come out even. When you do that here is what it looks like:
2h+5(1)=8
2h+5=8
2h=3
h=1.50
So here is what you have as of now
h= 1.50 and d= 1
now plug that into the next problem
2h+3d=6
2(1.50)+3(1)=6
3+3=6
So that is your answer
Hamburgers are $1.50
and Drinks are $1
Hope this helps!
Hamburgers cost 1.50 each and its 1.00 for each drink
Two questions plz help asap. 1.what is the value of a? [tex]-2(a - 8) + 6a = 36[/tex] 2. whats the value of n[tex]\frac{3n + 6}{3} = 15[/tex]
1. What is the value of a?
-2(a - 8) + 6a = 36
Remember to follow PEMDAS. First, distribute -2 to all terms within the parenthesis
-2(a - 8) = -2a + 16
-2a + 16 + 6a = 36
Simplify. Combine like terms
6a - 2a = 4a
4a + 16 = 36
Isolate the a. Do the opposite of PEMDAS. First, note the equal sign. What you do to one side, you do to the other.
Subtract 16 from both sides
4a + 16 (-16) = 36 (-16)
4a = 36 - 16
4a = 20
Divide 4 from both sides
4a/4 = 20/4
a = 20/4
a = 5
5 is your answer for a
-------------------------------------------------------------------------------------------------------------------
2. What is the value of n in (3n + 6)/3 = 15
Remember to do the opposite of PEMDAS. Note the equal sign. First, multiply 3 to both sides
(3n + 6)/3(3) = 15(3)
3n + 6 = 45
Next, subtract 6 from both sides
3n + 6 (-6) = 45 (-6)
3n = 45 - 6
3n = 39
Finally, isolate the n. Divide 3 from both sides
3n/3 = 39/3
n = 39/3
n = 13
13 is your answer for n

Look at the equation below.
M = 4G − z
Which of the following is the same equation solved for G?
A. G = M+z/4
B. G = 1/4 M + z
C. G = 4M + z
D. G = 4(M − z)
By isolating 'G' in the given equation, 'M = 4G - z', we find that 'G' is equal to '(M + z) / 4', which matches with choice A in the question.
Explanation:The given equation is M = 4G - z. To solve this equation for G, we should first move 'z' over to the other side of the equation, which will give us M + z = 4G. In the next step, we divide each side of the equation by 4 to isolate 'G'. Our answer is then G = (M + z) / 4. This is equivalent to the choice A. G = M+z/4 given in the original question.
