Answer: x=15
Step-by-step explanation:
x/3+1= 6
Step 1: Subtract 1 from both sides (always do inverse operations with the number, not the x term(s))
x/3 + 1-1 = 6-1
x/3= 5
Step 2: Now we need to isolate x (get it on its own). To do this, we must move the 3 to the other side, which we will do by multiplying the 3 and the 5 (as since the 3 was used for divisision, its inverse operation is multiplication).
x/3 = 5
x = 5x3
x= 15
Step 3: Check by using PITA, or "Plugging In the Answers"
We came to the conclusion that x=15. Now, we can "plug in", or substitute the x in the equation for 15:
x/3 + 1= 6
15/3 + 1= 6
5+ 1= 6
6=6
Correct ✔️
Answer:
X = 24
Step-by-step explanation:
3 + 1 = 4
X/4 = 6
Multiply both sides by 4
X = 24

(Will l give 25 points!) Solve the system of linear equations by substitution. -8x + y = 5 and 5x - y = 3
Answer:
x = -8/3 and y = -49/3
Step-by-step explanation:
(Step 1) To solve using substitution, you first need to isolate a variable in one of these equations. I chose to isolate "y" in the following equation.
-8x + y = 5 <--- Original equation
y = 5 + 8x <--- Add 8x to both sides
(Step 2) Now, substitute (5 + 8x) for "y" in the second equation.
5x - y = 3 <--- Original equation
5x - (5 + 8x) = 3 <--- Substitute 5 + 8x for "y"
5x - 5 - 8x = 3 <--- Distribute (-) in the parentheses
-3x - 5 = 3 <--- Combine terms with "x"
-3x = 8 <--- Add 5 to both sides
x = -8/3 <--- Divide both sides by -3
(Step 3) Since you know the value of "x", plug it into one of the equations to solve for "y".
y = 5 + 8x <--- Original (rearranged) equation
y = 5 + 8(-8/3) <--- Plug (-8/3) for "x"
y = 5 - 64/3 <--- Multiply
y = 15/3 - 64/3 <--- Convert 5 into a fraction
y = -49/3 <--- Subtract
(Step 3.5) You can check your work by plugging "y" into the other equation to see if the answer for "x" is the same.
5x - y = 3 <--- Original equation
5(-8/3) - y = 3 <--- Plug (-8/3) for "x"
-40/3 - y = 3 <--- Multiply
-40/3 - y = 9/3 <--- Convert 3 into a fraction
-49/3 - y = 0 <--- Subtract both sides by 9/3
-49/3 = y <--- Add both sides by "y"
The value of the system of equations is x = -8/3 and y = -49/3.

A teacher would like to estimate the percentage of her students who play chess.
Which method should the teacher use to select the sample?
A. select all students who are currently in the chess club
B. use a computer to randomly select 30 student IDs from all her students
C. use a computer to randomly select 30 student IDs from all students
D. select every other student in her classes until she has selected a total of 30 students
Answer:
D
Step-by-step explanation:
because it's normal reasonal if it is wrong i will look for a better answer
Answer:
A. select all students who are currently in the chess club
Step-by-step explanation:
If the teacher randomly selects students, there is a greater chance that many don't play chess. But, if the teacher selects all the students who are currently in the chess club, most likely all of them play chess because they are in the chess club.

If you use a calculator to help you with the computation of the addition or division, you may as well use the calculator's "mean" function to do the job.
The mean of the given 6 values is their sum, divided by 6. The units of the mean are the same as those of the contributors.
(1117 +1409 +675 +536 +1398 +1621)/6 = 6756/6 = 1126 . . . . degrees F

Type a digit that makes this statement true.
7,176,260 is divisible by 3.
Submit
Answer:
1, 4 or 7
Step-by-step explanation:
The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.
adding 1 gets you 30, which we know is divisible by 3.
then, instead of trying every digit, we can note that
30 , 33 , 36 , 39 ....
are divisible by 3.
But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant
so, we want to find out if we can make 29 into 30, 33, or 36
adding 1 to 29 = 30
adding 4 to 29 = 33
adding 7 to 29 = 36
So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)

The scatter plot below represents the weight of a box of cookies based on the number of cookies in the box. A best-fit line shows the relationship.
Answer:
a. true
b. false
c. false
d. false
e. true
Step-by-step explanation:
a is true because the graph is measuring the weight of the box based on the number of cookies in it, and the box has weight even without cookies in it.
b is false because the slope of the line is 1/2, and each cookie weighs 1/4 oz.
c is false because there is an association between the number of cookies and the weight of the box.
d is false because that is the weight of one cookie, and doesn't take into account the weight of the box by itself.
e is true because the graph shows that at 13 cookies, the box weighs around 3.75 ounces.
Rachel enjoys exercising outdoors. Today she walked 5 2/3 miles in 2 2/3 hours. What is Rachel’s unit walking rate in miles per hour and in hours per mile?

To find the volume of a rectangular prism you multiply the 3 dimensions, length x width x height. What combination of numbers will give me a volume of 17?
Answer:
1, 1, 17
Step-by-step explanation:
17 is a prime number. This means the only factors are 1, and 17. This means that since only 17, and 1 multiply to 17, to get a volume of 17 you can only use 1, and 17 (1, 1, and 17)
