Answer:
2(n+7)=3n
Step-by-step explanation:
"A number" is unknown so just create a variable in this case I made it "n."
We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.
GUYS, PLEASE ANSWER MY QUESTION! Please it's due today, everybody else got their questions answered! Listen to me!
Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?
Answer:
Arianna is correct
Step-by-step explanation:
She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10
Answer:
5x - 3x = 10
2(2x - 1) = 46
6x - 15 = 75
x+(x - 10) = 26
Step-by-step explanation:
5x - 3x = 10
2x = 10 Divide by 2
x=5
2(2x - 1) = 46 Distribute the 2
4x - 2 = 46 Add 2
4x = 48 Subtract by 4
x = 12
6x - 15 = 75 Add 15
6x = 90 Divide by 6
x=15
x + x - 10 =26 Add the x's together and the 10
2x = 36 Divide by 2
x = 18

The quotient of a number decreased by 7 and -2 is -10.
Step-by-step explanation:
First, a quotient is the answer to a division equation.
So its like y÷z=x
X is our quotient.
Since x is -10 when decreased by 7 and -2, we can write:
x-7-(-2)=-10
x-7+2=10
x-5=10
x=15
We now know that x is 15.
Using that, we can write out our equation.
Since you say do not solve, i have purposefully NOT solved this.
You should use y as a dividend and z as a divisor!
Good luck.

Mimi bought some fabric for a sewing project. The fabric cost $15.40 per meter. She bought 250 centimeters of fabric.
How much did Mimi pay for the fabric?
Answer:
$38.50
Step-by-step explanation:
so there are a hundred centimetres in a meter so u have to divide the 250 by 100
250 / 100 = 2.5 meters
and its 15.40 for 1 meter and she bought 2.5 so multiply those
15.40 * 2.5 = 38.50
she paid $38.50 for 2.5 meters of fabric
Answer:
$38.50
Step-by-step explanation:
There are 100 centimetres in a meter. If Mimi bought 250 centimetres of fabric, that is 2.5 meter. So then we do 2.5 x 15.40 = 38.50. Make sure you add the $ sign!

Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2

Ms.Alvarez's math class surveyed 10 students in 6th grade and 10 students in 7th grade. The class asked how many hours of chores each student did the previous weekend. The results were displayed in two histograms.
Mean is greater for grade 7.
Median is greater for grade 7.
So, the correct options are B and D.
What is mean and median?"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.
The median is the middle number in a set of values when those values are arranged from smallest to largest."
Mean for grade 6 is
= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]
= [tex]\frac{10}{7}[/tex]
Mean for grade 7 is
= [tex]\frac{1+2+5+2}{4}[/tex]
= [tex]\frac{10}{4}[/tex]
From both we get, Mean is greater for grade 7
Median for grade 6 is 1
Median for grade 7 is
= [tex]\frac{2+5}{2}[/tex]
= 3.5
From both we get, Median is greater for grade 7
So, the correct options are B and D.

Answer:
So for box 5 you would say that the weight of the box (48) plus the movers weight (185) is less than or equal to the amount of weight the elevator can hold which represents the 2,000. The last box could be something like "Amanda is shipping a 48lb T.V. the sound bar it came with and speakers totals to 180lbs. Amanda can't ship these items if they exceed 2,000 pounds total. Create an inequality to show if Amanda will be able to ship all these items without going over the allowed weight.
