Volunteers at Sam's school use some of the student council's savings for a special project. They buy 3 backpacks for $7 each and fill each backpack with paper and pens that cost $6. By how much did the student council's savings change because of this project?
The savings was changed by
dollars.
Answer:
Sam's student council spent $39 on backpacks + paper and pens.
Step-by-step explanation:
They bought 3 backpacks for $7 each. 3 x 7 = $21.
They also filled those backpacks with paper and pens costing $6 each. 3 backpacks x $6 = $18.
Now, add the two prices.
18 + 21 = 39
hope this helps :)
Here is trapezoid A in the coordinate plane:
If you drew Trapezoid B, the image of A after a 90\circ∘ rotation clockwise, using the origin as the center of rotation, what would be the coordinates of each of the vertices?
Answer:
(1,-2) (3,-2) (4,-4) (1,-4)
Step-by-step explanation:
First of all I noted that the origin would be the centre of rotation.
Then I chose a point of Trapezoid A: I selected the point closest to the centre of rotation which was (2,1) , since that is the easiest one to do. However, this works for any point
Then I drew a line from the point (2,1) to the centre of rotation (the origin)
From the origin I then drew another line perpendicular (at a right angle to) the line that I previously drew (between the origin and point (2,1)). I drew this line so that it was also the same length as the previously drawn line and I drew it in the direction of rotation which was clockwise i.e., to the right. This line therefore went from the origin to point (1,-2).
I have now deduced that the point (1,-2) is the same as point (2,1) but in the rotated Trapezoid B.
From there I simply just rotated shape A 90 degrees clockwise so that I knew what the shape would look like if it was rotated.
Then I just drew in the other points to make the rest of the shape.
Sorry if this is hard to understand. I would be able to explain better if I was able to draw this out for you
The required coordinate of the image of the rotation of the trapezoid (1, -2) (3, -2) (4, -4) (1, -4)
Given that,
To determine the coordinate of the given trapezoid after the 90° clockwise rotation with origin as the center of rotation.
The graph is a demonstration of curves which gives the relationship between the x and y-axis.
Here,
Intial coordinates of the trapezoid, (1,2) , (3, 2), (4, 4) and (4, 1)
After the rotation of 90° clockwise, the trapezoid is translated to the 4 quadrants and the new coordinates are (1, -2) (3, -2) (4, -4) (1, -4).
Thus, the final coordinates are, (1, -2) (3, -2) (4, -4) (1, -4).

Evaluate. Write your answer as a fraction in simplest form.
2/9 +5/12 -7/18
Answer:
1/4
Step-by-step explanation:
Step 1 : Find a common denominator. We will use 36 as the denominator since 9, 12, and 18 are all factors of 36.
Step 2 : The number you multiple the denominator by must be the same number you multiply its numerator by.
Example : 2/9 To get a denominator of 36 you need to multiply 9 by 4. Now you need to multiply 2 by 4 as well.
Step 3 : Convert fractions into the new fractions
2/9 (times 4 on both sides) = 8/36
5/12 (times 3 on both sides) = 15/36
7/18 (times 2 on both sides) = 14/36
Step 4 : Plug new numbers into the equation.
8/16 + 15/36 - 14/36
Step 5 : Solve
8/16 + 15/36 = 23/36
23/36 - 14/36 = 9/36
Step 6 : Simplify
9/36 (divide by 9 on both sides) = 1/4

Step-by-step explanation:
When this 3-digit number is rounded to the nearest hundred it rounds down to 600. The digit in the ones place is the third odd number that you count beginning with 1. The sum of the digits is 13. What is the number?
Answer:
1. rounds down to 600 = 601 - 649
2. The digit in the ones place is the third odd number that you count beginning with 1. = 605
3. The sum of the digits is 13
Answer:
625
Step-by-step explanation:
Firstly, I found the ones place because I just needed to know the third odd number starting from 1. The first odd number is 1 then 3 and then 5, so I know that the digit in the ones place is 5.
Ones place: 3rd odd number: 1, 3, 5
Then, I looked at the hundreds place, because I know that it is rounded to down to 600 in the nearest hundred, I know it has to be 649 or smaller and bigger than 600. In the range of 600-649, the hundreds place remains the same, and therefore I know that the digit in the hundreds place is 6
Finally, to determine the tens place, I can do 13-(6+5) I can do this because I know that the sum of the digits is 13. Because 13-11=2, I know that the digit in the tens place is 2
Final number: 625

The equation 4.05p+14.40=4.50(p+3) represents the number p of pounds of peanuts you need to make trail mix. How many pounds of peanuts do you need for the trail mix?
Answer: p=2
Step-by-step explanation:
4.05p+14.40=4.50p+13.50
4.50p-4.50p=13.50-14.40
-0.45p=-0.90
p=-90/-0.45
p=2

3/4x + 3 -2x = -1/4 + 1/2x + 5
Combine like terms:
-1 1/4x + 3 = 1/2x + 4 3/4
Subtract 3 from both sides:
-1 1/4x = 1/2x + 1 3/4
Subtract 1/x from both sides
-1 3/4x = 1 3/4
Divide both sides by-1 3/4
X = -1
Which number has a 9 that is 1/10 the value of the 9 in 296?
195
409
981
1,956
Answer:
409
Step-by-step explanation:
This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.
1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)
The only number which has 9 as its final digit is 409

Find: 11/3 ÷ 2/3
The quotient is 5 and ?
Answer:
11/3 ÷ 2/3 = 5 1/2
Step-by-step explanation:
When doing divison of fractions, you do these steps
11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.
11/3 × 3/2. Now all you have to do is multiply
11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2

Identify the graph of the following equation.
x < -3
Answer:
The 1st Graph (A)
Step-by-step explanation:
Test by substituting values for "x":
By substituting the numbers of 0 (0 < -3), -1 (-1 < -3), and -2 (-2 < -3), does that make the statement true?
The answer is FALSE. None of those values are satisfactory.
---
Therefore, by substituting -4 (-4 < -3), -5 (-5 < -3), and -6 (-6 < -3), these values are satisfactory and makes the statement true.
does anyone know how i can find the value of the expression ? it's a pretest so i dont know anything on here .
