Given; Ahmed bought a DVD for $15. He sold it to Barbara, making a 20% loss.
We need to find that how much did Barbara pay for it.
Barbara later sold the DVD. she made 20% profit and how much did She pay for it.
a) Now, multiply by 80% because he lost 20%.
15 x 80%
15 x 0.8 = 12$ dollars
b) Now, multiply by 120% because she made 20% more than 100%- regular price.
12 x 120%
12 x 0.12 = 14.40$

Answers
Answer/Step-by-step explanation:
First, find the constant of proportionality, k, between miles driven y and gallons of gas available in his car, x.
If he drives 200 miles using 5 gallons of gas, therefore, constant of proportionality = y/x = 200/5 = 40
The equation describing this relationship, is [tex] y = kx [/tex], where k is the constant of proportionality.
Plug in the value of k. The equation would be:
[tex] y = 40x [/tex]
Use this to create the table needed by substituting x (gallons of gas) into the equation:
Gallons of gas (x) ==> Miles (y)
0 ==> [tex] y = 40x = 40(0) = 0 [/tex]
1 ==> [tex] y = 40x = 40(1) = 40 [/tex]
2 ==> [tex] y = 40x = 40(2) = 80 [/tex]
3 ==> [tex] y = 40x = 40(3) = 120 [/tex]
4 ==> [tex] y = 40x = 40(4) = 160 [/tex]
5 ==> [tex] y = 40x = 40(5) = 200 [/tex]

Answer: The answer is 12.
Step-by-step explanation:
Answer:
The answer is 12
Step-by-step explanation:
This because on the x side the second value is 16 and 2×8=16. You notice the x side are multiples of 8. So the other side will be mutiples of 6. You can see that because 6 is your starting number and it has to be proportional. 6×2=12. Good Luck!!
The perimeter of a standard basketball court is 288 feet. The length is 44 feet longer than the width. What are the dimensions of the court?
Answers
Answer:
Perimeter = 2l + 2w //l=length, w=width
l = 44 + w
Now substitute 44 + w in place of l in the above equation and you have
2(44 + w) + 2w = 288
=> 88 + 2w + 2w = 288
=> 88 + 4w = 288
=> 4w = 200
=> w = 50 and l = 44 + 50 = 94
2*94 + 2*50=288
Step-by-step explanation:

The angles of a quadrilateral are in the ratio 1:3:7:9. Find the measure of each angle
Answers
According to the question,,,,angles are in the ratio of 1:3:7:9
If one angle is x other would be 3x next would be 7x and last angle would be 9x(ratio=1:3:7:9)
Add em’ up,,,,and we know sum of the angles in a quadrilateral is equal to 360.
So,
X+3x+7x+9x=360
Solve it,and we’ll get x=18
Now if x=18 other angle will be 3(18)=54, 7(18)=126 and last angle 9(18)=162

A pizza was divide
into 12 slices. Kesh
ate 2 slices. Jorge
ate 3 slices. What
fraction of the pizza
was left over?
Answers
Total number of slices = 12
No. of slices eaten by Kesh = 2
No. of slices eaten by Jorge = 3
No. of slices left
= Total number of slices - (No. of slices eaten by Kesh + No. of slices eaten by Jorge)
= 12 - (2 + 3)
= 12 - 5
= 7
Fraction of the pizza left
= No. of slices left/Total number of slices
= 7/12
Answer: 7/12
Find the total amount of pizza eaten.
Kesh = 2 slices
Jorge = 3 slices
Total eaten: 5/12
Subtract 5/12 from 12/12.
12/12 - 5/12 = 7/12
Answer = 7/12

Solve the literal equation for y. 20=8x+4y
Answers
Answer:
y=2x+5
Step-by-step explanation:
−8x+4y=20
Step 1: Add 8x to both sides.
−8x+4y+8x=20+8x
4y=8x+20
Step 2: Divide both sides by 4.
4y4=8x+204
y=2x+5
Answer:
y=2x+5
Step-by-step explanation:
Let's solve for y.
20=8x+4y
Step 1: Flip the equation.
8x+4y=20
Step 2: Add -8x to both sides.
8x+4y+−8x=20+−8x
4y=−8x+20
Step 3: Divide both sides by 4.

If each bag of tokens weighs 5 3/4 pounds, how many pounds do 3 bags weigh?

Step-by-step explanation:

The weight of 3 bags will be 17 ( ¹ / ₄ ) pounds.
What is multiplication?Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.
Given that If each bag of tokens weighs 5 (³/₄) pounds and there are three bags.
To calculate the weight of all the bags multiply the weight of each bag by the number of the bags.
Total weight = 5 (³/₄) x 3
Total weight = 5 (³/₄) x 3
Total weight = ( 23 / 4 ) x 3
Total weight = 69 / 4 = 17( ¹ / ₄)
Therefore, the weight of 3 bags will be 17 ( ¹ / ₄ ) pounds.
