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? Explain your thinking.
Answer:
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.

Answer:
l
Step-by-step explanation:
Let x equal the repeating decimal you are trying to convert to a fraction.
Examine the repeating decimal to find the repeating digit(s).
Place the repeating digit(s) to the left of the decimal point.
Place the repeating digit(s) to the right of the decimal point.
Jay simplified the expression 3×(3+12÷3)−4.
For his first step, he added 3+12 to get 15.
What was Jay’s error? Find the correct answer.
Answer:
8
Step-by-step explanation:
Answer:
he should have first preformed oprations in the pratheses so he should have done (3+12/3) first to get 3*(3+4)-4 then do (3+4) and have 3*7-4 next he should do 3*7 and get 21-4 do that and get the answer 17

Regina travels ½ of a kilometer for every ¼ of a minute she drives. You were told that the trip from Times Square to Pelham Parkway is 72 kilometers. How many minutes would her trip have taken by car?
Answer:
36 minutes.
Step-by-step explanation:
The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.
1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.
1/2 x 4 = 2.
72 / 2 = 36.
Her trip would have taken 36 minutes by car.
Answer:
36 minutes.
Step-by-step explanation:
For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)
A school administrator bought 6 desk sets. Each set consists of one table and one chair. He paid $48.50 for each chair. If he paid a total of $663 for the 6 sets, the cost of each table is
a.$ 54.5
b.$62.00
c.$ 110.50
d.$ 159.00
Answer:
b. $62
Step-by-step explanation:
48.50 * 6 = 291
663 - 291 = 372
372 / 6 = $62
The measures of the angles of △ABC are given by the expressions in the table.
Angle Measure
A (6x−1)°
B 20°
C (x + 14)°
What are the measures of angles A and C?
Answer:
First You add all given angles up to equal 180 to give you x then you plug x into equations
Step-by-step explanation:
A= 125 degrees
C= 35 degrees
Answer:
Angle A = 125°
Angle C = 35°
Step-by-step explanation:
This is the equation you would have to solve:
Angle A + Angle B + Angle C = 180°
Fill in the values given:
(6x-1)° + 20° + (x+14)° = 180°
The parentheses don't really matter here. Go on to combine like terms. This gives you:
7x + 33 = 180°
Solve for x. Subtract 33 on both sides. This gives 7x = 147. Divide both sides by 7. This gives x = 21.
Now, go back and fill in 21 for x in the expressions for angles A & C.
Angle A:
6(21) - 1 = 125°
Angle C:
21 + 14 = 35°
You can check your answers using the first equation I mentioned:
Angle A + Angle B + Angle C = 180°
125° + 20° + 35° = 180°
This is a true equation. Therefore, the final answers are:
Angle A = 125°
Angle B = 20°
Angle C = 35°
2) Write the equation for the model below, then solve for x.

multiply both sides by -4 to isolate b
you get b=12
2. combine like terms 3c-4=-8+2c
add 4 to both sides: 3c = -4+2c
subtract 2c from both sides
c=-4

Solve for y.
6y-1.5x=8
Answer: Y = 0.25x + 4/3
Step-by-step explanation:
Step 1: Add 1.5 to both sides
-1.5x + 6 + 1.5x = 8 + 1.5x
6y = 1.5x + 8
Step 2: Divide both sides by 6
6y/6 = 1.5x + 8/6
Y = 0.25x + 4/3

Juli says she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6:10.
Which statement explains whether Juli is correct?
a. She is correct because she can multiply 6 and 10 by any number to form an equivalent ratio.
b. She is correct because 6:10 can be written as 1:2 and there are an infinite number of ratios for 1:2.
c. She is not correct because the multiplication table does not include multiples of 10.
d. She is not correct because 6:10 is equivalent to 3:5 and there are only 9 ratios in the multiplication table that are equivalent to 3:5.
