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.
Step-by-step explanation:
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

Carla is going on a boat tour. The boat will travel a total distance of 70 kilometres during the 10-hour tour. If the boat travels at a constant speed during the tour, what distance in kilometres should the boat travel in 3 hours.
Answer:
21 km I think
Step-by-step explanation:
If you do 70/10 then you get 7 km per hour. Then you do 7*3 and get 21 km in 3 hours

Pls help me I would dearly appreciate it!
Answer:
1. c
2. c
Step-by-step explanation:
1. subract 8 from both sides to get b/-4=-3
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

Answer:
There will be an estimated amount of 1125 faulty souvenir tokens.
Step-by-step explanation:
Hi!
So, let's do this problem out.
So we for every 400 tokens, 3 are faulty
Let's write that in a ratio
3:400
Ok, great!
So, now we know that:
3:400 = x:150,000
We can set up a percent proportion
[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]
To find x, we do:
[tex]x=\frac{3*150,000}{400}[/tex]
[tex]x=\frac{450,000}{400}[/tex]
[tex]x=\frac{4,500}{4}[/tex]
[tex]x=1125[/tex]
There will be an estimated amount of 1125 faulty souvenir tokens.

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 :)

Answer:
A. 23
Step-by-step explanation:
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°

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
