Answer:x = 200 students
y = 300 non-students
Step-by-step explanation:
5x + 10y = 4000
x + y = 500
Set y = 500-x
5x + 10(500-x) = 4000
5x + 5000-10x
-5x + 5000 = 4000
-5x = -1000
x = 200 students
y = 300 non-students
Let's double checks
5(200) + 10(300)
1000 + 3000 = 4000

A Broadway musical came to town. The auditorium filled all 1,000 seats at two-level pricing. Level 1 tickets are $75 each, and level 2 tickets are $100 each. The theater made $25,000 from ticket sales. The system of equations that models this scenario is:
x + y = 1,000
75x + 100y = 25,000
What do the x and y represent in the system?
x represents the number of level 1 tickets; y represents the number of level 2 tickets
x represents the number of level 2 tickets; y represents the number of level 1 tickets
x represents the cost of level 1 tickets; y represents the cost of level 2 tickets
x represents the cost of level 2 tickets; y represents the cost of level 1 tickets
Answer:
x represents the number of level 1 tickets; y represents the number of level 2 tickets
Step-by-step explanation:
The first equation (x + y = 1,000 ) shows that x + y equal to the number of seats in the auditorium. That means that they represent the number of tickets. In the second equation (75x + 100y = 25,000) x and y are being multiplied by the cost of their level ticket. So x represents the number of level 1 tickets; y represents the number of level 2 tickets.

You roll a standard dice two times. What is the probability of getting a 6
on the first roll, then an even number on the second roll?
Answer:
4 out of 12 chance.
Step-by-step explanation:
So its a 1 out of 6 chance for the first die, and a 3 out of 6 chance on the second die, so a 4 out of 12 chance of what was said to happen.
First die:
You want to roll a 6. There is one number on each side of the die, and there are 6 sides. Since you can only get a side with 6 once, you have a 1 out of 6 chance of landing a 6.
Second die:
You want to roll an even number. There are 3 even numbers on the die (2, 4, and 6), and there are 6 sides, with the other 3 sides being odd (1, 3, and 5). Since you can only get a side that is even three times, you have a 3 out of 6 chance of landing an even number (2, 4, or 6).
Combine these probabilities together, and you result in a 4 out of 12 chance of getting the requirements. The 4 comes from adding the chance of getting a 1 and 3 even numbers, and the 12 comes from adding the 2 6's (since two dices would result in 12 sides).

Antoine is on vacation with his family. They have a vacation budget of $1,400. Antoine predicts they will spend $110 each night on the hotel, $80 a day on food, and $100 a day on activities. They will also spend $120 on gasoline for the entire trip. Write an inequality to find how many nights, n, they afford to stay on vacation. What is the longest vacation they can take?
Answer:
290n + 120 ≤ 1400
4 days
Step-by-step explanation:
Given that:
Vacation budget = $1400
Cost on hotel = $110 per night
Cost on food = $80 per day
Cost on activities = $100 per day
Cost on gas = $120 for entire trip
Number of nights they can afford to stay
Let the Number of nights they can afford = n
((110 + 80 + 100) * number of nights) + 120 ≤ vacation budget
290n + 120 ≤ 1400
290n ≤ 1400 - 120
290n ≤ 1280
n ≤ 1280 / 290
n ≤ 4.4137
Hence, longest vacation they can take is 4 days

Grayson has 4 small photo albums and 6 large photo albums. Each small album can hold up
to 112 photographs. Each large album can hold up to 184 photographs. How many photos can
Grayson keep in the albums? Enter your answer in the box.
Answer:
1552 Photos
Step-by-step explanation:
I relabeled the albums as SP (Small album) and LA (Large album)
1 la holds 184
1 sp holds 112
112 • 4 = 448
184 • 6 = 1,104
448 + 1,104 = 1552

Lucy's dog lost 6 pounds. How much weight does her dog need to gain in order to have a net change of 0 pounds?
Answer:
Lucy's dog needs to gain 6 pounds.
Step-by-step explanation:
Lucy's dog lost 6 pounds so the dog will have to gain 6 pounds.
The Dog need to gain 6 pounds for net change of zero pounds.
We have Lucy's whose dog lost 6 pounds.
We have to find out how much weight does her dog need to gain in order to have a net change of 0 pounds.
If you have 'x' toffees and you lost 'y' toffees, then how many toffees you have to buy to recover the lost toffees?Number of toffees left after loosing 'y' toffees = x - y
The number of toffees to buy = x - (x - y) = x - x + y = y
A/Q -
Let the Dog's initial weight be - W
After loosing 6 pounds, the weight will be - W - 6
For a net change of zero pounds, he needs to add = W - (W - 6) = W - W + 6 = 6 Pounds.
Hence, he need to gain 6 pounds for net change of zero pounds.

Solve the following absolute value equation in the work space. Be sure to circle
your answer(s).
|3t +3|=18
Answer: so the answer t= 5, -7
3t + 3 = 18
( we subtract 3 from both sides)
3t + 3 = 18
- 3 -3
3t = 15
( then we divide both sides by 3 )
3t/3 = 15/3
t = 5
(and this is the negative part, we do most of the same steps as teh last one)
3t + 3 = -18
- 3 -3
3t = -21
3t/ 3 = -21/ 3
t = -7

4. The perimeter of a rectangle is 56 centimeters. The length of the rectangle is 2 centimeters more than
the width. Find the dimensions of the rectangle. (Hint: P = 21 + 2w)
I
Answer:
The rectangle has a length of 15 cm and a width of 13 cm
Step-by-step explanation:
Let w represent the width of the rectangle, and let w + 2 represent the length of the rectangle.
Use the perimeter formula, P = 2l + 2w, and plug in the perimeter and w + 2:
P = 2l + 2w
56 = 2(w + 2) + 2w
Simplify and solve for w:
56 = 2w + 4 + 2w
56 = 4w + 4
52 = 4w
13 = w
Then, add 2 to this to find the length:
13 + 2
= 15
So, the rectangle has a length of 15 cm and a width of 13 cm.

4 Abi is going to buy ingredients to make 65 hot chocolate drinks.
She needs 12 g of chocolate powder and 5 marshmallows to make each drink
Abi can buy
chocolate powder in 250 g jars at £2.99 per jar
marshmallows in bags of 120 marshmallows at £1.45 per bag
Work out the total cost of the chocolate powder and the marshmallows she needs to buy.
Answer:
To make 65 chocolate drinks, she needs:
12 g of chocolate powder and 5 marshmallows per drink.
Then she needs:
12g*65 = 780 grams of chocolate powder.
We know that the chocolate powder comes in jars of 250g, such that each one costs £2.99
If she buys 3 jars, she will have: 3*250g = 750g
So she will not have enough, then she needs to buy 4 jars.
Then in chocolate powder, she will pay 4 times £2.99 = £11.96
And for marshmallows, she needs:
65*5 = 325 in total.
Marshmallows come in bags of 120, then the number of packs that Abi needs to buy is:
325/120 = 2.7
That should be rounded up (because she can not buy a 0.7 of a bag)
Then she needs 3 bags, and each bag costs £1.45
Then the total cost in marshmallows is 3*£1.45 = £4.35

Mr. Scott likes to pose interesting problems to his Mathematics classes. Today,
he started with the expression 6^2020 + 7^2020. He stated that the expression was
not equivalent to 13^2020 and that he was not interested in the actual sum. His
question to his class and to you is, “What are the final two digits of the sum?
Answer:
The last two digits of 6²⁰²⁰ + 7²⁰²⁰ is 7, 7
Step-by-step explanation:
The given question is to find the value of the sum of two numbers 6²⁰²⁰ + 7²⁰²⁰, where, 6²⁰²⁰ + 7²⁰²⁰ ≠ 13²⁰²⁰
We have;
The last two digits of the powers of 6 are;
6¹ = 6, last two digits = 06
6² = 36, last two digits = 36
6³ = 216, last two digits = 16
6⁴ = 1,296, last two digits = 96
6⁵ = 7,776, last two digits = 76
6⁶ = 46,456, last two digits = 56
6⁷ = 279,936, last two digits = 36
6⁸ = 1,679,616, last two digits = 16
6⁹ = 10,077,696, last two digits = 96
6¹⁰ = 60,466,176, last two digits = 76
6¹¹ = 362,767,056, last two digits = 56
Therefore, the last two digits repeat itself every 5 times
For 6²⁰²⁰, the last two digits will be for the 2020/5 = 404 complete times, which will be 76
The last two digits of the powers of 7 are;
7¹ = 7, last two digits = 07
7² = 49, last two digits = 49
7³ = 343, last two digits = 43
7⁴ = 2,401, last two digits = 01
7⁵ = 16,807, last two digits = 07
7⁶ = 117,649, last two digits = 49
7⁷ = 823,543, last two digits = 43
7⁸ = 5,764,801, last two digits = 01
Therefore, the last two digits repeat itself every 4 times
For 7²⁰²⁰, the last two digits will be for the 2020/4 = 505 complete times, which will be 01
Therefore, the last two digits of 6²⁰²⁰ + 7²⁰²⁰ is 76 + 01 = 77, which is 7, 7
