Breanna and Courtney kept track of the total distance they rode their blcycles over the summer. With one week remaining in the summer, Breanna had ridden her blcycle b miles, and Courtney had ridden her bicycle c miles. During the last week of summer Breanna rode her bicycle 200 miles and Courtney rode her bicycle 500 miles. . For the entire summer, Courtney recorded 180 mlles more than Breanna recorded. Enter an equation that can be used to show that Courtney rode her bicycle 180 mlles more than Breanna rode her bicycle
The equation that shows Courtney rode 180 mlles more than Breanna rode is c = b + 180

b) 2x − 4 = 10
c) 2x + 2y = 48
d) 5x + 2y = 90. no links please!
Answer:
Step-by-step explanation:
4x − 1 = 19
solving for x, x = 5
2x − 4 = 10
x=7
2x + 2y = 48

Sophia buys a supply of toilet paper from costco that comes in a pack 36. She immediately gives 4 rolls of toilet paper to her sister (who shared with her last month). She uses 2 rolls of toilet paper a per month.
(a) Write an expression that represents the situation
(b) Determine how many rolls of toilet paper she will have left after 1 year
EXPLAIN AND SHOW YOUR WORK
I believe she will have 8 rolls of toilet paper left after one year.
She started with 36, then gave away 4, so then she would have 32 left for herself, then she used 2 every month so if you deduct 2 rolls every month for 12 months she would use 24 in one year. So 32-24 is 8.

The number of blueberry muffins Gary bakes each day is 30% of the total number of muffins he bakes. If he baked 24 blueberry muffins on Sunday, what is the total number of muffins baked?
Answer: The answer is 80
Step-by-step explanation:
Answer:
Gary baked 80 muffins on Sunday
Step-by-step explanation:
I can set up a proportion, knowing that 24/x = 3/10, where x is the total number of muffins baked on Sunday. By cross multiplying, I get 240 = 3x. By dividing both sides by 3, I find x = 80.

The price of a bus ticket to Saskatoon is $180. This bus has 56 seats. The bus company is considering dropping this bus fare as part of a promotion to increase the ridership on that route.
The buses has only been at half capacity lately. The companies research shows that for every 5$ decreases they will gain 2 more riders.
1. Define variable and set up an equation to represent his scenario
2. What is the maximum revenue the bus company can earn and what will be the cost of a ticket when the revenue is at a maximum
The bus tickets and price are illustrations of a quadratic function, and the maximum revenue the bus company can earn is $5107.6
The variables of the scenarioThe variable representation used in this scenario are:
Let x represents the number of seatsLet y represents the total amountThe maximum revenueThe price is given as:
Price = $156
The number of seats is given as:
Seats = 56
When the bus is at half capacity, we have:
Seats = 28
As the price decreases by $5, the rider gains 2 more.
So, the revenue equation is:
y = (156 - 5x)(28 + 2x)
Expand
y = 4368 - 140x + 312x - 10x²
Differentiate
y' = 0 - 140 + 312 - 20x
Evaluate the sum
y' = 172 - 20x
Equate to 0
172 - 20x =0
Add 20x to both sides
20x = 172
Divide both sides by 20
x = 8.6
Substitute x = 8.6 in y = (156 - 5x)(28 + 2x)
y = (156 - 5 * 8.6)(28 + 2 * 8.6)
Evaluate
y = 5107.6
Hence, the maximum revenue the bus company can earn is $5107.6

Write the equation of the circle below to complete the square. Also determine the area of the circle.
Answer: [tex](x-7)^2+(y+2)^2=11^2[/tex] ; [tex]A=121\pi[/tex]
Step-by-step explanation:
I have never done a problem like this, so this is my first time attempting it.
The standard form for the equation of a circle is:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
Begin by grouping the 'x' terms and 'y' terms:
[tex](x^2-14x)+(y^2+4y-68)=0[/tex]
Complete the square for the second polynomial:
[tex](\frac{b}{2} )^2=(\frac{4}{2} )^2=4[/tex]
[tex](x^2-14x)+(y^2+4y+4-4-68)=0[/tex]
[tex](x^2-14x)+(y^2+4y+4)-4-68=0[/tex]
[tex](x^2-14x)+(y^2+4y+4)-72=0[/tex]
[tex](x^2-14x)+(y+2)^2-72=0[/tex]
Do the exact same process with the other polynomial:
[tex](x^2-14x-72)+(y+2)^2=0[/tex]
Complete the square:
[tex](\frac{14}{2} )^2=49[/tex]
[tex](x^2-14x+49-49-72)+(y+2)^2=0[/tex]
[tex](x^2-14x+49)-49-72+(y+2)^2=0[/tex]
[tex](x^2-14x+49)-121+(y+2)^2=0[/tex]
[tex](x-7)^2-121+(y+2)^2=0[/tex]
Bring the 121 to the other side to get:
[tex](x-7)^2+(y+2)^2=121[/tex]
[tex](x-7)^2+(y+2)^2=11^2[/tex]
The above expression is the equation of our circle in standard form. It is centered at the coordinates (7, -2) and has a radius of 11 units. The area of a circle if given by:
