At a bake sale, a student spent $5.70 buying 3 brownies and 5 cookies. His
friend spent $4.50 buying 1 brownie and 6 cookies. What is the price of a
brownie?
Answer:
i think the answer would be 90 cents for each brownie
Step-by-step explanation:
This can be solved as a system of 2 linear equations.
x = price of a brownie
y = price of a cookie
Since $5.70 bought 3 brownies and 5 cookies, our first equation is:
3x + 5y = 5.70
Since $4.50 bought 1 brownie and 6 cookies, our second equation is:
x + 6y = 4.50
So just solve the following system for x and y:
3x + 5y = 5.7
x + 6y = 4.5
Get x = 4.5 - 6y from the bottom equation and substitute for x in the top equation:
3(4.5 - 6y) + 5y = 5.7
Solve for y:
13.5 - 18y + 5y = 5.7
-13y = -7.8
y = 7.8/13 = 0.6 = price of cookie = $0.60
Now substitute this value of y into either equation and get x. From the bottom equation,
x + 6(0.60) = 4.50
Solve for x:
x = 0.9 = price of brownie = $0.90

The linear function y = 15x represents the distance y (in miles) you have traveled after x hours
during a 4-hour bicycle ride.
Which graph represents the situation?
Answer:
The graph to in the top right
Graph B, represents the situation.
What is a linear function?A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by;
y = f(x) = p x + q
Given linear function:
y = 15x
where y is distance in miles
x is time in hours.
Graph A only represents the points and not the linear function.Graph B represents the linear function.putting the value (4,60) in given linear function,
y = 15x
⇒ 60 = 15 × 4
⇒ 60 = 60
Graph C and Graph D has no scale for x variable; the time in hours, hence do not represent the situation.Hence, by the above observation, Graph B represents the linear function, y = 15x.

A store is advertising a sale with 10% off all items in the store. Sales tax is 5%.A 32-inch television is regularly priced at $295.00. What is the total price of the television, including sales tax, if it was purchased on sale? Fill in the blank to complete the sentence. Round your answer to the nearest cent.
Answer:
$280.25Step-by-step explanation:
Step one;
given
price= $295.
Discount
10% of 295
=10/100*295
=0.1*295
=29.5
new price= 295-29.5=
=$265.5
Tax
5% of 295
=5/100*295
=0.05*295
=14.75
tax=$14.75
Total price= discount sales+tax
=265.5+14.75
=$280.25

How would you express the area of the rectangle using the Distributive Property?
A rectangle with length x plus 5 and width 3.
A. 5(x + 3)
B. x(3 + 5)
C. 3(x + 5)
D. 3x + 5
Answer:
The area of the rectangle can be found using two different expressions: a(b + c) or ab + ac. The equality of these expressions, a(b + c) = ab + ac, is the distributive property.
The expression that shows the length and width of the rectangle in distributive format is 3(x + 5) = 3x + 15 and this can be determined by using the distributive property.
Given :
A rectangle with length x plus 5 and width 3.
The distributive property is given by:
a(b + c) = ab + ac
The above expression is known as the distributive property. Where a, b, and c represents the three different variables.
So, according to the given data, the length of the rectangle is (x + 5) and the width of the rectangle is 3.
The expression shows the length and width of the rectangle in distributive format.
3(x + 5) = 3x + 15
The above expression also represents the area of the rectangle.
Therefore, the correct option is C).

Welcome to another new game show, “Spinning for Luck!” As a contestant, you will be spinning two wheels. Each wheel is divided into equal sectors. The first wheel determines a possible dollar amount that you could win. The second wheel is the “multiplier”. You will multiply the results of your spins to determine the amount you will win. Unfortunately, you could owe money if your multiplier lands on –2!
a. What is the probability of winning $100 or more?
b. What is the probability of owing $100 or more?
Answer a ) 25%
Answer b ) 8.33%
The following formula can be used to determine the likelihood of both winning and owing $100 or more:
a. ) Chance of winning at least $100:
On the first wheel, there is a 2/6 = 1/3 chance of landing in a sector that equates to $100 or more.
On the second wheel, there is a 3/4 chance of landing on a multiplier other than -2.
The odds of both happening are (1/3) * (3/4) = 1/4 or 0.25.
The likelihood of earning $100 or more is thus 0.25, or 25%.
b. ) Likelihood of having at least $100 in debt:
The odds of landing on a sector with a value on the first wheel that is less than or equal to -$50 are 2/6 = 1/3.
A landing on a -2 multiplier on the second wheel has a 1/4 chance of happening.
1/12, or 0.08333, is the likelihood that both occurrences will occur (1/3) * (1/4).
Thus, the likelihood of owing $100 or more is 0.08333, or around 8.33%.
Therefore the final answer is 25% and 8.33%.
