Brianna went into a bakery and bought 2 cookies and 3 brownies, costing a total of $9.50. Nevaeh went into the same bakery and bought 10 cookies and 6 brownies, costing a total of $20.50. Write a system of equations that could be used to determine the price of each cookie and the price of each brownie. Define the variables that you use to write the system.

Answer:

[tex]\frac{1}{32}[/tex]

Step-by-step explanation:

According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.

Total outcome = 2

pr(male) = [tex]\frac{1}{2}[/tex]

pr(female) = [tex]\frac{1}{2}[/tex]

Therefore the probability of male equals the probability of females i.e [tex]\frac{1}{2}[/tex].

Therefore,

pr(a litter of 5 puppies will be males) = [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]

                                                           = [tex]\frac{1}{32}[/tex]

According to Reese's model, the probability that a litter of 5 puppies will be males is [tex]\frac{1}{32}[/tex].

Answer:

[tex]c = 63\\b=21[/tex]

Step-by-step explanation:

Let number of pounds of cans collected by Amy = [tex]a[/tex]

Let number of pounds of cans collected by Bruce = [tex]b[/tex]

Let number of pounds of cans collected by Carlos = [tex]c[/tex]

As per question statement, total number of cans collected = 168

[tex]a+b+c=168[/tex] ..... (1)

Number of pounds collected by Bruce is [tex]\frac{1}{3}[/tex]rd of the pounds of cans collected by Carlos.

[tex]b = \dfrac{1}{3}c ..... (2)[/tex]

Number of pounds collected by Amy is equal to number of pounds collected by Bruce and Carlos combined.

[tex]a = b+c[/tex]

Using equation (2):

[tex]a = \dfrac{1}{3}c +c \\\Rightarrow a =\dfrac{4}{3}c ..... (3)[/tex]

Using equations (2) and (3) in equation (1), we get:

[tex]\dfrac{4}{3}c+\dfrac{1}{3}c+c =168\\\Rightarrow \dfrac{8}{3}c = 168\\\Rightarrow c =63[/tex]

Using equation (2):

[tex]b = \dfrac{63}{3} = 21[/tex]

Answer:

X= 12 (see explanation)

Step-by-step explanation:

I'm doing my best to interpret this without an image. So angle S= 43 degrees, T is 7x-6 and R is 4x+11.

If the sum of the arc RTS= 360 degrees, then do

360= 43+ (7x-6) + (4x+11)

X= 312/11  <- this looks iffy

If the sum of the arc RTS= 180 degrees, then do

180= 43+ (7x-6) + (4x+11)

X= 12  <- this looks like a normal solution

Step-by-step explanation:

I checked on the usa test prep and its what those three

The options satisfying expressions that result to zero are,

A. - 52 + 52.

E. - 83 - ( - 83).

A number's additive inverse is a number that is added to it until the result is zero.

A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.

A number added to it's additive inverse results to zero.

From the given options the only options that satisfies the result to be zero

are,

- 52 + 52.

- 83 - (- 83).

= - 83 + 83.

As the negative signs distribute to make it a positive number.

Answer:

Always

Step-by-step explanation:

An equiangular triangle is a triangle with three congruent interior angles. The angles of any triangle add up to 180 degrees. With three angles in a triangle that are all equal, this means each angle is 60 degrees (because 180 divided by 3 is 60).

An Acute triangle is a triangle with all of its angles being something less than 90 degrees. Since an equiangular triangle's angles all measure as 60 degrees, then the statement in the question is always true.

Answer:

f^-1(4) = 2

f^-1(-5) = -4

f^-1(0) = 0

Step-by-step explanation:

To find the inverse of the function, we simply switch the places of x and y

You simply find the value given on the y-axis and trace to the x-axis

Thus, we have the following ;

f^-1(4) = 2

f^-1(-5) = -4

Answer: HL

Step-by-step explanation: Because I passed this on Acellus

Triangle ABD and ACD are congruent based on HL congruence theorem

Two figures are said to be congruent of they have the same shape and all the corresponding sides and angles are congruent.

The HL (hypotenuse leg) congruence theorem states that if the hypotenuse and one leg of a triangle is congruent to another triangle, then both triangles are congruent.

In triangle ABD and ACD;

BD = CD and AD ≅ AD

Hence Triangle ABD and ACD are congruent based on HL congruence theorem

Answer:

-2

Step-by-step explanation:

first, you want to graph your points on a graph. A really good online graphing calculator i like is called desmos.

next, slope is rise over run. count how many units up or down from leftmost point to the other. in this case it is -8.

third, find the run part of the slope by counting units right or left from the leftmost point to the other. in this case it is 4.

last, but the two numbers together in a fraction and simplify. rise over run.

-8/4 which simplifies to -2/1 which is the same thing as -2
