Part A: The system of equations  is

6x + 4y= 212

3x + 5y= 202

Part B: The solution of the system of equation is x= 14 and y= 32

Parte C: The solution means that the price of t-shirts and the price of swatshirts are $14 and $32 respectively.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

A solution to a system of two or more linear equations is a solution that simultaneously satisfies all the equations in the system.

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is

6x + 4y= 212

3x + 5y= 202

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "y" from the first equation:

4y= 212 - 6x

y= (212 - 6x)÷ 4

y= 212÷4 - 6÷4x

y= 53 - 3/2x

Substituting this expression in the second equation:

3x + 5×(53 - 3/2x)= 202

Solving:

3x + 5×53 - 5×3/2x= 202

3x + 265- 15/2x= 202

3x - 15/2x= 202 - 265

-9/2x=-63

x= (-63)÷ (-9/2)

x= 14

Remembering that y= 53 - 3/2x, you get:

y= 53 - 3/2×14

y= 32

The solution of the system of equation is x= 14 and y= 32. This means that the price of t-shirts is $14 and the price of swatshirts is $ 32.

Answer:

x = -3.57

Step-by-step explanation:

First, subtract the answer and the other interger: -5.37 - (-1.8). Two negatives equal a negative. So, your answer would be -3.57

To double check, you would add -3.57 + (-1.8) [-+-=-] Equals, -5.37.

The probability that he at least misses one is equal to 61/125.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given in the question

basketball player makes 80% of his free throw attempts i.e.

P(Success) = 4/5 or 0.8

P(Miss the attempt) = 1 - 0.8 = 0.2 or 1/5

Number of sample (n) = 3

We need to calculate probability that he at least misses one i.e.

P(X > = 1) = 1 - P(X < 1) = 1 - P(X = 0)

Here we will use binomial probability distribution which can be calculated as

P(X = n |N, p)= NCn x (p^n) x (1-p)^(N-n)

P(X > = 1) = 1 - P(X < 1) = 1 - P(X = 0) = 1 - 3C0 x (1/5)^0 x (1 - 1/5)^(3-0)

=  1 - (1 x 1 x 64/125) = 1 - 64/125 = 61/125

Hence, the probability that he at least misses one is equal to 61/125.

The linear equations for cost price and selling price are c = 3x + 35 and  y = 5x.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Let Max make x cups of lemonade cup.

According to given conditions,

Cost of 1 cup of lemonade = $3.

Also, Max pay for renters fee = $35.

The cost of x cups of lemonade = 3x

The total cost c = 3x + 35

Since, Max sells lemonade for $5 per cup.

Let the selling price is represented by y,

Then selling price y = 5x

how many leaves does the tree have = ?

The degree of the non leaf vertices are 10, 7, 4, 4

let the number of leaves be = k

So the tree has 4+k vertices.

and hence (4+k)-1 edge ⇒ 3+k

so ∑ deg(v) = 10+7+4+4+1k

                   = 25+k

and 2[E(T)] = ∑ deg(v)

2(3+k) = 25+k
