Mira picked two numbers from a bowl. The difference of the two numbers was 4, and the sum of one-half of each number was 18. The system that represents Mira’s numbers is below.x – y = 4

x + y = 18

Which two numbers did Mira pick?

(10, 8)

(18, 4)
(20, 16)
(40, 32)

Answers

Answer 1

Answer: Based on the description, the system can be explained in equation form as x - y =4, an (x + y)/2 = 18. Based on these equations, we can plus in numbers from the given answers and come up with a solution where both equations are satisfied. The two numbers that satisfy both equations are (20, 16).

Answer 2

Answer:

Let

x------> the first number

y-----> the second number

Assume $x> y$

we know that

$x-y=4$ ----> equation A

$(x)/(2)+ (y)/(2)=18$

Multiply by $2$ both sides

$x+y=36$ -----> equation B

Adds equation A and equation B

$x-y=4 \nx+y=36\n------- \n x+x=4+36\n 2x=40\n x=20$

Find the value of y

$20-y=4$

$y=20-4=16$

therefore

the answer is the option

$(20,16)$

I have a 96 in class and i get a 75 on a assignment that’s worth 10% whats my grade?

Answers

Answer:

Step-by-step explanation:

That would either be a B or a C!

Answer:

To calculate your overall grade, we can use the weighting of each component. Since the assignment is worth 10% of your grade, we can calculate its contribution using the following formula:

(96 * 90%) + (75 * 10%)

First, we multiply your current grade of 96 by 90% (which represents the remaining 90% of your grade) to calculate its contribution. Then, we multiply your assignment grade of 75 by 10% to calculate its contribution. Finally, we add these two contributions together:

(96 * 90%) + (75 * 10%) = 86.4 + 7.5 = 93.9

Therefore, your grade after receiving a 75 on an assignment worth 10% would be approximately 93.9%.

If m > n, which inequalities must be true? Check all that apply. m + 2.1 > n + 2.1 m - (-4) > n -(-4) m + 3 > n-3 16.5 + m > 16.5 + n 1 m > n + 2 9 + m > 6 + 1

Answers

Let's begin by listing out the information given to us:

m > n

We will proceed to solve the inequalities given as shown below:

$\begin{gathered} If\colon m>n \n \n m+2.1>n+2.1 \n \text{Subtract ''2.1'' from both sides, we have:} \n m>n \n m+2.1>n+2.1\Rightarrow m>n \n \therefore m+2.1>n+2.1(TRUE) \n \n m-(-4)>n-\mleft(-4\mright) \n \Rightarrow m+4>n+4 \n \text{Subtract ''4'' from both sides, we have:} \n m>n \n m+4>n+4\Rightarrow m>n \n \therefore m+4>n+4(TRUE) \n \n m+3>n-3 \n \text{Subtract '3'' from both sides, we have:} \n m>n-3-3\Rightarrow m>n-6 \n m>n-6\ne m>n \n \therefore m+3>n-3(FALSE) \n \n \end{gathered}$

The last three choices are below:

$\begin{gathered} 16.5+m>16.5+n \n \text{Subtract ''16.5'' from both sides, we have:} \n m>n \n 16.5+m>16.5+n\Rightarrow m>n \n \therefore16.5+m>16.5+n(TRUE) \n \n m>n+2 \n m>n+2\ne m>n \n \therefore m>n+2(FALSE) \n \n \n \end{gathered}$

The inequalities marked as TRUE are the inequalities that apply

Write an expression that represents the height of a tree that begins at 2 feet and increases by 4 feet per year. Let y represent the number of years. PLEASE HELP ME

Answers

Answer:
2+4y

Explanation:
The height of the tree increases by 4 feet per year, so we know to multiply 4 by the number of years to find its height. The initial height of the tree is 2, so we add 2 to 4y.

Example: The height of the tree in 6 years
2+4y
2+4*6
=2+24
=26

I hope this helps!

2+4y
