The correct ordered pair is (3, 0).

You can find this by trying them in the equations and looking for true statements.

y > -2x + 3
0 > -2(3) + 3
0 > -6 + 3
0 > -3 (TRUE)

y < x - 2
0 < 3 - 2
0 < 1 (TRUE)

Since both of those are true, the pair works.

Answer:

It would make it 3x

Step-by-step explanation:

4x is just a simplified version of 4 multiplied by x

4*x-x wouldn't equal 4 because you aren't following

On Thursday a local shop sold a combination of 417 hamburgers and cheese burgers. The number of cheeseburgers sold was two times

seropon [69]

Answer:

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.

Step-by-step explanation:

Let

x -----> the numbers of hamburgers sold on Thursday

y -----> the numbers of cheeseburgers sold on Thursday

we know that

$x+y=417$ ----> equation A

$y=2x$ ----> equation B

Substitute the equation B in equation A and solve for x

$x+2x=417$

$3x=417$

$x=139$

Find the value of y

$y=2(139)=278$

therefore

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.

A jewelry stand sells 5 different pairs of earrings. The earrings sell for $12, $9, $6, $8, and $10.

Maslowich

The answer is $1.6

Step 1. Find the mean of all values (X = ?).
Step 2. Find the distance of all values from the mean (d1, d2, d3, d4, d5).
Step 3. Find the mean of distances (D).

x1 = $12
x2 = $9
x3 = $6
X4 = $8
x5 = $10

Step 1.
X = (x1 + x2 + x3 + x4 + x5)/5
= (12 + 9 + 6 + 8 + 10)/5
= 45/5
= $9

Step 2.
d1 = 12 - 9 = 3
d2 = 9 - 9 = 0
d3 = 9 - 6 = 3
d4 = 9 - 8 = 1
d5 = 10 - 9 = 1

Step 3.
D = (d1 + d2 + d3 + d4 + d5)/5
= (3 + 0 + 3 + 1 + 1)/5
= 8/5
= $1.6
