Answer: I’m pretty sure it’s $2.25.

Step-by-step explanation: Well first you’d want to know how much each egg costs. To do that you would do $1.50 divided by 12 and you’d get $0.125. Then you would multiply that by 18. Once you do that, you get $2.25.

Answer:

$2.25

Step-by-step explanation:

A dozen = 12 eggs = $1.50

1 egg = 1.5 / 12 = 0.125

18 eggs = 0.125 * 18

= $2.25 = 1 1/2 dozen

The sum of two.number is.24. the.sun.of the square.of the two.nunber is 306. what is the product.of the two.number

tresset_1 [31]

A) x + y = 24
B) x^2 + y^2 = 306

A) x = 24 -y
Then substituting this into B)
(24 - y)^2 +y^2 = 306
576 -48y +y^2 + y^2 = 306
2 y^2 -48y + 270 = 0
x1 = 15
x2 = 9

I'm confused on how to go about solving this, I got to this part:

SCORPION-xisa [38]

Answer:

(3, -4, 6)

Step-by-step explanation:

The last equation has 2 variables

If we double the first equation and subtract the second one from it, we get rid of y and then comparing the new equation with the last one we can easily solve it

Step 1

2(2x + y + 3z) = 2*20
4x + 2y + 6z = 40

Step 2

4x - x + 2y - 2y + 6z - (-z) = 40 - (-11)
3x + 7z = 51

Step 3

3x + 7z - (3x - 2z) = 51 - (-3)
7z + 2z = 54
9z = 54
z = 6

Then finding x

3x - 2*6 = -3
3x = 12 - 3
3x = 9
x = 3

Then finding y using the first equation

2*3 + y + 3*6 = 20
y + 24 = 20
y = -4

The answer:

(3, -4, 6)
