Answer:

x = 7/13, y = 8/26

Step-by-step explanation:

3x-2y=1 ...Equation 1 -2x+3y=2 ...Equation 2 Solve this equation.

3x - 2y =>1.....Equation 1

2x + 3y => 2......Equation 2

We solve using Elimination

We multiply Equation 1 by 3 and Equation 2 by 2 to Eliminate y

9x - 6y => 3.....Equation 4

4x + 6y => 4.......Equation 5

We Add Equation 4 and 5

13x = 7

x = 7/13

We substitute 7/13 for x in Equation 1

3x - 2y =>1.....Equation 1

3(7/13) - 2y => 1

21/13 - 2y = 1

21/13 - 1 = 2y

y =>21/13 - 1/2

y => 8/13 ÷ 2

y = 8/13 × 1/2

y = 8/26

Gina made 9350ml chicken noodle soup she packed 1.8l of soup in her kids lunches she froze the rest of the soup how many ml of s
Andre45 [30]

Answer:

<u>7550 ml</u> of soup Gina have left to freeze.

Step-by-step explanation:

Given:

Gina made 9350ml chicken noodle soup, she packed 1.8l of soup in her kids lunches.

She froze the rest of the soup.

Now, to find the ml of soup Gina have left to freeze.

<u><em>The total quantity of soup Gina made = 9350 ml.</em></u>

Quantity she packed for lunches = 1.8 l.

Now, we convert l into ml by using conversion factor:

1 l = 1000 ml.

1.8 l = 1.8 × 1000 ml.

1.8 l = 1800 ml.

<u><em>Thus, the quantity she packed for lunches = 1800 ml.</em></u>

Now, to get the ml of soup Gina have left to freeze we subtract the quantity she packed for lunches from the total quantity of soup she made:

9350\ ml-1800\ ml\\\\=7550\ ml.

Therefore, 7550 ml of soup Gina have left to freeze.

lubasha [3.4K]
A.) Yes you can, the expression would be (2.95 x Y) + 4 = X
B.) (2.95 x 24) + 4 = $74.80
C.) (2.95 x 57) + 4 = X
2.95 x 57 = 168.15 + 4 = 172.15
so basically they can buy 57 books without going over $175

Brrunno [24]

Answer:

-125

Step-by-step explanation:

Step 1: Find g(-1)

g(x) = -5x²

g(-1) = -5(-1)²

g(-1) = -5(1)

g(-1) = -5

Step 2: Find g(-5)

g(-5) = -5(-5)²

g(-5) = -5(25)

g(-5) = -125
