We know that the problem statement states that the number of ice cream sandwiches eaten together by Molly and Torry is 12.

Since Molly ate 5 and Torry ate n ice cream sandwiches, we can represent this in the equation below...

5 + n = 12

You start at (3, -3). You move down 1 unit and left 2 units. Where do you end?
Maslowich

Your end position is 1, -4)

<h3>How to determine your end position?</h3>

The start position is given as

Start = (3, -3)

The movement can be represented using the following translation rule

(x, y) = (x - 2, y - 1)

When the above translation rule is applied, we have:

End = (3 - 2, -3 - 1)

Evaluate the difference

End = (1, -4)

Hence, your end position is 1, -4)

4x + 5y = 102<br> 7y + 5y = 126
galina1969 [7]

Answer:

hope you like my question

Step-by-step explanation:

Hi -

What you want to do here is solve the equation by substitution.

To do that, you solve one of the equations for y. then plug that into the other equation so you have an equation with only x as the variable.

1) Solve either equation for y. Lets go with the first one:

4x+5y=102

Subtract 4x from each side:

5y=102-4x

Divide both sides by 5

y=(102-4x)/5

2) Plug this value for y into the other equation we started with:

7x+5y = 126

7x + 5((102-4x)/5) = 126

3) Solve the resulting equation for x.

Since we are multiplying and dividing (102-4x) by 5 the 2 5s cancel each other out

7x + 5((102-4x)/5) = 126

7x + 102 - 4x = 126

Combine the 2 x terms:

3x+102=126

subtract 102 from each side:

3x = 24

Divide both sides by 3:

x=8

Once we have a value for x, we can plug that number into either one of our starting equations to solve for y.

4x + 5y = 102; if x = 8

32+5y = 102

subtract 32 from each side:

5y = 70

Divide both sides by 5:

y = 14

So x = 8 and y = 14.

You can check your work by plugging these numbers both into your 2 initial equations.

4x+5y=102; 4*8+5*14 = 102

7x+5y=126; 7*8 +5*14 = 126

27, first you take 66-12 bc that is both of their ages, and then I divided that by 2 since it’s twice jasmines age. Hope this helps and would appreciate a Brainly :)
