Someone please help me on this math problem!

Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19       <em>add 29 to both sides</em>

10y = 7y + 48          <em>subtract 7y from both sides</em>

3y = 48      <em>divide both sides by 3</em>

y = 16



3x + 7 = 5x - 21            <em>subtract 7 from both sides</em>

3x = 5x = -28         <em>subtract 5x from both sides</em>

-2x = -28     <em>divide both sides by (-2)</em>

x = 14

soldi70 [24.7K]
Hey there! The answer is 7x + 4y < 40

Let's first rearrange our data in a more structured way.

x represents a box of wings which has a cost of $7.00. Therefore the total cost of the boxes is 7x.

y represents a tray of nachos which has a cost of $4.00. Therefore the total cost of the trays is 4y.

The sum of the costs of trays and boxes, which is (7x + 4y) must be smaller than $40.

Now we can set up the inequality.
7x + 4y < 40
