You pay $14.82 for 1.5 pounds of ham. You buy 2.25 pounds of roast beef for $12.40 per pound. a. How much less does ham cost per

shutvik [7]

Answer:

A.) $2.52 less per pound. B.) $13.08 more

Step-by-step explanation:

A.) You pay $14.82 for 1.5 lbs of ham. You divide $14.82 by 1.5 lbs (14.82/1.5) to figure out how much you spend per pound of ham. You should get $9.88. Since you spend $12.40 per pound of roast beef, you subtract $9.88 from $12.40 ($12.40 - $9.88). You should get $2.52, which is your answer.

B.) Since you paid $14.82 for 1.5 lbs of ham, you already have this variable. Take the 2.25 lbs of roast beef and multiply it by $12.40 per pound (12.40*2.25). You then take that number ($27.90) and subtract it by $14.82 (27.90-14.82) and you should get your answer, $13.08.

Drag the tiles to the correct boxes to complete the pairs.

Elza [17]

Answer:

Part 1) -7 → $\dfrac{y^2-y+6}{-2(y+7)}$

Part 2) 3/2 → $\dfrac{y^2-2y+1}{2y-3}$

Part 3) 1 → $\dfrac{5y^2-6y+1}{-5(y-1)}$

Part 4) -1/4 → $\dfrac{y(y+5)}{4y+1}$

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

we know that

To find out the non permissible replacements for y, equate the denominator of each expression equal to 0.

step 1

we have

$\dfrac{y^2-2y+1}{2y-3}$

Equate (2y-3) equal to 0.

$2y-3=0$

solve for y

Adds 3 both sides.

$2y=3$

Divide both sides by 2.

$y=\dfrac{3}{2}$

therefore

3/2 is the non permissible replacement for y.

step 2

we have

$\dfrac{y(y+5)}{4y+1}$

Equate (4y+1) equal to 0.

$4y+1=0$

Subtract 1 both sides

$4y=-1$

Divide by 4 both sides

$y=-\dfrac{1}{4}$

therefore

-1/4 is the non permissible replacement for y.

step 3

we have

$\dfrac{5y^2-6y+1}{-5(y-1)}$

Equate -5(y-1) equal to 0.

$-5(y-1)=0$

Divide by -5 both sides

$y-1=0$

Adds 1 both sides

$y=1$

therefore

1 is the non permissible replacement for y.

step 4

we have

$\dfrac{y^2-y+6}{-2(y+7)}$

Equate -2(y+7) equal to 0.

$-2(y+7)=0$

Divide by -2 both sides

$y+7=0$

Subtract 7 both sides

$y=-7$

therefore

-7 is the non permissible replacement for y
