In this problem, we let x be the number of half gallons of milk the store bought, and x-12 be the remaining half gallonsWe use the equation profit = revenue-cost
 88.08=4.02(x-12)-2.60x88.08=4.02x-48.24-2.6x1.42x=88.08+48.24=136.32x=136.32/1.42=96Hence, the number of half gallons of milk the store bought is 96

Zinaida [17]

Answer:

1 1/4

Step-by-step explanation:

For the strawberries, we will have to multiply 3 by 1/4 to get the total amount of strawberries used.

1/4 * 3 = 3/4

For the blueberries, we will have to multiply 2 by 1/4 to get the total amount of blueberries used.

1/4 * 2 = 2/4

Simplify that to get 1/2

Now we need to add 3/4 and 1/2

3/4 + 1/2 = 5/4

Simplify that and we get our answer;

1 1/4

Use the diagram to answer the following questions.125°Lx2X+10NmZNPMdegreesmZLPMdegrees
lutik1710 [3]

For the angle MPN we know that is oposite to the angle QPL so the will be equal so:

\angle MPN=125º

Now with the value of MPN we can made an equation for x so:

125=2x+10

and we solve for x

\begin{gathered} 125-10=2x \\ \frac{115}{2}=x \\ 57.5=x \end{gathered}

and the angle LPM will be the complementari angle of 125 so:

\begin{gathered} \angle LPM=180-125 \\ \angle LPM=55º \end{gathered}
