2/3(x + 7) = 10. Divide each side by 2/3.

x + 7 = 15. Subtract each side by 7.

x = 8

Mo’s farm stand sold a total of 165 pounds of apples and peaches. She sold apples for $1.75 per pound and peaches for $2.50 per
9966 [12]

Answer: 65 pounds of Peaches were sold.

Step-by-step explanation:

Let the number of pounds of  Peaches sold                  = X pounds

Therefore the pound of apple sold                                 = (165 - X ) pounds

Total pounds of apple and peaches sold                       = 165 pounds

Sale made on Peaches at the cost of $2,50 per Peache = $2.50X

sale made on apple sold at the cost of $1.75 per apple  = $1.75(165 - x )

Total sale made on the sale of both Peaches and apple = $337.50

Therefore , open the bracket, add everything together and equate to the total sale made which is $337.50

 we now have

  2.50x + 1.75( 165 - x ) = 337.50

  2.50x + 1.75 x 165 - 1.75x = 337.50

  2.50x + 288.75 - 1.75x = 337.50

collect like terms

2.50x - 1.75x = 337.50 - 288.75

           0.75x = 48.75

divide through by the coefficient of x which is 0.75

                   x = 48.75/0.75

                      = 65pounds .

Therefore, Mo's farm sold 65 pounds of Peaches.

Check ;

  65 x 2.50 = $162.5

   subtract 65 from 165 to get the pound of the appel

   165 - 65 = 100 pounds of apple was sold.

 now multiply 100 x 1.75

                  = $175

Now add the two together to give the total sale ,

                $162.5 + $175  = $337.50.

All the cubes below have a different image on each side.
-BARSIC- [3]

Answer:

  • <u>Figure G</u>

Explanation:

The figure labeled A cannot be because the cross and the line are not oriented in  the same relative position as in X.

The figure labeled B cannot be because the line and the the image with the three lines are not oriented in the same relative position as in X.

You cannot tell about the figures labeled C because you do not see the images of the cross and the line.

The figure labeled E cannot be because the image with the three lines is not oriented in the same relative positiion with respect to the other two as in X.

You cannot tell about the figure labeled F because the image of the cross and with the three lines are not shown.

The figure labeled G is correct: you can just rotate the cube labeled X 90 degrees counterclockwise about a vertical axis that passes through the center of the cube and get the cube labeled G.

Solve the equation. Round to the nearest hundredth. Show work.
Elis [28]

Answer:

The value of x = 0.41

Step-by-step explanation:

∵ 6e^{2x}-5e^{x}=6

Let e^{x}=y

∴ e^{2x}=y^{2}

∴ 6y² - 5y = 6

∴ 6y² - 5y - 6 = 0 ⇒ factorize

∴ (3y + 2)(2y - 3) = 0

∴ 3y + 2 = 0 ⇒ 3y = -2 ⇒ y = -2/3

∴ 2y - 3 = 0 ⇒ 2y = 3 ⇒ y = 3/2

∵ y=e^{x}

∴ e^{x}=\frac{-2}{3} ⇒ refused

  (e^{ax} never gives -ve values)

∵ e^{x}=3/2 ⇒ insert <em>ln</em> in both sides

∵ lne^{ax}=axlne=ax ⇒ <em>ln</em>(e) <em>= 1</em>

∴ xlne=ln(3/2)

∴ x = ln(3/2) = 0.41
