If you start with Malvin’s age, take half of it, increase that result by 5, then divide by 3, and finally double that, you get 8
Kisachek [45]

Answer:

24 years old

Step-by-step explanation:

Let Malvin's age be x.

  • x / 2
  • x / 2 + 5 = 5x / 10  [ By taking the L.C.M.]
  • ( 5x / 10 ) * ( 1 / 3 ) = 5x / 30   [ Multiply with the reciprocal of 3 ]
  • ( 5x / 30 ) * 2 = 5x / 15

Now let's solve the equation,

5x / 15 = 8

       5x = 8 * 15

       5x = 120

         x = 120 / 5

         x = 24

Therefore, Malvin is 24 years old.

Ely has a bag of 42 strawberries. She eats 16 strawberries. How many cherries does she have left. The next day she goes to the s
juin [17]

The number of cherries left is 26

Ely has 54 strawberries now

<em><u>Solution:</u></em>

Given that, Ely has a bag of 42 strawberries. She eats 16 strawberries

To find: Number of cherries left

From given,

Total number of strawberries = 42

Number of strawberries eaten = 16

Therefore,

Number of cherries left = Total number of strawberries - Number of strawberries eaten

Number of cherries left = 42 - 16 = 26

Thus, number of cherries left is 26

<em><u>The next day she goes to the store and buys 28 more cherries</u></em>

Number of cherries bought = 28

Therefore,

Total number of cherries she has now = number of cherries left + Number of cherries bought

Total number of cherries she has now = 26 + 28 = 54

Thus she has 54 strawberries now
