Step-by-step explanation:

30% off of $612 is $428.4

John is 3 years older than Jim. Jim is 4 years less than twice David’s age. How old are the three boys if their ages add up to 3
gulaghasi [49]

Answer:

15  years , 12  years , 8 years.

Step-by-step explanation:

Given:

John is 3 years older than Jim.

Jim is 4 years less than twice David’s age.

Ages of three boys add up to 35.

Question asked:

How old are the three boys?

Solution:

Let age of David = y

Let age of Jim = x

Then age of John will be = x + 3

As Jim is 4 years less than twice David’s age

Equation will be  , x = 2y - 4

Multiplying both side  by 2

                       = 2x = 4y - 8  (let equation 1 )

As ages of three boys add up to 35.

Equation will be,x + (x + 3) + y = 35

                           = 2x + 3 + y = 35

Subtracting both side by 3

                           =   2x + y = 32

                          = 2x = - y + 32  (let equation 2 )

subtracting equation 1 and 2,we get

                           =  2x = - y + 32

                          =   2x = 4y - 8

                          =  0 = - 5y + 40

                          = 5y = 40

dividing both side by 5

                              = y = 8 (David ages)

Then  ( age of Jim)  x = 2y - 4

                                 x = 2 \times8 - 4

                                    = 16 - 4

                                    = 12 years

Then age of John will be, x + 3

                                            = 12 + 3

                                            = 15 years

Thus, age of John = 15 years

Age of Jim = 12 years

Age of David = 8 years

slava [35]

Answer:

a. 3/5 liters per hour

b .06 hours

Step-by-step explanation:

Change 40 minutes to a fraction of an hour

40 minutes/ 60 minutes = 2/3 hour

It takes 1 2/3 hours to fill the container

Changing to an improper fraction

(3*1+2)/3 = 5/3 hours

We want liters per hour

1 liter per 5/3 hours

1 ÷ 5/3

Copy dot flip

1 * 3/5 = 3/5 liters per hour

Change 100 ml to liters

We know 1000 ml  = 1 lt

100 ml * 1 lt/1000 ml = .1 lt

So 100 ml = .1 lts

.1 lt * 3/5 lt per hour

Changing the fraction to a decimal

.1 lt * .6 lt per hour

.06 hours

Hi please can you help me this is a new topic and I’m very confused
olchik [2.2K]

Answer: the large jar is cheaper

Step-by-step explanation:

If you divide the £1.54 by 440g and £1.26 by 340g, you'll find which one is cheaper per gram :

1.54/440 = 0.0035

1.26/340 = 0.0037

So, by comparing both prices/gram, you've found that the large jar is cheaper.
