Answer:

b = 141

Step-by-step explanation:

b − –573 = 714

Subtracting a negative is adding

b + 573 = 714

Subtract 573 from each side

b − 573+573 = 714-573

Show me how to do the problem, hamza bought 8 gallons of brown paint to paint it is kitchen and dining room unfortunately, when
Karolina [17]

Answer:

1 gallon.

Step-by-step explanation:

The quantity of brown paint is 8 gallons.

To get the shade of brown paint he desired, \frac 1 4 gallon of white paint required to be mixed with 2 gallons of brown paint.

Here, Hamza wants  to lighten the 8 gallons of brown paint, so, by using the elementary method,

For 2 gallons of brown paint, he required \frac 1 4 gallon of white paint.

So, for 1 gallon of brown paint, he required \frac 1 {4\times2} gallon of white paint.

Now, for 8 gallons of brown paint, he required \frac 1 {4\times2}\times 8=1 gallon of white paint.

Hence, Hamza needs to buy 1 gallon of white paint to light the 8 gallons of brown paint.

If 3 boys can build 4 snowmen in 24 minutes how many will 9 boys finish building in an hour
andrey2020 [161]

Answer:

The boys can build 30 snowmen in an hour

Step-by-step explanation:

  Extracting the key information from the question:-

*** 3 boys can build 4 snowmen I 24 minutes.

*** 9 boys are to build  snowmen.

*** How many snowmen can be built by the 9 boys in an hour.

  Firstly, since 3 boys can build four (4) snowmen in 24 minutes, we need to convert one hour to minutes.

   60 minutes = 1 hour.

   Now, since three boys can build four (4) snowmen in twenty four (24) minutes, we need to know or find out how many snowmen  that none boys can build in the same time if they all work at the same rate as the three boys.

     

3 boys ------------- 4 snowmen (24minutes)

9 boys -------------- ? snowmen (24 minutes)

= 9/3  × 4

= 36/3

= 12 snowmen (24 minutes).

Now, 9 boys can build 12 snowmen in 24 minutes. All we now need to do is to determine or figure out  how many snowmen that the nine boys can build within an hour of work (60 minutes).

  Since nine boys can build 12 snowmen in 24 minutes, the number of snowmen that they can build in an hour (60 minutes) is:

(9 boys) 24 mins ------- 12 snowmen

(9boys) 60 mins --------- ? snowmen

  = 60/24  ×  12

 = 720/24

 = 30 snowmen

 Therefore, 9 boys can build 30 snowmen in one hour if they all build at the same rate as the initial three boys.
