Each computer will cost $1,856 and they will have 50 cents left over.


EXPLANATION:


So First you have to add up each total

$1,930( Mr. Datz) + $1,783(Ms. Datz)= $3,713

Then you divide the total by two

$3,713/ 2= 1,856.50


I believe that this is correct. Hope that you get this right! And that my explanation wasn’t too confusing.

Solve the following question
emmasim [6.3K]

Answer:

16 and 4

Step-by-step explanation:

Let (x+y) =20 and (x-y)=12 then:

Isolate for x in each equation

   x=20-y and x=12+y

Set the equations to equal each other since the value of x should be the same for both

   20-y = 12+y

Rearrange so that y is on one side and the numbers are on the other

   8 = 2y

   y= 8/2

   y= 4

Now  substitute the y- value back into either of the original equations

   x+y= 20

   x+4 = 20

Rearrange and isolate  x

   x = 20-4

   x = 16

So the two values are 16 and 4

The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?
xeze [42]

Answer:

222 boys

Step-by-step explanation:

Let x = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

\frac{5}{6+5}x = 185 (number of girls in ninth grade)

\frac{5}{11}x = 185

x=407

To find for the number of boys, we can use substitution:

\frac{6}{6+5}x = \frac{6}{11}(407)

=222

∴ There are 222 boys in the class.

Hope this helps :)

AfilCa [17]

Answer:

Sakura spoke for 2 minutes in Hungarian and for 3 minutes in Polish

Step-by-step explanation:

So make the variables.

Hungarian = x

Polish = y

x  and y are the amount of time she spent in minutes.

x + y = 5

150x + 270 = 190y

x = 5 - y

750 - 150y + 270 = 190y

1020 = 340y

y = 3

x = 2
