Answer:

Gabriela's new average would be

Step-by-step explanation:

First, if her average on three tests is 85, and she receives 100 on her last two tests, the first step would be to add 85, 100, and 100; Her previous average and the grades she would receive on her last two tests.

85+100+100=285.

The next step would be to count how many numbers we added to receive our sum. We added three. Because of this, we have to divide the sum by three to get Gabriela's average.

285÷3=95.

Therefore, Gabriela's new average would be 95.

0.6(4-2x)=20.5-(3x+10)
solong [7]

The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5

<u>Solution:</u>

Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )

We have to solve the above given equation for x.

Now, take the equation  

\rightarrow 0.6(4-2 x)=20.5-(3 x+10)

We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction

On solving the brackets, we get

\rightarrow 0.6 \times 4-0.6 \times 2 x=20.5-3 x-10

Now multiplication is given preference

\rightarrow 2.4-1.2 x=10.5-3 x

\rightarrow 3 x-1.2 x=10.5-2.4

Now subtraction is done

\rightarrow 1.8 \mathrm{x}=8.1

Now division is performed

\rightarrow x=\frac{8.1}{1.8}=4.5

Hence, the value of x is 4.5

At Elisa's Printing Company LLC there are two kinds of printing press: Model A which can print 70 books per day and Model B whic
NeX [460]

Answer:

Number of Model A press = 9 and Number of Model B press = 5

Step-by-step explanation:

Number of books Model A can print per day = 70

Number of books Model B can print per day = 55

Let x be the number of Model A press and y be that of Model B press.

Total number of printing presses = 14

x + y = 14  ----------------1

Total number of books printed per day = 905

70x + 55y = 905-------2

Putting y = 14 - x in equation 2, we get:

70x + 55(14 - x) = 905

15x = 135

x = 9

y = 14 - 9 = 5

Hence number of Model A press is 9 and that of Model B press is 5.
