Answer:

The second one is 81300, The third one is 294

Step-by-step explanation:

Question 2

x*5*25*4/5, if x = 813

813*5*25*4/5

4065*25*4/5

101625*4/5

406500/5

81300

Question 3

3(x + 9) - 2(x + 4), if x = 275

3(275 + 9) - 2(275 + 4)

3(284) - 2(279)

852 - 558

294

The third and the fourth picture are the same problem, right?

Hope this helped you!!

Find the average rate of change.
alina1380 [7]

The average rate of change = 1.59 ≈ 2

The average rate of change can be calculated by

1) The first one = \frac{3 + 0}{2} = 1.5

2 ) the second can also be solved by ; 8 + 2/ 2 = 5

3 ) the third one will be 20 + 6 / 2 = 13

4) 8.5

5) 12.5

To calculate the average rate of change

we will first add all the distance

Adding all the distance we will get the sum = 3 + 8 + 20 + 10 + 10 = 51

The total time = 2 + 6 + 9 +15 = 32

Thus the average rate of change = 51 / 32 = 1.59

Three less than one-fourth of the product of eight thirds and nine. Please write equation, then solve.
kenny6666 [7]
Put simply, you have to work backwards in making the equations. Start with the product of 8/3 and 9.
\frac{8}{3}*9

 Next take 1/4 of that. This can be done in two ways, either multiplying by 1/4:
(\frac{8}{3}*9)*\frac{1}{4}

, or dividing everything by 4.
(\frac{8}{3}*9)/4

Finally, subtract three.

The final equation would read:
((\frac{8}{3}*9)*\frac{1}{4})-3



Using PE(M/D)(A/S), we'd start with \frac{8}{3}*9

3 and 9 cancel out to be 1 and 3, leaving us with \frac{8}{1}, or 8, and 3 and this part of the equation reading 8*3, which is 24.

The next step is \frac{24}{4}, which is 6.

Lastly we subtract 3 from six, leaving us 3.
