Answer:

Step 3

Step-by-step explanation:

Given

(5 - 2)^ 2 + 23 * 4

Required:

Determine the first step where she made mistake

Her Step 1:

(3)^ 2 + 23 * 4 --- This is correct because she solved the bracket first

Her Step 2:

9 + 23 * 4 --- This is correct because she solved 3^2 as 9

Her Step 3:

9 + 9 * 4 --- This is incorrect because 23 * 4 is not equivalent to 9 * 4

Hence, her first mistake is in step 3.

The correct expression would have been

9 + 92

Then

= 101

For this problem what I did was that I multiplied 100 x 34 = 3,400 and subtracted that answer with 5,086. The answer I got was 1
inessss [21]

Answer:

The answer rounded to the nearest whole number is 1729

Step-by-step explanation:

Set it up like this:  Percent in fraction form = x over total

So:  34/100  = x/5086

You then multiply:   34 x 5086 = 172924

Then divided that number by 100:   172924 divided by 100 = 1729.24

Then round the number to the nearest whole number:   1729

Hope this helps good luck!
