Answer:

20 + -9 + 8 + -7

Step-by-step explanation:

A epression DOES NOT have a equal sign,  =

20-9+8-7 = 12

20 + -9 + 8 + -7

to check -->

20 +-9 + 8 + -7

20 + -9 = 20 - 9 = 11

11 + 8 = 19

19 + -7 = 19 - 7 = 12

So therefor it would be

20 + -9 + 8 + -7

Barnaby decided to count the number of ducks and geese flying south for the winter. On the first day he counted 175 ducks and 63
olga_2 [115]

Answer:

13,125 ducks

Step-by-step explanation:

The ratio of ducks:geese on the first day was:

175:63

On the last day (end of migration), he counted 4,725 geese.

To find the number of ducks using the same ratio, we are first going to divide 4,725 by 63 to find what number all the ducks and geese multiplied by:

4,725/63 = 75

The geese multiplied by 75. This means the ducks also multiplied by 75:

175*75 = 13,125

Barnaby counted 13,125 ducks.

Hope it helps (●'◡'●)

Answer for brainlest and 25 points
nordsb [41]

Answer:

Order from greatest to least: 10.5, 3\pi +1, \sqrt{105}

Step-by-step explanation:

step 1 simplify each number

3π + 1  = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

\sqrt{105} =10.2469507

*round to the nearest tenth*

\sqrt{105} =10.2

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = \sqrt{105}

Your answer is

10.5 , 3\pi + 1, \sqrt{105}
