Write 83 as a sum of tens and ones
Hoochie [10]
Well,

We can see that there are 8 10's and 3 1's.  So we can write 8 10's followed by 3 1's and join them with addition symbols.

83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1

Answer:  

1st Question

A. 85

2nd Question  

B. 71

Step-by-step explanation:

1st Question

{90 + 94 + 96 + 90} = 370/4 = 92.5

{95 + 99}                  = 194/2 = 97

{87 + 75 + 82 + 85} = 329/4 = 82.25

{71}                =  71/1               = 71

.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175  Rounded-up = 85

___________________________________________________

2nd Question  

.10(95) +.20(80) +.50(67) +.20(60) = 71

Can get some help on 2,4,22, 42 and 50 please
Fittoniya [83]

Answer:

2. zeros

4. difference

22. 79,158.5

42. 0.0099

50. 4.37

Step-by-step explanation:

2. Only adding 0s after a decimal point does not change the value.

4. Since you are subtracting then you estimate difference.

22. Add each number using place value.

75285

        2

  3971

        0.5

__________

79258.5

42. 0.01 is really 0.0100. If you subtract 0.0001 then it is like subtracting 100-1 = 99 but in the decimal place. So it becomes 0.0099.

50. Subtract by lining up decimal places. Then move place values to subtract.

      9.00

    - 4.63

----------------

      4.37
