7.3 ------ 8.1 8.5 8.9

let us try to find the common difference here using last three terms

8.5-8.1=0.4

8.9-8.5=0.4

so it is clear that common difference is 0.4

so adding 0.4 to 7.3 will give the next term

7.3+0.4=7.7

Answer : missing number is 7.7

malfutka [58]

Step-by-step explanation:

Since we have given that

Number of muffins Diana sold at the bake sale = 336

Number of muffins Bob sold at the bake sale = 287

Now, here we are using the method of estimation i.e. rounding the integers to nearest ones.

By estimation, we get

Number of muffins Diana sold at the bake sale = 340

Number of muffins Bob sold at the bake sale = 290

WHAT IS 18 TONS 42 POUNDS DEVIDED BY 3
Alecsey [184]

A ton is 2,000 pounds so multiply 2,000 x 18

2,000 x 18 =  36,000 pounds, now add the 42 pounds to the 36,000

36,000 + 42 = 36,042 pounds. Now divide 36,042 by 3

36,042 ÷ 3 = 12,014

Your answer is 12,014 pounds

If you need your answer in tons it's 6.007 tons

Calculations for pounds to tons

12,014 ÷ 2,000 = 6.007

Hope this helps. :)
