6 0

Answer:

19 or 21.

Step-by-step explanation:

I swear.

5 + 5 = 10

10 + 5 = 15

15 + 4 = 19

________________

9 + 9 = 18

18 + 10 = 28

28 - 5 = 23

There are two nines so

23 - 2 = 21

Helen [10]

Answer:

10

Step-by-step explanation:

This is the answer because:

1) First, insert all the numbers into the expression

Expression: I -2(2) + -3(2) I

-2 x 2 = -4

-3 x 2 = -6

Therefore the answer is 10

What id the sum of 2'8" + 1'6"
lidiya [134]
Interesting question about feet and inches.  The best way to solve this problem is to ask yourself how many inches are in a foot.  Since there are 12 inches in every foot then the length of 2'8" can be written as (2*12)" + 8".  Which is 24+8 or 32 inches.  The second number (1'6") can be written as (1*12)"+6" which is 18 inches.  32 + 18 = 50 inches.  Or, if you want to change this back into feet and inches just divide it by 12.  50/12 is 4 R. 2.  So 4'2".

What is the sum of the first 10 positive integers?<br><br> A) 55<br> B) 50 <br> C) 100<br> D) 95
olga2289 [7]
The correct answer here is A) 55. This is because a positive integer is defined as any number greater than 0 and has no decimals/ fractions in it. Therefore, you would add 1+2+3+4+5+6+7+8+9+10, yielding 55 as your answer.
