Natural numbers, whole numbers, integers, and rational numbers
10. 2 consecutive integers....x = smaller one, x + 1 = larger one
2(x + 1) = 3x - 15
2x + 2 = 3x - 15
2 + 15 = 3x - 2x
17 = x
x + 1 = 17 + 1 = 18
so ur 2 numbers are : 17 and 18
===========================
11. 2 consecutive odd integers....x = smaller one and x + 2 = larger one
5(x + 2) = 8x + 1
5x + 10 = 8x + 1
10 - 1 = 8x - 5x
9 = 3x
9/3 = x
3 = x
x + 2 = 3 + 2= 5
so ur 2 numbers are : 3 and 5
=========================
12. 2 consecutive even integers....x = smaller one.....x + 2 = larger one
1/2x = x + 2 + 2
1/2x = x + 4
1/2x - x = 4
1/2x - 2/2x = 4
-1/2x = 4
x = 4 * -2
x = -8
x + 2 = -8 + 2 = -6
so ur 2 numbers are : -6 and -8
Answer:
8/21
Step-by-step explanation:
The total job is 1
Mike has done 1/3 and Dena has done 2/7 of the job We still need to do x of the job to complete it
1/3 + 2/7+ x = 1
We need to get a common denominator 3*7 = 21
Multiply each side by 21
21(1/3 + 2/7+ x) = 1*21
21(1/3) + 21*(2/7)+ 21x = 21
7+ 3*2 +21x =21
7+6+21x = 21
13+21x = 21
Subtract 13 from each side
13-13+21x=21-13
21x = 8
Divide each side by 21
21x/21 = 8/21
x = 8/21
We need to complete 8/21 of the job
I believe the answer is 1848.
Hi there
just keep dividing by 2 tell you get to the 10th term
that's one way of doing it
32, 16, 8, 4, 2, 1 , 1/2 , 1/4 , 1/16, 1/32
1/32 is the 10th term
