You can represent an odd integer whith the expression 2n+1, where n is any integer . Write and solve an equation to find three c

oksian1 [2.3K]

Any odd number can be expressed by 2n+1.

For example,

2n+1=111
2n=110
n=110/2=55

means that 111 is 2n+1 for n=55

Thus if an odd number is 2a+1, the next few numbers are as follows:

2a+1, 2a+2, 2a+3, 2a+4, 2a+5

So 2a+1, 2a+3 and 2a+5 are 3 consecutive odd numbers.

Back to our problem:

three consecutive odd numbers whose sum is 63 are:

(2n+1)+(2n+3)+(2n+5)=63

6n+9=63

6n=63-9=54

n=54/6=9

2n+1=2*9+1=18+1=19, the 2 next odd numbers are 21 and 23

Answer: 19, 21, 23

Select the graph for the solution of the open sentence. Click until the correct graph appears.

I am Lyosha [343]

It would be the last one. The dots must be open and x must move to the right.

Use the percent proportion

21 x
—— = ——
100 300

to solve :
21 x 300 = 6300
6300 ÷ 100 = 63

Answer = 63 of Elmer’s shells are fossilized snail shells :)

Find the length of UC on the attached diagram. Thank you!

ValentinkaMS [17]

<h2>Answer </h2>

The length of UC is 18

<h2>Explanation </h2>

First we are going to find the length of JN; then we are subtracting from it the length of JU plus the length of CN.

We can infer from our picture that JN is 82 + 105, so JN = 187

We can also infer that JU = JH + HU

JU = 22 + 96

JU = 118
