3 consecutive odd integers such that the sum of twice the first and three times the second is 55 more than twice the third

den301095 [7]

Answer:

Consecutive odd integers are 19 , 21 & 23

Step-by-step explanation:

Let the first 3 consecutive odd intergers be x , (x + 2) and (x + 4).

According to the question,

$2x + 3(x + 2) = 2(x + 4) + 55$

$= > 2x + 3x + 6 = 2x + 8 + 55$

Eliminating 2x from both the sides,

$= > 3x + 6 = 63$

$= > 3x = 63 - 6 = 57$

$= > x = \frac{57}{3} = 19$

So, the consecutive odd integers are = 19 , 21 & 23.

I really need help on this question! Thank you!

Answer:

Step-by-step explanation:

We know the following:

$OE=5\\\\FG=4\\\\EF=8\\\\$

so the segment EF is equal to

$EF=EG+GO+OF\\\\$

and here we can do a trick :)

$EF=(EG+GO)+GO+(OF+OG)-2GO\\\\$

you see it's the same

$EF=EO-GO+FG\\\\$

now we plug the values given

$8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1$

so it's option A

Step-by-step explanation:

1. 8 (x + 2) = 56 Distribute the 8

2. 8x + 16 = 56 Subtract 16 from both sides

3. 8x = 40 Divide both sides by 8
