Here is deeper explanation:
1. a(5+b) is like a times 5 + a times b. The () means it needs to be multiplied by the number next to it(example: a(b-c), so a•b-a•c [• means times or multiply])
2. That's it!

If 9x is an odd integer, represent the next odd integer as the algebraic expression in x.
Luba_88 [7]
Any odd integer can be expressed as 2n+1, for some integer n.

The next odd integer, after 2n+1, is 2n+1+2=2n+3



thus 9x=2n+1, means that 9x-1=2n,   so n=(9x-1)/2

the next odd number after 2n+1 is 2n+3= 2* (9x-1)/2+3=9x-1+3=9x+2


Remark : this result could also have been found directly.


Answer: 9x+2

Just divide the original cost for one pound by 4 for each meat.
4.25 divided by 4. if it makes it any easier, 425 divided by 400 because you just move the decimal over and you will get the same result. 
2.85 (or 285) divided by 4 (or 400).
then add the original cost per pound for each and then subtract turkey from beef.

Our hearts beat approximately 70 times per minute. Express in scientific notation how many times the heart beats over a lifetime
earnstyle [38]

Answer:

2.69 x 10^{9}

Step-by-step explanation:

We are given the heart's speed - 70 bpm

We count the number of minutes in 73 years :

  • 1 year = 365 days
  • 1 day = 24 hours
  • 1 hour = 60 minutes
  • 73 x 365 x 24 x 60 = 38,368,800 minutes

We multiply the heart's bpm with 73 years worth of minutes

38,368,800 x 70 = 2,685,816,000

Write the number in scientific notation = 2.68581 x 10^{9} ≈ 2.69 x 10^{9}
