Answer:
7
Step-by-step explanation:
collect like terms
14=-a+3a
2a=14
dividing both sides
a=7
Answer:
C. 7h + 50 > 99
Step-by-step explanation:
She earns <u>more</u> than $99, so you know that the sign will be > (more than).
h is the number of hours, so to find how much she earns for working h hours at $7/hour, you multiply h by 7 --- 7h
She also earns an additional $50, which will be +50.
Therefore, the equation is: 7h + 50 > 99
Hope this helps :D
The answer is B) 2/13.
An easy way to figure this out is to find what the unsimplified probability would be:
Since there are 8 kings and queens in total, the number is:
8/52
But, since these are both even numbers, they can be simplified.
1/4 x 8 = 2
1/4 x 52 = 13
2/13
Since 13 is a prime number, the answer cannot be simplified anymore.
Answer:
Step-by-step explanation:
The different isotopes have different "half-lives" – the time it takes to lose half of its radioactivity. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity.
