It would be 11 + 12 = 23 atomic mass units.
(electrons have about a mass of 5.489×10−4<span> atomic mass units, so their mass would be negligible in this calculation).

She spent $36 on the shirts. She spent $51 total.
You take 3(12) which = 36
Then you add 36+15 and get $51.
You need to simplify it by 8
Each multiple choice is worth 4 points, and X is the number of questions he get's right. For example, he gets 3 right: 4 x 3 = 12 points in total.
The same goes for the <span>word problems. Y represent the </span><span>the number of correct answers so, for example: he gets 4 right and each one is worth 8 points: 8x4
</span>
Since he needs to have a least 50 points, that means that he can have 50 or more than that. That can be written as: <span>≥
So, as i explained, the only possible option is D.</span>
<span> 4x + 8y ≥ 50 </span>
Answer:
<u><em>26 2/3 inches</em></u>
Step-by-step explanation:
<em><u>P=4s</u></em>
P= 4 × 6 2/3
P= <em><u>26 2/3 inches</u></em>
