Answer:
2x = 58 Step-by-step explanation:
x= 29
29+ y = 54
y = 54 - 29
y = 25
Check
29+25=54 √
29 - 25 = 4 √
Answer:
50d+35c= total cost
Step-by-step explanation:
50 cents for a donut, so 50 * d = total cost for donuts
35 cents for a cookie, so 35*c = total cost for cookies

<em>Question:</em>
<em>Haydin chooses a jersey at random and then replaces it. He then selects a second jersey at random. What is the probability that Haydin selects a striped jersey both times. 2 are striped,5 are colored and 3 are white.</em>
Answer:
![Probability = 0.04](https://tex.z-dn.net/?f=Probability%20%3D%200.04)
Step-by-step explanation:
Given
![Striped = 2](https://tex.z-dn.net/?f=Striped%20%3D%202)
![Colored = 5](https://tex.z-dn.net/?f=Colored%20%3D%205)
![White = 3](https://tex.z-dn.net/?f=White%20%3D%203)
Required
Determine the probability that both selections are stripped
This is calculated as:
![Probability = P(Stripped) * P(Stripped)](https://tex.z-dn.net/?f=Probability%20%3D%20P%28Stripped%29%20%2A%20P%28Stripped%29)
![Probability = \frac{n(Stripped)}{Total} * \frac{n(Stripped)}{Total}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7Bn%28Stripped%29%7D%7BTotal%7D%20%2A%20%5Cfrac%7Bn%28Stripped%29%7D%7BTotal%7D)
![Probability = \frac{2}{2 + 5 + 3}* \frac{2}{2 + 5 + 3}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B2%7D%7B2%20%2B%205%20%2B%203%7D%2A%20%5Cfrac%7B2%7D%7B2%20%2B%205%20%2B%203%7D)
![Probability = \frac{2}{10}* \frac{2}{10}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B2%7D%7B10%7D%2A%20%5Cfrac%7B2%7D%7B10%7D)
![Probability = \frac{4}{100}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B4%7D%7B100%7D)
![Probability = 0.04](https://tex.z-dn.net/?f=Probability%20%3D%200.04)
