Hello!

your answer is: B.  n + 25 = 61

If megan had 25 numbers, and both Megan's and Abby's total numbers add up to 61, then n is the amount of numbers you need to add to 25 to get 61.

n + 25 = 61

36 + 25 = 61

therefore n = 36

I hope this helps, and have a nice day!

Alfred collects black and brown socks but loses a lot of them. If 60% of all his socks are brown, 20% of his brown socks are in

Ipatiy [6.2K]

Answer:

Alfred has 250 socks in his collection.

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Based on the information given to us we can see that out of All his Brown socks he has 20% in the wash and the rest are in his drawer. Meaning 80% of the Brown socks are in his drawer. So we first need to find how many Brown socks are in the wash. We can solve this using the Rule of Three property as shown in the picture below.

120 drawer ⇒ 80%

x wash ⇒ 20%

$\frac{120*20}{80} = 30$

Now that we have the amount of Brown socks in the washer we can add that to the amount in the drawer to find the total amount of Brown socks.

$Br = 120+30\\Br = 150$

So we now know that there are a total of 150 Brown socks. Since the question states that the Brown socks are 60% of the total we can use the Rule of Three to find the total.

150 Brown ⇒ 60%

T Total ⇒ 100%

$\frac{150*100}{60} = T$

$250 socks = T$

Finally, we can see that Alfred has 250 socks in his collection.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

fiasKO [112]

<h3>Answer: 7/19</h3>

Explanation:

There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total

The probability of selecting blue is therefore 7/19

We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.

Gnesinka [82]

Answer:

AC = 127,26 f distance from home plate to second base

Step-by-step explanation:

Let call A , B , C Home plate, first base and second base respectively

These three point form a right triangle with legs ( AB = BC = 90 feet)

we have an isosceles triangle with a right angle and two angles of 45⁰

So we need to compute distance AC (hypotenuse)

AC² = AB² + BC² ⇒ AC² = 2AB² ⇒ AC = AB √2

AC = 90 * 1,414

AC = 127,26 f
