Answer:
200 minutes ; 3 hours and 20 minutes.
Step-by-step explanation:
If you write a proportion in the form
miles/minutes = miles/minutes
you would get 3/50 = 12/x
from there you cross multiply to get
3x=600, and solve that to get 200 minutes.
another way was to see that 12 is 3*4, and multiply 50 by 4 to get the same answer.
<span>-4(6+n)+3=36
-24 -4n + 3 = 36
-4n -21 = 36
-4n = 36 + 21
-4n = 57
n = -57/4
n = -14.25</span>
Answer:
225
Step-by-step explanation:
The sum of this series is given by the formula:
![S_n=\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Where
S_n is the sum
a is the first term (we get this by plugging in n = 1 into "2n-1", we have 2(1) - 1 = 1)
n is the number of terms (the sum is defined for n = 1 to n = 15, so 15 terms)
d is the common different (the difference is successive terms. Here, 2nd term would be 2(2) - 1 = 3, and first term was 1, so d = 3 -1 = 2)
<em>plugging in the info, we will get the sum:</em>
<em>![S_n=\frac{n}{2}[2a+(n-1)d]\\S_{15}=\frac{15}{2}[2(1)+(15-1)(2)]\\=225](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%5C%5CS_%7B15%7D%3D%5Cfrac%7B15%7D%7B2%7D%5B2%281%29%2B%2815-1%29%282%29%5D%5C%5C%3D225)
</em>
<em>The sum is 225</em>
every similar line means that they have the same value
x=8
y=10
go look for a way to find the last side in the small rectangle that has x and y
