Answer:
4.50+1.25n=8
Step-by-step explanation:
subtract 4.50 from both sides of the equation which would leave 1.25n=10
then divide 1.25 from 1.25n and 10
n=8
I hope this helps you! i want brainliest sooo bad lol!
14a+35b−21
How to get the answer
<u>Use the distributive property to solve this problem</u>
7*2a=14a
7*5b=35b
7*3=21
<u>Then you add the signs</u>
14a+35b-21
Answer:
![\frac{1+5i}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%2B5i%7D%7B2%7D)
Step-by-step explanation:
We know i×i=i^2 which has value of -1.
We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).
Also multiplying by i/i does not change the value of the fraction because i/i=1.
Numerator × i gives (-5+i)i=-5i+i^2=-5i-1
=-1-5i.
Denominator × i gives (2i)i=2i^2=-2.
So the simplified version of this fraction given is:
![\frac{-1-5i}{-2}=\frac{1+5i}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-1-5i%7D%7B-2%7D%3D%5Cfrac%7B1%2B5i%7D%7B2%7D)
The last simplification come from me multiplying fraction by -1/-1.
