Answer:
If un= 3n+2, find u, and u Show that u n+1-Un= 3. 2. (i) If un=n2-3, find u , u ... If un= 3 + n(n-1), show that unti-un= 3n2-n. ... Sn=[a+(n-1)d] + [a + (n - 2)d] +.
Step-by-step explanation:
The correct answer should be 36% or 9/25. Hope this helps!
Answer:
Step-by-step explanation:
we will use distributive property to write an equivalent expression:
7(-2x)+7(6)
First solve for the other angles.
You know one angle is 15º.
The one across from it is also 15º since it is a vertical angle to the known 15º angle.
Both of those together gets 30º.
The whole thing is 360º, so just subtract 30 from 360 and divide.
360 - 30 = 330
Do the same for the 15x angle.
The one under/across to it is a vertical angle so is also 15xº.
Now you are left with 30xº = 330.
Just divide now.
330 / 30 = 11
x = 11
15x = 165
Checking your work:
15x = 165
15x = 165
15
15
Those are the angles.
Add those numbers together and make sure it adds up to 360º.
165 + 165 + 15 + 15 = 360
So this is correct.
Answer:
Let's solve the expression!
Step-by-step explanation:
Your answer is 75.
The fraction shows 150 ÷ 2 and 2x ÷ 2.
I hope this helps!
