Answer:
The answer is B.
Step-by-step explanation:
Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :




1. x=-5
2. x=10
3. x=4
4. x=5
5. x=8
6.x=10
29 , 35 , 41
the sequence is going up
in 6s
Answer:
-
Step-by-step explanation:
-x= -1x. (The 1 is invisible)
Now lets do the 3*-1= -3
You still have both of the x's.
All you do is add them. 1+1=2
So, your exponent is going to be 2 with x attached
***When you are multiplying and you have the same exponent, add them. Pretend that you see the exponent 1 by the x (
) now since you have 2 (
) which equals (
)
Looks Like:
3x* -x
=3x* -(1)x
= 
Hope this helped :)
10 - 6x = 160 - 10x
+6x +6x
-10 + 6 = -4
10 = 160 - 4x
-160
10 - 160 = -150
-4x = -150
-4x/4 = -150/-4
x= 37.5
