Answer:
d) cannot be determined.
Step-by-step explanation:
x + 60 + a = 180
40 + b + y = 180
Here we cannot find the missing angles because we should know angles to find a missing angle.
Therefore, answer d) cannot be determined.
Hope you will understand the concept.
Thank you.
Answer:
2x-8 = 20-6x
Step-by-step explanation:
The distributive property tells us to multiply the term outside parentheses by everything inside:
2(x-4) = 5(4-2x)+4x
2(x)+2(-4) = 5(4)+5(-2x)+4x
2x-8 = 20-10x+4x
Combining like terms on the right gives us
2x-8 = 20-6x
Answer:
Step-by-step explanation:
Given that,
The value of 
We need to find an expression for 
. To find it, put the value of n as (n-1). So,
Hence, the value of S(n-1) is equal to 
.
My teacher always told me keep change and then opposite
so keep -17
change the minus sign to plus sign
and the opposite is postive 9
*-17+9=-8*
Remember different sign you subtract and keep sign of the biggest number
