4÷(6-(8÷2))=2
Do the order of operations, and the end value will be 2.
Do you understand how I got that? Good luck by the way!
Answer:
x=4
Step-by-step explanation:
4x=8x-16
(plus both sides by 16 and minus both sides by 4x)
16=4x
(divide 16 by 4 )
x=4
You multiply everything in the parenthesis by the number outside.
In this case its 2 and -1. the first part is 2a-8 the second part is 4a -2a+16a
so it looks like this 2a-8=4a-2a+16a.
combine like terms and get 2a-8=18a.
Subtract the other 2a from the other side and you have 8=16a
divide each side by 16 and you have 8/16 which is one half.
Answer:
75
Step-by-step explanation:
Given:
mAB =105
The minor arc given mAB is 105. Subtract that from 360 to get the measure of the major arc mACB
<=> mACB = 360 - 105 = 255
As we know, the measure of an angle formed by two tangents intersesting outside the circle can be found by one haft of the difference between the mearsure of two intercepted arcs
=> the measure of ∠P is:
= (mACB - mAB)/ 2
= (255 - 105)/2
= 75
