PQ peependicular to PS
Thus angle QPS = 90⁰
7x - 9 + 4x + 22 = 90⁰
11x = 77
x = 7
Thus angle QPR = 7(7) - 9 = 40⁰
It is not as tough a problem as it seems to you. You can easily grasp the problem, once it is done,
9 5/9 - 6 5/6 = 86/9 - 41/6
= (172 - 123)/18
= 49/18
= 2 13/18
I hope that the simplification process is simple enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
The square root of 20 is an irrational number because you cannot turn it into a fraction.
The number on the screenshot is the square root of 20. Because this number doesn't end or repeat, you can't make it a fraction, and therefore it's irrational.
{ 5 x - y = 20
2 x + y = 15
_____________
7 x = 35
x = 35 / 7
x = 5
For y :
2 x + y = 15
2*(5) + y = 15
10 + y = 15
y = 15 - 10
y = 5
Answer A ( 5,5 )
hope this helps!
Answer:
c / 2x²=32
Step-by-step explanation:
so we have 2x²=32
x²=32/2
x²=16
x=√16 and x= -√16
x=4 and x= -4
