distribute the 3
3x-12 = 12x
subtract 3x from both sides
-12 = 9x
divide both sides by 9
-12/9 = x
simplify
-4/3 = x

3. Find m∠Q
4. Find m∠1
5. Find m∠3
Answers
Answer:
3) (N) angle Q = 90 degrees
4) (E) angle 1 = 88 degrees
5) (G) angle 3 = 110 degrees
Step-by-step explanation:
3) angle Q = 1/2(270-90) = 90
4) central angles equal arc angles
5) angle supplemental to angle 3 is 1/2(140), so angle 3 = 180-70 = 110

What is the value of x?
Thanks
Answers
Answer:
x = 6√3
Step-by-step explanation:
Let's just look at the right triangle. This is a 30° 60° 90° triangle. The value of the large leg (x) will be the value of the small leg times √3. The value of the hypotenuse (12) is the value of the small leg times 2. Since we know that, we can divide 12 by 2 to find out the value of the small leg will be 6. Finally, know that we know that 6 is the value of the small leg, we can multiply 6 by √3 to find that the value of x = 6√3.
Answer: [tex]6\sqrt{3}[/tex]
Step-by-step explanation:
This is a 30-60-90 triangle because we know that there is a right angle and a 60 degree angle
the side opposite to 30 degrees is a, 90 degrees is 2a, and the side opposite to 30 degrees is [tex]a\sqrt{3}[/tex]
2a = 12 so a = 6 and [tex]a\sqrt{3}[/tex] is [tex]6\sqrt{3}[/tex]
What values of x is log (2x-5) valid
Answers
Answer:
To solve this you must first know how Log works.
When we say log1000 of base 10
Or
log1000=3
What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).
So log2x=−5 (i am assuming base 10 since it is simple algebra) means that
2x=10−5
x=10−5/2
Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.
The question is not written properly, so I will give the answer(s) I think would be suitable.
If you were trying to solve this
log2x=−5
⟹x=2−5
⟹x=132
But if you were trying to solve this
log2x=−5
⟹log102x=−5
⟹2x=10−5
⟹x=12×105=1200000

The population P, in millions, of a certain country can be modeled by the function P(t) = 3.98(1.02)t, where t is the number of years after 1990.
Answers
Answer:
7.35 Million
Step-by-step explanation:
So you already have the function and all you have to do is find the years.
p(t)=3.98(1.02)^t
I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.
p(t)=3.98(1.02)^31
From here you would jut plug this function into your calculator and get a final answer of:
7.35 Million

The original price p of an item less a discount of 60%
Answers
Answer:
p - p(.60)
Step-by-step explanation:
to find 60% of p you turn 60% into a decimal, which is .60, next you multiply .60 by p which will give you 60% off of p,
finally you take the total which is p and subtract off the discount which is .60p, thus p-p(.60)
also... another way to solve this is that if you are getting 60% off that means you are paying 40% of the price, thus you could just multiply p(.40) to get the amount the person would actually pay
