Answer:
Step-by-step explanation:
(5y - 2.3) + (-2y - 4.3) = 3y - n Remove the brackets
5y - 2.3 - 2y - 4.3 = 3y - n Combine like terms
3y - 6.6 = 3y - n Subtract 3y from both sidess
- 6.6 = - n Divide by - 1
6.6 = n

Im supposed to find angles for these, and I don't know on how to do that
Answer:
110
Step-by-step explanation:
They are equal to each other.
23x-5= 21x +5
2x = 10
x = 5
21(5) +5 = 110°
23(5) -5 = 110°
So it works. Angles are 110°

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.
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
Hope this helped :)

Step-by-step explanation:
5×4^(x+1)-16^x=64
0=64+16^x-5×4¹×4^x
0=(4^x)²-2×4^x×10+10²-10²+64
0=(4^x-10)²-36
(4^x-10)²=36
4^x-10=√36
4^x=+-6+10
when positive
4^x=4²
:.x=2
when negative
4^x=4
:.x=1
:.x=1,2 answer.
Find the value of the expression 3m2 + 2p2 − 15 when m = 3 and p = 10
Answer:
43
Step-by-step explanation:
you plug in the values
3m^2 + 2p^2 - 15
= 3(3)^2+2(10)^2-15
= 3×9+2×100-15
= 27+200-15
= 227-15
= 212
Just subtitute the value of m and p to the equation

5. Find m∠3
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

The original price p of an item less a discount of 60%
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

Problem 3
Answer: x = 47Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.
==================================================
Problem 4
Answer: x = 32Explanation:
Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.
For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74
Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32
==================================================
Problem 5
Answer: x = 58Explanation:
Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.
For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58
Answer:
3. x = 47
4. x = 32
5. x = 58
