Greetings.
The answer is (5,4)
Explanation:
Solving by elimination can be done by adding or subtracting of first and two equation.
Find any terms that make themselves = 0.
And that is the y-term.
Our 2y and -2y. If we add each others, we'd get 0 for y-term.
Therefore, we eliminate the y-term first.

If you are wondering how I get 2x = 10 then here's the explanation.
So we simply add/subtract both equations.
We do -x + 3x = 2x
Then +2y - 2y = 0
And 3 + 7 = 10
That's how we get 2x = 10.
Basically Add/Subtract in Vertical way.

We may get the x-value but we need to know the y-value too.
Therefore, substitute x = 5 into any given equations. I suggest you to substitute the x-value in any equations with less coefficient value.
I'd rather substitute x = 5 in -x+2y = 3.

Substitute x = 5 in -x + 2y = 3

Therefore, when x = 5, y = 4. Since you want the answer in ordered pairs then It's (5,4).
The turtle population will be 486 after 5 years.
<u>Step-by-step explanation</u>:
The general form of a geometric progression or geometric sequence is a, ar, ar², ar³ and so on.
where,
- a = first term
- r = common ratio
<u>The formula to find the nth term in GP is :</u>
nth term = 
The given sequence 6,18,54.
In this sequence,
- The first term, a = 6
- The common ratio, r = 18/6 = 3
5th term = 
⇒ 
⇒ 6
81
⇒ 486
Therefore, after 5 years the population will be 486.
Answer:
3.8
Step-by-step explanation:
so if he walked 4.5 miles -2.4 miles for closer to his house + 1.7 miles further
4.5-2.4+1.7=3.8
Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.
So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.
1/4 * 2/1= 2/4 = 1/2
Yes, we can see each triangle has congruent angle, side, angle, respectively (SAD). When two triangles have these correlating congruences, they can be determined as congruent.
