Answer:
b
Step-by-step explanation:
3.25+.3=3.55
<h2>1.</h2>
Firstly, combine like terms: 
Next, subtract r on both sides of the equation: 
Next, add 8 onto both sides of the equation: 
Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>
<h2>2.</h2>
Firstly, multiply both sides by e: 
Lastly, divide both sides by 3, and <em><u>your answer will be 
</u></em>
I would say the answer is 8.25
Answer:
True
Step-by-step explanation:
We knwo this is true because a triangle angle theorem is that the sum of the angles in a triangle is equal to 180 degrees.
Since tri = 3 then,
=> 180/3 = 60
Equal = same --> def. of equilateral triangle
Thus, we know it is true that in an equilateral triangle, each angle is 60 degrees
Hope this helps!
Using elimination method to find y
3x - 4y = -15 (multiply 4)
4x + 3y = 5 (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y = 15
--------------------- - (substract)
-25y = -75
y = 3
Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1
The solution (-1,3)
