Step-by-step explanation:
The corresponding angle is 75 degrees
Answer:
Step-by-step explanation:
Formula
Sn = (a + a + (n - 1)*d) * n / 2
Givens
Sn = 60
a = 3
Solution
You want integer values for d and n
60 = (2*a + (n - 1)*d) * n/2 Multiply both sides by 2
120 = (2*3 + (n - 1)*d ) * n
120 = (6 + n*d - d) * n
120 = 6n + n^2*d - d*n
This gives some really wild results. I will list all of them here. and then discuss them.
These are the ones that give results without any question and are correct.
n d tn
2 54 3 57
3 17 3 20 37
4 8 3 11 19 27
Here are some that are the gift of the equation
20 0 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3
Now the equation says the following 3 are correct, but are they? Can you have a negative n? The equation says yes, but I doubt your instructor will.
-5 5
-1 63
-2 22
You can bring these up if you are in a classroom. I wouldn't if you have to submit this to a computer which has absolutely no ability whatever to think about exceptions. Even the 20 0 is one I wouldn't use.
Exp.
100 $;
<span> discount of 20% => 80$;
</span> discount of <span>12%</span>% => 80 - 80*(12/100) = 71.4 $;
100 - (x/100)*100 = 71.4 => x = 29.6 => a single discount of 29.6%;
Answer:
Step-by-step explanation:
Hi there!
Open up the parentheses
Combine like terms
Divide both sides by 8 to isolate 
I hope this helps!
This number line is counting by 5's. Each dash is valued 5 numbers.
The blue point would be -10. Even though on this number line -10 visually looks "close" to 10, it isn't. They are 20 numbers apart.
Hope this helped!
