just want to tell you that you can write fractions using / so instead of writing 5 over 6 you can write it 5/6. You probs already knew that but just to make sure you know.
Answer:
Step-by-step explanation:
Remark
A B C have to be multiplied by the same something. No matter what they are multiplied by the sum will be 180 degrees.
Equation
Let the angle ratios be multiplied by x
7x + 8x + 15x = 180
30x = 180
x = 180/30
x = 6
Answer
7*6 = 42
8*6 = 48
15<u>*6 = 90</u>
Total 180 as it should
Answer:
234
Step-by-step explanation:
We want to find the summation from n = 2 to n = 10 of the equation -4 + 5n.
We can use the summation formula:
, where a1 is the first term, is the last term, and n is the number of terms
Here, we can say the first term occurs when n = 2:
-4 + 5n
-4 + 5 * 2 = -4 + 10 = 6
The last term will be when n = 10:
-4 + 5n
-4 + 5 * 10 = -4 + 50 = 46
The number of terms is just 10 - 2 + 1 = 9 terms.
Substitute these in:
Thus, the answer is 234.
The answer is Subtraction property of Equality
