Y=10°
If we're solving for the ninety degree angle, which I seem to doubt, then if 3x=90 then 2x=60 giving a missing total of 30. 30/3 equals 10
Answer:
25150
Step-by-step explanation:
First, we have to see that this is an arithmetic sequence... since to get the next element we add 5 to it. (a geometric sequence would be a multiplication, not an addition)
So, we have a, the first term (a = 4), and we have the difference between each term (d = 5), and we want to find the SUM of the first 100 terms.
To do this without spending hours writing them down, we can use this formula:
If we plug in our values, we have:
S = 50 * (8 + 495) = 50 * 503 = 25150
Answer:
Step-by-step explanation:
Since have the same denominators, we add them first. We then add to the result.
Answer:
Step-by-step explanation:
Having the following equation given in the exercise:
You can solve for "a" following this procedure:
1. You can apply the Subtraction property of equality and subtract from both sides of the equation:
2. Now you must subtract the terms on the left side of the equation. Notice that the Least Common Denominator is "d". Then:
3. Finally, you can apply the Multiplication property of equality and multiply both sides of the equation by "b". So, you get:
<span>oh i get it well to make two equations equal you have to find something that fits in x. you see the eqal sign? that is seperating the two equations that you have to make equal </span>
