Step-by-step explanation:
well first try by addding the numbers and then dived it by 2
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
Looks like 7 games scored 73 or 74, 1 scored 75 or 76 and 1 scored 77 or 78, so
Answer: 9 games, second choice
Answer:
2
Step-by-step explanation:
Since triangles ABC and ADE are similar by AA (they share angle A and a right angle), their ratio of sides must be equal. Therefore:

Multiply both sides by 2:

Multiply both sides by x+2:

Subtract 2 from both sides:
