Students in a class were asked to name their favorite sport they like to watch on television. How many more time students want to watch basketball over students who want to watch soccer? Basketball 25.5%Soccer .03%

Answers

First, we need to add up all the percentages to make sure we have 100%.

25.5% + 0.03% = 25.53%

This means that 74.47% of the students chose something other than basketball or soccer.

The amount of students you stated there were was 2553.

25.5% of 2553 is 651 students and

0.03% is 8 students.

Now, we divide 651 by 8 to determine the amount of times over basketball was chosen.

651 ÷ 8 = 81

Basketball was chosen 81 times over again compared to soccer.

To find how much more times basketball was chosen, subtract 8 from 651

651 - 8 = 643

Basketball was chosen 643 times more than soccer.

Answer:

Step-by-step explanation:

Which statement describes the solution to the equation a+5(2a−1)+3=11a−2 ?A.The equation has no solution.

b. The equation has exactly one solution, a=2 11 .

C. The equation has exactly one solution, a=−4 .

D. The equation has infinitely many solutions.

Answers

a+5(2a-1)+3=11a-2
First thing to do is distribute
5*2a=10a
5*-1=-5
a+10a-5=11a-2
Add the similar numbers together
11a-5=11a-2
Then subtract
11a-11a
-5=-2
This equation has no solutions
If it had infinity solutions then both numbers on each side would equal the same, ex: -5=-5

1st distribute

a + 10a - 5 + 3 = 11a -2

Then combine like terms

11a-2 = 11a-2

0=0

Infinite solutions
