Sponsors:

5s + 10 = 200

You need to get rid of 10 first, you do this by subtracting it by 10, you also subtract 10 to 200

5s = 190

Now you need to get rid of 5 that is attached to the variable, you must divide 5 since it is multiplying, also dividing 5 to 190

s = 38

So it would be 38 sponsors



Comic books:

4c + 6 ≤ 20

Take away 6 by subtracting, also subtracting 6 to 20

4c ≤ 14

You then have to divide 4 to the variable, also dividing 4 to 14

c ≤ 3.5

Now since you can’t get half of a comic book, the greatest amount of comic books he can buy is 3.

3 comic books



Value of x:

3x + 1 = 10

Take away 1 by subtracting 1, also subtracting 1 to 10

3x = 9

Divide 3 to the variable, dividing 3 to 9 as well

x = 3



Value of y:

4y + 6 ≥ 18

Subtract 6 to 6 and 18

4y ≥ 12

Divide 4 to both sides

y ≥ 3 or y is greater than or equal to 3 (in case you can’t see the symbol)

Hope this helps! :)

3. Three soccer players are scored 25 goals this season.
Varvara68 [4.7K]

The mean goals scored by the soccer players this season is 18.3 goals

<h3>What is mean? </h3>

Mean is the ratio of the sum of data to the total sample of data.

If three soccer players are scored 25 goals this season., five soccer players  scored 19 goals this season and ten soccer players scored 16 goals this season, the mean goal scored is expressed as:

Mean goal scored = 3(25)+5(19)+10(16)/3+5+10

Mean goal scored = 75 + 95+160/18

Mean goal scored = 330/18

  • Mean goal scored = 18.3 goals

Hence the mean goals scored by the soccer players this season is 18.3 goals
