There are 350 students who play sports at school. 1/7 of them play indoor sports. The rest of the students play out-door How many students play indoor and
outdoor sports

50 students play indoors

300 students play outdoors

Step-by-step explanation:

Divide the total number of students by 7 to find the number of them who play indoor.

350 / 7 = 50

Multiply 50 by 6 since 50 is just 1/7 and 6/7 is just multiplying that value by 6.

50 * 6 = 300

Best of Luck!

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the answer to the question is a  

it has the same slope and the same y-intercept.
