Answer: 12 children

Step-by-step explanation:

If 60% can swim, then that means 40% do not swim.

40% = 4/10 = 2/5

2/5 * 30 children = 12 children.

Answer:

12 children cannot swim

Step-by-step explanation:

100% - 60% = 40%

40% cannot swim.

40% can become 0.4.

30 children * 0.4 = 12 children cannot swim

Find the slope and the y-intercept of the equation y − 3(x − 1) = 0.

djyliett [7]

Y-(3x-1)=0
y-3x+1=0
y=3x-1
The equation is in the form y=mx+q where m is the slope and q is the y-intercept.
Then the slope of that line is 3 and y-intercept is -1
