Answer:
300 students
Step-by-step explanation:
If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.
195/65= 3
So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.
If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.
3x100=300
We can check this by finding 65% of 300, and seeing if that is 195.
300x.65=195
It does check out.
Answer:
the first system
Step-by-step explanation:
if you put each equation into slope-intercept form you get:
y ≤ -3/5x + 2
y < x - 5
y < -5x + 6
if you place all three equations into a graphing calculator the result will look identical to the graph

Answer:
4 1/6 miles per hour
Step-by-step explanation:
6 minutes is 1/10 hour, so Sara's speed is ...
speed = distance/time
speed = (5/12 mi)/(1/10 h) = 50/12 mi/h
speed = 4 1/6 mi/h
Sara's speed is 4 1/6 miles per hour.
7.00 times 12 is $84. 7.00 is taken out each month and there are 12 months in a year.
