75% of the students are shorter than 68 inches.
Of the 8 students, only 2 are 68 inches tall or more, meaning theres 1/4 or 25% of students who are taller than 68 inches. That being said, that means there are 3/4 or 75% of students shorter than 68 inches. Thus meaning 75% is your answer.
I hope this helps!
Answer:
see below
Step-by-step explanation:
To find the x intercept set y =0 and solve for x
6x+5y = -30
6x = -30
Divide by 6
x = -30/6 = -5
The x intercept is (-5,0)
To find the y intercept set x =0 and solve for y
6x+5y = -30
5y = -30
Divide by 5
y = -30/5 = -6
The y intercept is (0,-6)
Your answer is, 3/(a -5)
<u>Simplification:</u>
- (a^2 +8a + 15) / (a^2 + 7a + 12) * (3a +12) / (a^2 - 25) =
- (a+3)(a+5)/(a+3)(a+4) * 3(a+4)/(a+5)(a-5) =
Thus, <u>3/(a-5)</u> is your answer.
If Mark starts with 7 tickets, and Hannah gives him 6 more, then Mark has 13 tickets total. The equation for this problem looks like this:
7+6=13.
Mason, on the other hand, has none, because Hannah didn’t give him any, and the question never mentions him buying any.
