50 students = 7 have red hair

100 students = 14 have red hair

150 students = 21 have red hair

200 students = 28 have red hair

250 students = 35 have red hair

300 students = 42 have red hair

<h2>↓                               ↓</h2>

600 students = 84 have red hair

650 students = 91 have red hair

700 students = 98 have red hair

750 students = 105 have red hair

Therefore, around 105 students would have red hair out of all the students in the school.

What is the solution to the system of equations below?
Anon25 [30]

Answer:

The correct one is A

Step-by-step explanation:

2x-y=10

y=1/2 × x+5

Now you substitute the value of y into the first equation.

2x - (1/2 × x+5) = 10

Solving this equation for x you get that x=6

Now substitute the value of x any of these two equations, doesn't matter. Let's say we do with the first one.

2×6-y=10

12-y=10

-y=10-12

-y= -2

y=2

And so you've got the first one which is, (x,y)=(6,2)

Sam drove 6 1/2 hours on Saturday and 8 2/3 hours on Sunday. How much longer was his drive on Sunday than on Saturday?
Schach [20]
Based on the phrase "how much longer" this is going to be a subtraction problem
8 2/3 - 6 1/2
Steps:
1. Find the least common denominator. Both 3 and 2 have a multiple of 6
2. Multiply 2/3 by 2 (numerator and denominator) and 1/2 by 3 to get an overall denominator of 6
8 4/6 - 6 3/6
3. Now you can do basic subtraction. Subtract the whole numbers
           8-6= 2
 4. subtract the numerators
        4-3=1
Answer is 2 1/6

PLEASE HELP DUE NOW!!!!
Alex Ar [27]

Answer:

4. x=120

5. x=65

9. x=150

10. x=45

Step-by-step explanation:

4. Half=180

There is already a 60, so you do 180-60=120. x=120.

5. This is a parallel line, so you determine the opposite angle of 115, which is 65. That just becomes the x. x=65

9. It is similar to #5, You look at the opposite side of 30 (15+15) which is 150. That just comes to the other side which is x=150.

10. A triangle has 180 degrees in total. 45 degrees is already given, and line j is 90 degrees which means a full line is 180. 180-90=90.

90+45=135

180-135=45

x=45

Hope this helped!
