Answer:
supplementary angles
Step-by-step explanation:
If s represents the number of students, then the number of pizzas is
s/4 + 2 = 9
s/4 = 7 . . . . . . subtract 2
s = 28 . . . . . . multiply by 4
There are 28 students.
Answer:
The second equation can be written by equation (1) is given below
8x-5y=3
The two equations represents the same line and therefore they have an infinite number of solutions that are true for both equations.
Step-by-step explanation:
Given equation is 
To find the second equation to create the given system of equations to have infinitely many solutions :
The second equation can be written by equation (1) is given below
8x-5y=3
The two equations represents the same line and therefore they have an infinite number of solutions that are true for both equations.
Answer:
4.2 is: 1.) between 4 and 5 closer to 4
7/8 is: 3.) between 0 and 1 closer to 1
-9/5 is: 2.) between -1 and -2, closer to -2
21 = 3(3n - 5)
21 = 3(3n) - 3(5)
21 = 9n - 15
<u>+15 +15</u>
<u>36 </u>= <u>9n</u>
9 9
4 = n
