Answer:
1st → 1st
2nd → 3rd
3rd → 2nd
Step-by-step explanation:
just divide the first set of student wishes to the second set of students in the same question. the 1st for example
x-ray to all students is 6/ 36= 1/6 = 1:6
for all students, you add all the students in the table
First take out the GCF which is 4x
4x (x^2 - 3x - 10) = 0
4x(x - 5)(x + 2) = 0
4x = 0 so x = 0
x - 5 = 0 so x = 5
x+2 = 0 so x = -2
zeros are -2, 0 and 5
Answer:
(4, 3)
Step-by-step explanation:
x = (-2 + 10)/2 = 4
y = (3+3)/2 = 3
(4,3)
Variables:
cost of 1 hot dog = x
cost of 1 hamburger = y
Set up a system of equations and use substitution
x + y = 2.75
x + 7y = 11.75
x + y = 2.75 can be rewritten as y = -x + 2.75
x + 7 (-x + 2.75) = 11.25
-6x + 19.25 = 11.25
-6x = -8
x = .75
plug x back into other equation to find y
y = -.75 + 2.75
y = 2.00
1 hot dog = $0.75
1 hamburger = $2.00
It would be a variable minus 6 so for example n-6
