Two equal fractions would be 4/6 and 6/9.
−2x + 3y + 5z = −21
−4z = 20
6x − 3y = 0
do -4z=20 first
divide both sides by -4 to get z by itself
-4z/-4=20/-4
z=-5
Use z=-5 into −2x + 3y + 5z = −21
-2x+3y+5(-5)=-21
-2x+3y-25=-21
move -25 to the other side
sign changes from -25 to +25
-2x+3y-25+25=-21+25
-2x+3y=4
6x-3y=0
find x by eliminating y
Add the equations together
-2x+6x+3y+(-3y)=4+0
-2x+6x+3y-3y=4
4x=4
Divide by 4 for both sides
4x/4=4/4
x=1
Use x=1 into 6x − 3y = 0
6(1)-3y=0
6-3y=0
Move 6 to the other side
6-6-3y=0-6
-3y=-6
Divide both sides by -3
-3y/-3=-6/-3
y=2

Step-by-step explanation:
If Point C <em>was </em>located between A & B, then:
However, we are told Point C is <em>not</em>; therefore:
1:3 that's so easy like bruh
Answer: 225 hamburgers were sold on Monday.
Step-by-step explanation:
525 = h + c
h = hamburger
c = cheeseburger
c = 75 + h
h + (h + 75) = 525
2h + 75 = 525
-75
2h = 450
/2
h = 225
