Answer:
2400 pages
Step-by-step explanation:
Printer 1 : 50+ 1.50/30 x where x is the number of pages
Printer 2 : 10 + 2/30 x where x is the number of pages
Set them equal
50+ 1.50/30 x = 10 + 2/30 x
50 + 1/20x = 10 +1/15 x
Subtract 1/20x from each side
50 + 1/20x -1/20x= 10 +1/15 x-1/20x
50 = 10 +1/15x - 1/20x
Subtract 10 from each side
40 = 1/15x - 1/20x
Get a common denominator
40 = 4/60x - 3/60x
40 =1/60x
Multiply by 60
40 *60 = 1/60x *60
2400 =x
#Monday memories
can be one, as Throwback Thursday means that it was from a long time ago

Answer:
(0,-3)
Step-by-step explanation:
2x-y = 3
x+2y = -6
Multiply the first equation by 2 so we can eliminate y
2(2x-y =3)
4x -2y = 6
Add this to the second equation
4x -2y = 6
x+2y = -6
-----------------
5x +0y = 0
x = 0
Now find t
x+2y = -6
0+2y = -6
2y =-6
Divide by 2
y = -3
Answer:
The correct one is the bottom choice.
Step-by-step explanation:
This is because the proportion is saying that side BC over side YZ is the same as 28 over 14. This is correct because 28 and 14 are the actual lengths of these sides of the triangle. The other choices do not relate to the same sides of both triangles.
<span>Simplifying
0x + 7 + 5x = 2x + 30 + 40
Anything times zero is zero.
0x + 7 + 5x = 2x + 30 + 40
Combine like terms: 0 + 7 = 7
7 + 5x = 2x + 30 + 40
Reorder the terms:
7 + 5x = 30 + 40 + 2x
Combine like terms: 30 + 40 = 70
7 + 5x = 70 + 2x
Solving
7 + 5x = 70 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
7 + 5x + -2x = 70 + 2x + -2x
Combine like terms: 5x + -2x = 3x
7 + 3x = 70 + 2x + -2x
Combine like terms: 2x + -2x = 0
7 + 3x = 70 + 0
7 + 3x = 70
Add '-7' to each side of the equation.
7 + -7 + 3x = 70 + -7
Combine like terms: 7 + -7 = 0
0 + 3x = 70 + -7
3x = 70 + -7
Combine like terms: 70 + -7 = 63
3x = 63
Divide each side by '3'.
x = 21
