Answer:
1. coefficient
2. variable
3. constant
Step-by-step explanation:
X = pencils, y = pens
8x + 6y = 8.50
4x + 4y = 5.....multiply by -2
----------------
8x + 6y = 8.50
-8x - 8y = -10 (result of multiplying by -2)
-----------------add
-2y = - 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75
4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50
Y= 1/2x -2 is the equation for this line.
Answer:
m>2 is the correct answer
Answer:
110 pages
Step-by-step explanation:
The rate of 55 pg in 30 minutes is given in "minutes".
Thus,
we need to convert 1 hour to minutes.
We know 1 hour = 60 minutes
Note: 30 mins * 2 = 60 minutes
Logically, 30 minutes makes 55 pages, so 60 minutes (30 * 2) will make 55 * 2 = 110 pages
So, in 1 hour, it can print 110 pages (at this rate)
