Basically, ur just solving for y
6x + 4y = 8...subtract 6x from both sides
4y = -6x + 8....now divide both sides by 4
y = (-6/4)x + 8/4...reduce
y = -3/2x + 2 <=== slope intercept form
As likely as not.
EXPLANATION: a coin has 2 sides. (usually heads and tails)
50% chance it is heads
50% chance it is tails
50=50.
So it is just as likely to happen as it is likely to not.
= (3/4 + 1/3)/(1/6 + 3/4)
= (3/4 + 1/3)/(1/6 + 3/4)
Multiply numerator and denoiminator by 12
=12(3/4+1/3) / 12(1/6 + 3/4)
= (3*3 + 1*4) / (2 + 3*3)
= 13/11
Namely, how much is 2 and 1/2 of 2 and 3/8 then, well is just their product, let's first convert them both from mixed to "improper" and proceed.
Answer:
C = 250S + 4500
17 tons = $8750
simply plug in 17 into the variable S and solve for C to find the total cost
