Which is it
2x times y times 3 = 6xy
or,
2xxyx3= 6x^3y
Let "x" be a substitute for "a number"
1/3(x)=x-12 Multiply by 3
x=3x-36 Get n onto the same side of the equation
2x=36 Divide by 2
x=18
That's your answer.
Answer:
y=-3x+3/2
Step-by-step explanation:
move 6x to the other side
2y=-6x+3
then divide y
y=-3x+3/2
Propane costs $3.50 per hundred pounds,
and there is a $6 monthly delivery fee.
A family has budgeted $85 for their propane this month.
Let 'x' hundreds of pounds can the family use without going over budget
Here family has budgeted $85 for their propane.
So the cost for Propane = $ 3.5x
One month delivery fee $6
Therefore cost + delivery charge not exceed $85
So 3.5x + 6 ≤ 85
3.5x=85-6 =79
x = 22.57
Therefore 22 hundreds of pounds can the family use without going over budget
