Answer: it will take 25 months
Step-by-step explanation:
Let x represent the number of months that it will take for the cost of both plans to be the same.
Cell phone Plan A costs $70 per month and comes with a free $500 phone. This means that the total cost of x months with plan A would be
70 × x = $70x
Cell phone plan B costs 50 per month but does not come with a phone. If you buy the 500 phone and choose plan B, then the total cost of x months with plan B would be
500 + 50 × x = 500 + 50x
To determine the number of months until your cost is the same as Plan A's, we would equate both costs. It becomes
70x = 500 + 50x
70x - 50x = 500
20x = 500
x = 500/20 =25
the correct answer is y=2
Answer:
r = 18 cm
Step-by-step explanation:
Hello
The formula for circumference is 2*Pi*r
So you have the valur for that formula:
2*Pi*r = 36Pi
r = 36/2
r = 18 cm
Bes regards
Ax+by=c
a=(-by+c)/x
b=(-ax+c)/x
c=ax+by
x=(-by+c)/a
y=(-ax+c)/b. or y= -a/b x + c/b which is slope intercept form
Answer:

Step-by-step explanation:
Let
equal the weight of the baby.
If we know the baby weighs <em>more </em>than
