Answer:
an independant variable dosent depend on any thing and a dependant variable depends on
if you rode a paddle boat for 30 min it cost 10 dollars
the 30 min is the independant variable and the 10 dollars is the dependant variable bc if u wanted to ride for longer than 30min you will have to pay more money therefore the cost depends on the time and time is independent bc the dosent depend on anything
Answer:
x=0, y=2
Step-by-step explanation:
Please see attached picture for full solution.
First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4
Let's assume two variables x and y which represent the local and international calls respectively.
x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84
51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1)
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes
