Answer:
y=x/4
Step-by-step explanation:
add x to the other side of your equation so: 4y = x
now divide both sides by 4 so your y is isolated: y=x/4
Answer:
(5, 0)
Step-by-step explanation:
For the first line, we can isolate x by subtracting 5y on both sides.
x=5-5y.
Now we can use substitution on the second line!
-(5-5y)+6y=-5
= -5+5y+6y=-5
=-5+11y=-5
=11y=0
y=0
We subsitute y for the first line,
x+5(0)=5
x+0=5
x=5
We can check our work by plugging in x and y
5+5(0)=5 ✔
-5+6(0)=-5 ✔
.50 x 15 = 7.5. This is the total amount of miles he was charged.
7.5 + 3.00 (the base charged) = 10.50
Answer:
a. 6 commercials.
b. 12 commercials.
Step-by-step explanation:
a. You know that the entire commercial break is 3.6 minutes.
Then, if each commercial takes 0.6 minutes, you need to divide 3.6 minutes by 0.6 minutes in order to calculate the number of commercials that will be played.
Therefore, you get:
b. The other commercial break has the same lenght that the other one (3.6 minutes), but the commercials are half as long; this means that each commercial takes 0.3 minutes.
Then, you need to divide 3.6 minutes by 0.3 minutes in order to calculate the number of commercials that will be played during this break:
8/0 = undefined
Reason: You cannot have 8 parts of nothing, and so it is not possible.
hope this helps
