Answer:

C

Step-by-step explanation:

it is C because 8*60=480 minutes

so 480min/25min=19.20 round=19

25(19)-45=430<480 which is true

Valentin [98]

Answer:

Step-by-step explanation:

Yes, she can use this inequality and it does matter since the number of cars that the inequality provides will need to be equal to or more than that number in order for all the students to be able to go. Therefore, if we apply the inequality it would give us the minimum number of cars needed (n) like so

12  + 3n > 28   ... subtract 12 on both sides  

3n > 16  ... divide both sides by 3

n > 5 1/3

Since there can't be 1/3 of a car and the number of cars needed must be higher than 5 1/3 then we would need a total of 6 cars to take all of the children.

The phone company A Fee and Fee has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount o
IgorLugansk [536]

Answer:

y=0.2x+29

Step-by-step explanation:

Given that:

y is the total monthly of the A Fee and Fee plan.

x is the number of monthly minutes used.

  • If a customer uses 290 minutes, the monthly cost will be $87, we have the pair (290, 87)
  • If the customer uses 980 minutes, the monthly cost will be $225, this is the coordinate pair (980, 225).

We want to obtain an equation in the form: y=mx+b

First, let us determine the slope, m

Given points (290, 87) and (980, 225):

<u>Slope</u>

m=\dfrac{225-87}{980-290} =\dfrac{138}{690}=0.2

Next, we determine the y-intercept, b.

Substituting the pair (290, 87) and m=0.2 in y=mx+b, we obtain

87=0.2(290)+b

b=87-0.2(290)=29

Therefore, our equation in the form y=mx+b is:

y=0.2x+29
