Brian was billed for 171 minutes.

Step-by-step explanation:

Given,

Monthly fee of phone = $8

Charges per minute = 6 cents = $0.06

Last month bill of phone = $18.26

Let,

x be the minutes billed.

Therefore,

Monthly fee + 0.06*minutes = Total bill

$8+0.06x=18.26\\0.06x=18.26-8\\0.06x=10.26$

Dividing both sides by 0.06

$\frac{0.06x}{0.06}=\frac{10.26}{0.06}\\x=171$

Brian was billed for 171 minutes.

In one baseball season, Nolan hit twice the difference of the number of home runs Mrs. Davis hit and 6. Altogether, they hit 18

Alborosie

Answer:

Nolan hitted 8 home runs

Step-by-step explanation:

Let's call the number of home runs that Nolan hitted by N, and that Davis hitted by D.

So, we can write the following equations:

N = 2 * (D - 6)

N + D = 18

Now we can solve the system of equations, using the value of N from the first equation in the second one:

2 * (D - 6) + D = 18

2*D - 12 + D = 18

3*D = 30

D = 10

Now we find N:

N + D = 18

N + 10 = 18

N = 8

So we have that Nolan hitted 8 home runs.

“Ms. Blanco drove her car at a speed of 80 kilometers per hour for 1 1/2 hours, then at a speed of 100 kilometers per hour for 2

lara31 [8.8K]

I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250

250+120=370!!

answer : 370 kilometers per hour
