Aphone company charges customers a monthly charge using the equation c = 40 + 0.3m, where is the monthly
charge, in dollars, and m is the number of minutes used by the customer. if someone's monthly charge is $46, how
many minutes did the person use that month?
a. 5
b. 8
c. 10
d. 15
e. 20

Option E

The person used the phone for 20 minutes that month

Solution:

Given that phone company charges customers a monthly charge using the equation:

C = 40 + 0.3m

Where,

"C" is the monthly charge in dollars

"m" is the number of minutes used by the customer

Someone's monthly charge is $46

To find: number of minutes used by that person

Therefore, given C = 46

Substitute C = 46 in given equation

46 = 40 + 0.3m

40 + 0.3m = 46

0.3m = 46 - 40

0.3m = 6

Thus the person used the phone for 20 minutes that month

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
