Use the Law of Sines to solve for x. Round to the nearest whole number.
bagirrra123 [75]

Answer:

12.94

Step-by-step explanation:

By the law of sines:

x / sin(35) = 7.9 / sin70

x = 7.9 * sin(70)/sin(35)

Sam is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month
vodomira [7]

Answer:

13 months

Step-by-step explanation:

x is the number of months

first phone:

f(x) = 55x + 100

second phone:

g(x) = 51x + 150

now set up the inequality

g(x)<f(x)

51x + 150 < 55x + 100

Solve the inequality: 

51x + 150 < 55x + 100

(get everything on the correct sides... combine the like terms)

51x - 55x < 100 - 150

-4x < -50

divide both sides by -4 (don't forget to flip the inequality sign when dividing by a negative number.)

x > 50/4

x > 12.5

round up to 13
