nick and steph are each saving money to buy a bus ticket The total cost foe two tickets is $390 Steph current has $75 in her bank account and plans to savw $15 each week whick equation could she use to calculate the number of week (x) it will take her to save enough money to buy her ticket

it will take 8 weeks

8 x 15 =120

120+75= 195

195x2= 390

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer is 489
