A cell phone plan costs $150 to start, Then, thero is a $50 charge each month. What is the total cost, y, for x months? Which equation match this situation Y=150-50x. Y=50x+150. Y=150x+50. -50x+150=y

Y = 50x + 150

Step-by-step explanation:

50 per month (x = unknown number of months) === 50x

$150 is the starting charge (automatic +150)

Y = total cost

Y = 50x + 150

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
