Caitlin had $402 in her bank account. She withdrew $15 each week to pay for a swimming lesson. She now has $237.a. Write an equation that can be used to find the number of swimming lessons that she paid for.
b. How many swimming lessons did she pay for?
c. At the time she has $237, the cost of a lesson rose to $19. How many lessons can she pay for with her remaining $237?

Answers

Answer 1
Answer: a.) Let x be the number of swimming lessons she had, then
402 - 15x = 237

b.) 15x = 402 - 237 = 165
x = 165/15 = 11
She had 11 swimming lessons

c.) Let the number of lesson she had be y, then 19y = 237
y = 237/19 = 12 lessons
She can pay for 12 lessons with her remaining $237.
Answer 2
Answer: A) Equation:

($402 - $237) ÷ $15 = y

B) Solution:

$402 - $236 = $165

$165 ÷ $15 = 11

Answer: 11 Swimming Lessons

C) Equation:

$237 ÷ $19 = 13

Answer: 13 Swimming Lessons

what is the common ratio for the geometric sequence below, written as a faction? 768,480,300,187.5,...

Answers

To determine the common ratio of the geometric sequence, divide the second term with the first term. 480 divided by 768 equals 5/8. Further, the ratio of the third and second terms may be used to check the consistency of the common ratio. The ratio is also 5/8. Thus, the common ratio is 5/8.

Solve the inequality 12x < 22 + x.x < 1/2
x > 1/2
x < 2
x > 2

Answers

The answer is x<2 
I hope i helped!! c;

Answer:

x < 2

Step-by-step explanation:

12x < 22 + x

First, get the constant and variable on separate sides by subtracting x.

12x - x < 22 + x - x

This will result in:

11x < 22

Finally, multiply both sides by 1/11,

this will result in 1 < 2, which should be written as:

x < 2
