The sum of the page numbers on the facing pages of a book is 69. what are the page numbers.

1 answer:

7 0

Cool problem !
Two pages of a book that face each other are consecutive integers, and one of them is even and the other one is odd.
So let's look at half of 69.
That's 34.5.
So let's try page 34 and page 35.
That works !

Answer:

cscX = $\frac{y}{x}$

Step-by-step explanation:

using the trigonometric identity

cscX = $\frac{1}{sinX}$

sinX = $\frac{opposite}{adjacent}$ = $\frac{x}{y}$

cscX = $\frac{1}{\frac{x}{y} }$ = $\frac{y}{x}$

Ryan starts saving money to buy a car right after his 16th birthday. He already has $120 from his birthday. After 3 months he ha

nlexa [21]

Remark

The basic equation is y = mx + b

y = the total amount of money

m = The amount of money he save each month (it is a constant).

b = the y intercept which is his starting amount or 120 dollars.

x = the number of months (this is a variable).

After 3 months he has 840 dollars. That's y

840 = 3*m + 120 Subtract 120 from both sides

840 - 120 = 3m

720 = 3m

240 = m So he saves 240 every month.

Now the equation becomes.

y = 240 * x + 120

Savings after 24 months

y = Total

m = 240 dollars/month

x = 24 months

b = 120

y = 24*240 + 120

y = 5760 + 120

y = 5580

He had 5580 dollars after saving for 2 years (or 24 months total) This assumes that when he started, he took his birthday money and added a 1 month payment to it
