I am thinking of a positive integer that is 3 less than 3 times another number. The product of my number and the other number is 90. a. Write an equation to represent this situation.
b. What is my number?

This is so hard and it’s for a test

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6
