He sum of two numbers is 47. the greater number is 9 more than the smaller number. which equation can be used to solve for the smaller number? (5 points) x(x + 9) = 47 x + (x + 9) = 47 x(x − 9) = 47 x − (x + 9) = 47

x + ( x + 9 ) = 47

Step-by-step explanation:

b) 36

step-by-step explanation:

18 times 2 is 36

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
