One number is 4 more than another, and their sum is 60. what is the smaller number? if x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?
a. x+y=60 and -x+y=4
b. x+y=60 and x-y=4
c. x+y=60 and x+y=4

a. and

Step-by-step explanation:

Let x be the larger number and y be the smaller number.

We have been given that one number is 4 more than another. We can represent this information in an equation as:

We can manipulate this equation as:

We are also told that the sum of both numbers is 60. We can represent this information in an equation as:

Upon looking at our given choices, we can see that option 'a' is the correct choice.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

i would say b) is your answer

sorry if im wrong
