The sum of two numbers is 91. the greater number is 7 more than the smaller number. which equation can be used to solve for the smaller number?

a. x(x + 7) = 91
b. x(x − 7) = 91
c. x + (x + 7) = 91
d. x − (x + 7) = 91

sum is addition

7 more than the number would be x+7

so x + (x+7) = 91 is the right formula

Answer is C

it would more likely be bald eagle because its has more in the box so about 75%.

step-by-step explanation:

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.
