Three more than the product of a number and 9 is equal to 8

The number is 5/9

Step-by-step explanation:

Let

x ---> the number

we know that

The number multiplied by 9 plus 3 must be equal to 8

so

The linear equation that represent this problem is

solve for x

subtract 3 both sides

Divide by 9 both sides

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
