Evaluate the expression when x=35 and y=6 x / 5 - y

Variable expressions are expressions that involve variables, which are symbols that represent changing quantities. The value of the expression will change as the value of the variable changes.

For example, let's say with have the equation

x

+

5

When

x

=

1

, then

x

+

5

=

6

When

x

=

2

then

x

+

5

=

7

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is
