Answer:

9z+15

Step-by-step explanation:

-3(-6z-5)-9z

You multiply 3 by the numbers in the *( ) and get

18z+15-9z

Then you add any number with the same variable.

18z with -9z is 9z because different signs means subtract and same signs mean to add.

Then this should be your results.

9z+15

P.S Just in case use GOOGLE or the calculator to double check.

Dudley is biking. He wants to cover 40 miles. If he travels 30 miles every 2 ours, what is the equation of a line that models y,

fgiga [73]

Answer:

y=40-15x

Step-by-step explanation:

Let x represent the number of hours.

We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:

Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.

We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:

, where, y represents number of miles he has left to travel, after biking x hours.
