Delia and beto left for school at the same time.
delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile. beto lives 3 1/2 miles from school
and bikes at a pace of 3 minutes per mile. who will get to
school first?

Beto will reach school first

Step-by-step explanation:

Delia lives 3/4 mile from school, and if she walks at 16 minutes per mile, it would take her

3/4 x 16 = 12 minutes to reach school.

Beto lives 3 1/2 (7/2) miles from school, and if she walks 3 minutes a mile, it would take her

7/2 x 3 = 10.5 minutes to reach school

Beto reaches school first

Step-by-step explanation:

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes 12 minutes to reach school.

While Beto lives 3 1/2 miles from school  and bikes at a pace of 3 minutes per mile.

So Beto takes 10.5 minutes to reach school.

Therefore, Beto reaches school first.

x+14

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
