There are 5280 feet in a mile. how many feet are in 7/11 of a mile

pychu [463]

Number of feet in a mile multiplied by the percentage (7/11) equals number of feet in the 7/11 portion of a mile.

=5280 * 7/11
=(5280*7)/11
=36,960/11
=3,360 feet in 7/11 mile

Hope this helps! :)

Aaron's car used 3- gallons of gas when

We want to find miles per gallon. Another way of saying miles per gallon is miles/gallon. So we will plug the numbers into this equation:

60 miles/3 gallons = 20 miles/gallon

This is because 60/3=20.

I hope this makes sense.

The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is th

Dafna11 [192]

Answer:

$a + b \geq 30$

$b - a \geq 10$

Step-by-step explanation:

Given

The sum of the two positive integer a and b is at least 30, this means the sum of the two positive integer is 30 or greater than 30, so we write the inequalities as below.

$a + b \geq 30$

The difference of the two integers is at least 10, if b is the greater integer then we subtract integer a from integer b, so we write the inequality as below.

$b - a \geq 10$

Therefore, the following system of inequalities could represent the values of two positive integers a and b.

$a + b \geq 30$

$b - a \geq 10$
