Answer:

The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.

215 of a mile, in 20 minutes, how much in 60 minutes?#

They will pave 3 times more.

215×31=615 of a mile

615=25 of a mile

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.

Look at what happens:

215÷20×60

=215×120×603

=215×3 ← exactly the same maths.

=25

A countertop is 16 feet long and 3 feet wide. what is the area of the countertop in square meters

Paladinen [302]

The area of the countertop is (16-ft x 3-ft) = 48 feet² .

1 foot = 0.3048 meter (rounded)

(1 foot)² = (0.3048 meter)² = 0.0929 meter²

48 feet² = (48 x 0.0929) = 4.459 meter² (rounded)

Travka [436]

Given:

Nancy is running 3 meters per second.

Juan starts the same race 3 meters ahead of Nancy but he is going at 2 meters per second.

To find:

The equations for Nancy and Juan.

Solution:

Let x be the number of seconds.

Nancy is running 3 meters per second. So, the total distance covered by Nancy in the race is

$y=3x$

Juan starts the same race 3 meters ahead of Nancy but he is going at 2 meters per second. So, the total distance covered by Juan in the race is

$y=3+2x$

Therefore, the equations of Nancy and Juan are $y=3x$ and $y=3+2x$ respectively.

Can someone please help me with number 6 complete the statement the state the property illustrated by the statement

djyliett [7]

Answer:

Eliminate redundant parentheses

( − 5 ) = 1 − 5 = 1

Divide both sides of the equation by the same term− 5 = 1

-5x/-5 = 1/-5

Simplify

Cancel terms that are in both the numerator and denominator

-5x/-5=1/-5 x=1/-5

Divide the numbers

x=-1/5

Step-by-step explanation:

ANSWER x=-1/5
