The largest telescope in the world is powerful enough to identify a penny that is 5 miles away. How many yards is this?

mojhsa [17]

We are given

The largest telescope in the world is powerful enough to identify a penny that is 5 miles away

it means that

distance =5 miles

we can change it into yards

we know that

1 mile=1760 yards

$d=5\times 1mile$

we can replace 1 mile

$d=5\times 1760 yards$

$d=8800 yards$

So, distance in yards is 8800 yards..........Answer

What is the value of x in the equation 3x – y = 18, when y = 27?

atroni [7]

<span>3x – y = 18

We start by plugging in 27 for y. The goal is to isolate x by itself to solve for x.

3x - 27 = 18

Then we add 27 to both sides of the equation

3x = 45

Lastly, we divide both sides by 3 to finally isolate x by itself and solve.

x = 15</span>
