Lina20 [59]

In this question, it is given that

Walter wants computer software that cost $129. He has $57 saved.

he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

15x+57 \geq  129

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

15x\geq  72

Dividing both sides by 15.

x \geq   4.8\

Correct option is A.

If a TV has 200 ft by 875 ft what is the total mass of it
mafiozo [28]
There's no way to find the mass with the information given.
"200 ft" and "875 ft" are linear dimensions ... things you would
measure with a ruler.  They tell us how long or wide or high the
TV is.  None of that information tells us anything about its mass.

By the way ... those are gigantic measurements.  I was working
in Wrigley Field here in Chicago just before opening day in 2015,
when the new video screens were being installed.  I saw them
up close while the cranes lifted them into position.  None of the
Chicago Cubs' new screens is as big as the numbers in the question,
and I'm pretty sure the whole score-board isn't that big either.
Something is definitely wrong here.
