The struggle is real smh explain in steps so I can understand please τηανκς

Answer 1

Answer:

42.  25°F

43.  5 feet

44.  $4400

Step-by-step explanation:

42.

Temp at 5PM = 20

Temp at 10PM = -5

To find the number of degrees it changed (fell), we would need to subtract the latter temperature from the first one. So, it is:

20 - (-5)

This is basically 20 + 5, which is 25 degrees.

Also, you can think, from 20 to 0, it falls 20 degrees. From 0 to -5, it falls again 5 degrees. So in total it is 20 + 5 = 25 degrees

43.

Length is given as 9.5

The length is 1.9 TIMES the width

We let the width be "w", thus we can say:

Length is 1.9 TIMES width

9.5 is 1.9 * w

"is" translates to "=", in algebra, so we can write:

9.5 = 1.9 * w

Now, we can solve for w:

$9.5 = 1.9 * w\\9.5=1.9w\\w=\frac{9.5}{1.9}\\w=5$

The width is 5 feet

44.

Current Balance = 4708

This balance is 308 MORE THAN what it was 4 years ago.

We can let the balance 4 years ago be "x".

So, we can say:

4708 is 308 MORE THAN x

In equation, we can write:

4708 = 308 + x

Now, we can solve for x:

$4708 = 308 + x\\x = 4708-308\\x=4400$

hence,

The balance 4 years ago was $4400
