Kimberly is measuring the temperature fluctuations of a city
over a period of 5 days. The starting temperature of the city
was 50 degrees. Over the first two days, the temperature
decreased by 3.1 degrees each day. Then, over the
following three days, the temperature increased by 4.8
degrees each day. What was the temperature, in degrees,
on the fifth day?

Easy Peasy!

Step-by-step explanation:

First we have to set up our equation:

(Let x= Temp. after 5 days)

Sorry, have to define variables. If I didn't do it in Middle School Tests, I get an automatic 0 for that question.

So, let's solve!

(If you didn't know what I did there, I just multiplied the rate of the decreasing and increasing temperature by the number of days it was in effect)

So, the temperature during the fifth day is 58.2 degrees.

Hope this helps!

P.S. Stay Safe!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

17   x 256=4352

sorry if this is wrong, i'm new.
