Let's assume the temperature was 10.
it increased 25% so this is the equation for it:
10 +25%=12.5 degree.
then it decreased 40%
so it will be as follow:
12.5 degree - 40%= 7.5 degrees.
Answer:
Without any background information on the text such as what the physical environment is and what the economic activities are. I can't really help you.
$2.00 cause imagine she has 6 dollar 2/3 is 4.00 so it's 2.00
Let us take a sharp point for the graph.
In 4 hours total earning is $30.
Therefore, earnings per hours would be 30/4 = $7.5 per hour.
Are given direct variation between Total earnings(E) and Number of hours worked(h).
So, we can setup a direct variation as
Total earnings = Earning each hour * Number of hours.
Therefore, direct variation function would be
E=7.5*h.
Therefore, the direct variation function between E, the total earnings in dollars, and h, the number of hours worked is E = 7.5h.
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
