Complete question :

The temperature at 5:00 a.m. was –6 °F. By 3:00 p.m., the temperature had risen to a high of 36 °F. If the temperature at 8:00 p.m. decreased from the high by the change in temperature in Fahrenheit degrees from 5:00 a.m. to 3:00 p.m., what was the temperature at 8:00 p.m.?

Answer:

-6°F

Step-by-step explanation:

Temperature at 5am (t1) = - 6°F

Temperature at 3pm (t2) = 36°F

Change in temperature, between 5am and 3pm:

(t2 - t1) = (36 - (-6)) = (36 + 6) = 42°F

Hence, temperature at 8:00 pm:

High temperature - change in temperature between (5am - 3pm)

36°F - 42°F = - 6°F

We were never taught this in class, and I understand it, kind of... but i'm just confused with everything.

Nitella [24]

Its alright, You are doing better than a whole bunch of people
you know why?
because you realized you needed help and asked.

Now, aside from mushy pep talk, let me help you a bit.

When multiplying numbers with exponents, its the same as adding the exponents so $x^{2} * x^{3} = x^{5}$
cool right?

now you can take your answer $\frac{ x^{5} y^{10}}{ x^{9} y^{5}}$

Remember though, if you don't see the exponent, it is 1, not zero.

so if you noticed, $x * x^{8} = x^{9}$
just remember that and you should be fine

also, if you have to simplify more, and example would be $\frac{ x^{2} }{x} = x$

you get that from subtracting the $x^{1}$ from the top $x^{2}$

BUT

if it is $\frac{ x^{2} y^{2} }{ x^{2}}$ YOU DO NOTHING this is because that $x^{2}$ on the top is being multiplied by $y^{2}$ , which means it changes the equations value

Question 4 of 10

alukav5142 [94]

Answer:

Step-by-step explanation:

1. Add the costs together 10.98+13.95+22.56=47.49

2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.

47.49/3=15.83

The option closest to our number is D so we round up.

$15.83->$20
