Answer:

A is neither, B is direct, and C is inverse

Step-by-step explanation

In B, as x increases y also increases, in C as x increases y decreases, and in A it's neither because it's not one line (if you graphed it you would understand what I mean).  Though I have no idea what is constant of variations.

Use the formula . Find t for r = 33.2 m/h and d = 375.16 m.
Butoxors [25]

\boxed{t=11.3h}

<h2>Explanation:</h2><h2></h2>

In this problem we have the following data:

r:speed \\ \\ d:distance \\ \\ t:time \\ \\ \\ r=33.2m/h \\ \\ d=375.16m \\ \\ \\ So \ our \ goal \ is \ to \ find \ t

Speed, time and distance are related with the following formula:

r=\frac{d}{t} \\ \\ \\ Solving \ for \ t: \\ \\ t=\frac{d}{r} \\ \\ t=\frac{375.16}{33.2} \\ \\ \boxed{t=11.3h}

a suit is being sold at a 20 % off (discount). The sale price is $ 270. What was the original price ?
Lisa [10]

Answer:

The original price is 337.50

Step-by-step explanation:

If we get 20% off, we still have to pay 100-20 =80%

Let x be the original price

x *80% = 270

.80x = 270

Divide each side by .80

.80x/.80 = 270/.80

x =337.50

The original price is 337.50

Four more than three times n equals -5
Verizon [17]
3n+4=-5

do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.

-5-4=-9

since 4-4=0, we can take 4 out of the equation. now you have:

3n=-9

now divide -9 by 3

-9/3=-3

n=-3

hope this helps :)
