Answer:

14(100) - 6(30)

Step-by-step explanation:

If the person earns 100 points for each question answered correctly and they got 14 correct, then you would simply multiply 100 by 14, getting 1400. Then, if they lose 30 points for each question answered incorrectly and they got 6 incorrect, you would do the same thing, getting 180.

If you need to solve this expression, the answer would be 1220. An amazing SAT score! xD (this is only a game, but still a good score)

An online store lets customers have their name printed on any item they buy. the total cost c in dollars is the price of the ite
Vsevolod [243]
So the total cost depends on the price of the item(s) (c depends on p)
The independent variable is p, the price of the item, because it is not going to depend on anything else.
The dependent variable is c, because the total cost depends on how many items there are, whether your name is marked on it, etc.
The equation would be :
c = p + $3.99

Answer:

Speed\ of\ car=38\ km/h

Step-by-step explanation:

Distance Covered by Horse:

Speed\ of\ horse=50\ km\h=50\times \frac{1000}{60}\ meter/ minute\\\\Speed\ of\ horse=\frac{2500}{3}\ meter/minute\\\\Distance\ covered\ in\ 4\ minutes=speed\times time=\frac{2500}{3}\times 4\\\\Distance\ covered\ in\ 4\ minutes=\frac{10000}{3}\ meters\\\\

Distance covered by Car:

Let\ speed\ of\ car=x\ meter/minute\\\\time=4\ minutes\\\\Distance\ covered=speed\times time=4\times x=4x

Distance\ covered\ by\ horse=Distance\ covered\ by\ car+800\\\\\frac{10000}{3}=4x+800\\\\4x=\frac{10000}{3}-800\\\\4x=\frac{7600}{3}\\\\x=\frac{7600}{3\times 4}\ meter/minute\\\\x=\frac{7600}{3\times 4}\times \frac{60}{1000}\ km/h\\\\x=38\ km/h
