There are 120 children there are twice as many boys than girls how many girls are there?

Answers

Answer 1

Answer: Boys are b
Girls are g

b + g = 120
2g = b

Substitute the second equation into the first

2g + g = 120
3g = 120
g = 40

Plug in g = 40 and solve for b

b + g = 40
b + 40 = 120
b = 80

There are 40 girls and 80 boys.

A car manufacturer rolled out a new car priced at $10,000, but not many people bought it. In the context of supply and demand, how might the price of the car be affected?

Answers

Not a lot of people bought the new car making it undesirable dropping the price in the context of supply and demand.

The price would go down.

Answer:

The price of the car goes down or will decrease in order to increase the demand of the supplied cars.

Step-by-step explanation:

It is given that:

A car manufacturer rolled out a new car priced at $10,000, but not many people bought it.

So, in context of the supply and demand if the the demand decreases the price of the item also decreases and hence by doing so if the price of an item decreases the demand again will increase.

Hence, with the decrease in demand:

The price of the car will decrease.

Answer:

True

Step-by-step explanation:

Start by narrowing the equasions down, add all the numbers together:

1s + 1s + 1s + 1s = 4s

4s = 4s

Both equasions are equivelent to 4s, so the answer would be True.

If you had trouble understanding that, here is another way:

First lets set a control number for s, like 3. then we are going to place the control into the equasion:

1(3) + 1(3) + 1(3) + 1(3)

4(3)

Now solve:

1(3) + 1(3) + 1(3) + 1(3) = 12

4(3) = 12

Both equasions are equivelent to 12, so the answer would be True, they are equivelent.
