Juan bought 4 pounds of chocolate
Andru [333]

Answer:

Step-by-step explanation:

This is a system of equations.  The 2 equations are:

4c + 2p = 16

2c + 3p = 12

Let's get rid of the p's first.  Do this by multiplying the first equation by -3 and the second equation by 2 to get a new system that looks like this:

-12x - 6p = -48

 4c + 6p =  24

Now add to get

-8c = -24 and

c = 3

That means that chocolate is $3 per pound.  Now sub that back in to either one of the original equations to get the price for peanuts:

4(3) + 2p = 16 and

12 + 2p = 16 and

2p = 4 so

p = 2

The price for peanuts is $2 per pound.

Find the equation of the line with a slope of 12 that passes through the point (3, -1)
Anon25 [30]

Answer:

y = 12x - 37

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 12, thus

y = 12x + c ← is the partial equation

To find c substitute (3, - 1) into the partial equation

- 1 = 36 + c ⇒ c = - 1 - 36 = - 37

y = 12x - 37 ← is the equation of the line

Prince Charming invests $3000 for 5 years at a rate of 4% per year simple interest.
ELEN [110]

Answer:

$ 600

Step-by-step explanation:

From the question given above, the following data were obtained:

Principal (P) = $ 3000

Time (T) = 5 years

Rate (R) = 4%

Interest (I) =?

The total interest he will receive can be obtained as follow:

I = PTR/100

I = 3000 × 5 × 4 / 100

I = 60000 / 100

I = $ 600

Thus, the total interest he will receive is $ 600
