Step-by-step explanation:

3x+y=6

3x+y=6 is the new equation that has exactly one solution in common with Elena's equation. .A equation is said to have exactly one solution with this, if the set of equations meet at a point, or have a unique point of intersection. This only happens when the coefficient of x and the coefficient of y are different in the new equation. Solving these pair of equations gives us (1,2) as a unique point.

6x+2y=8

6x+2y=8 is the new equation which has no solutions in common with Elena's equation. An equation is said to have no solutions when the coefficients of both x and y are the same but the constant is different.

6x+2y=12

6x+2y=12 is the equation that has infinitely many solutions in common with Elena's equation. An equation is said to have infinitely many solutions if the result will be 0=0.

Final Amount 10,400

soldi70 [24.7K]

Answer:

$9629.63

Step-by-step explanation:

I assume this is simple interest.

The formula for simple interest is

F = P(rt + 1)

where F = future value,

P = present value

r = annual interest rate

t = number of years

10,400 = P(0.02 × 4 + 1)

10,400 = 1.08P

10,400/1.08 = P

9,629.63 = P

Gnom [1K]

Answer:

Rasheed bought 3 packages of chocolate and 5 packages of toffee.

Step-by-step explanation:

In this case we have to found the number of bars that multiplied by the fractions presented give us an integer number and meets with the fact that the bars are an odd number because the packages came in packs of two bars.

For the case of the chocolate we have to find a number that meets this characteristics, we try with the number 6:

$6*\frac{2}{3} =4$

For chocolate Rasheed bought 3 packages, we can see that 6 bars meet the asked.

For the case of toffee, we try with number 10:

$10*\frac{3}{5} =6$

For toffee Rasheed bought 5 packages, we can see that 10 bars meet the asked.

Rasheed bought 3 packages of chocolate and 5 packages of toffee.
