Thomas invested $1498.00 at 6% simple interest per annum calculate How long it will be before his investment earns $449.40
valentinak56 [21]

Answer:

t = 6 years

Step-by-step explanation:

Use the simple interest formula:  i = prt, where p is the principal, r is the interest rate as a decimal fraction, and is the elapsed time, in years.

Here we want to know how long it will take for the interest alone to reach $449.40.  We first solve i = prt for t, obtaining t = i/(pr).

Here, the length of time is t = ($449.40) / (0.06*$1498.00).  This works out to

t = 5.9947, or approximately 6 years.

t = 6 years

What is 2x+y=4 and 2x+y=-1
butalik [34]

Answer:

{x,y} = {5,6}

Step-by-step explanation:

// Solve equation [1] for the variable  x

 [1]    x = y - 1

// Plug this in for variable  x  in equation [2]

  [2]    2•(y -1) - y = 4

  [2]    y = 6

// Solve equation [2] for the variable  y

  [2]    y = 6

// By now we know this much :

   x = y-1

   y = 6

// Use the  y  value to solve for  x

   x = (6)-1 = 5
