john earns $10.26 an hour. how much will he earn if he works for 6.6 hours?

he will earn 67.71 dollars, or more precisely 67.716 dollars in 6.6 hours

Step-by-step explanation:

$67.72 or 67.71 (depends if you are taking the first 2 decimal points or if you are rounding

Step-by-step explanation:

10.26*6.6

This is done because we have how much he earns per hour and the number of hour he works so we have to multiple them together

The end result would be: 67.716 dollars. The answer varies like I said above

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
