Angelo enters a relay race. He runs 8 1/2 mile every 1/2 hour. Create and complete a table to determine how many miles he will run in 1 hour, 2 hours, 2 1/2
hours, 3 hours, etc go to 5 hours.

1 Hour = 17 miles

2 Hours = 34 miles

3 Hours = 51 miles

4 Hours = 68 miles

5 Hours = 85 miles

Step-by-step explanation:

Every half hour is 8.5 miles, so for every hour you multiply 8.5 by a factor of 2. So 1 hour would be 8.5 x 2, 2 hours would be 8.5 x 4, and so on.

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

{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
