6 0

Answer:

7.5 miles

Step-by-step explanation:

Half of 5 equals 2.5. Bobby already walked 5 miles so you add the 2.5 since he walked another half of that distance. 5 + 2.5 = 7.5

Kenyon ran for 8 miles each week while training. Here is his record of the number of miles he ran.
diamong [38]

Step-by-step explanation:

Let x be the miles Kenyon ran on tuesday

Let y be the miles Kenyon ran on thursday

Given,

Mon + Tues + Wed + Thu = 8mi

1.2 + x + 1.6 + y = 8 \\ 2.8 + x + y = 8 \\ x + y = 8 - 2.8 \\ x + y = 5.2

also given,

y = x + 0.4 \\  - x + y = 0.4

Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2

Using equation 1,

x + y = 5.2 \\ x = 5.2 - y

Substitute this equation into equation 2.

- (5.2 - y) + y = 0.4 \\  - 5.2 + y + y = 0.4 \\  - 5.2 + 2y = 0.4 \\ 2y = 0.4 + 5.2 \\ 2y = 5.6 \\ y = 5.6 \div 2 \\  = 2.8mi

Substitute y = 2.8 into equation 1.

x + 2.8 = 5.2 \\ x = 5.2 - 2.8 \\  = 2.4mi

Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.

Given the function y-4=5/6(x-2), complete the table of values by entering the missing value.
mylen [45]
The first thing you do is substitute 9 for y in the function, which is,

9 - 4 = 5/6 (x - 2)

Then, you subtract on the left side

5 = 5/6 (x - 2)

Then, you multiply by 6 on both sides

30 = 5 (x - 2)

Then, divide both sides by 5

6 = x - 2

Then, at 2 on both sides to isolate x
& your final answer is

x = 8 (this would be the missing value)
