Tems11 [23]

Answer:

78 emails

Step-by-step explanation:

Given

Represent sent emails with x and received with y.

So, we have:

$x + y = 114$ -- First statement

$y = 6 + 2x$ -- Second statement

Required

Determine the number of emails received (y)

Make x the subject in $x + y = 114$

$x = 114 - y$

Substitute 114 - y for x in $y = 6 + 2x$

$y = 6 + 2(114 - y)$

Open bracket

$y = 6 + 228 - 2y$

Collect Like Terms

$2y+y = 6 + 228$

$3y = 234$

Divide by 3

$y = 234/3$

$y = 78$

Bailey just ran four miles outside. Her time for each mile was 9.05 / 8.24 / 10 / 9.22. How long did it take for her to run all

larisa86 [58]

Answer:

36.51

Step-by-step explanation:

If Bailey ran four miles, then the time that is given for each of her miles should be added together to find out her total time.

9.05 + 8.24 + 10 + 9.22

You can break it down into chunks to make it easier for you:

9.05 + 8.24

= 17.29

___________

9.22 + 10

= 19.22

_________________________________________________

Then you can just add both values together to find out the total

_________________________________________________

17.29 + 19.22 = 36.51
