Wait i’m confused on what your asking?
You might be interested in
2x + y = -7 <br> 5x - y = 0 show work plz!
Zanzabum
First solve for one variable
(I chose bottom equation because it’s easier)
Get y alone: Y = 5x
Now that we have y we can plug y into the top equation
Plug in 5x for y: 2x + 5x = 7
Solve for x: 7x = 7
X = 1

Now plug in the x value into the bottom equation to solve for y
Y = 5(1)
Y= 5


So, x = 1 and y = 5

For each fraction, select the most appropriate estimate. 36 40 choose.. 1 3 choose.. 70 100 choose.. 1 8 choose.. Options: Close
sesenic [268]

Answer:

Convert each fraction to its percentage form:

= 36 / 40

= 90%

= 1/3

= 33.3%

= 70/100

= 70%

= 1 / 8

= 12.5%

Looking at the percentages:

= 36 / 40 is closest to 1.

= 1/3 <u>and</u> 70/100 are closest to one half which is 50%

= 1/8 is closest to 0.
