Answer:
-1.5x + 21.5 (or (43-3x)/2)
Step-by-step explanation:
(-5/6x + 51/2) - (2/3x + 4)
<em>First, find the opposite of 2/3x + 4 because of the negative sign.</em>
-5/6x + 51/2 - 4/6x - 4
<em>Now combine -5/6x and -4/6x to get -9/6x or -3/2x</em>
-3/2x + 51/2 - 4
<em>Convert 4 into 8/2 since 51/2 is a fraction.</em>
-3/2x + 51/2 - 8/2
<em>Since the denominators of 51/2 and -8/2 are the same, just subtract 51 and 8 to get 43.</em>
-3/2x + 43/2
<em>-3/2x and 43/2 have the same denominator (2), so you can just put it like this (It's up to you!):</em>
(43-3x)/2
The answer to (-5/6 + 51/2) - (2/3x + 4) is -3/2x + 43/2 (or (43-3x)/2)
<em>Or you could put it like this (I converted both -3/2 and 43/2 to a decimal.)</em>
-1.5x + 21.5
Answer:
y=-1/2x+2
Step-by-step explanation:
If you are supposed to put it in slope-intercept form,(y=mx+b), then this would be the answer because the slope (m) is -1/2, and the y intercept is 2. I hope this helps :).
Answer:
2a + 2b + 6c.
Step-by-step explanation:
To find this we subtract :-
3a + 5b + 7c - (a + 3b + c)
= 3a + 5b + 7c - a - 3b - c Now combine like terms:
2a + 2b + 6c (answer).
