Answer: 11/5
Step-by-step explanation:
you would do (2) times (5) to get 10.
then you'd add 1+10 to get 11.
write this new number as the numerator... 11/5.
Subtract x from both sides:
(3x - x) + 7 = (x - x) - 1
3x - x = 2x:
2x + 7 = (x - x) - 1
x - x = 0:
2x + 7 = -1
Subtract 7 from both sides:
2x + (7 - 7) = -7 - 1
7 - 7 = 0:
2x = -7 - 1
-7 - 1 = -8:
2x = -8
Divide both sides by 2:
2x / 2 = -8 / 2
2 / 2 = 1:
x = -8 / 2
The gcd (greatest common denominator) of 8 and 2 is 2:
-8 / 2 = 2(-4) / 2x1 = 2/2 x - 4 = -4
x = -4
Answer: a) x < 3
b) 3, 4, 5, 6
c) x > 6
<u>Step-by-step explanation:</u>
First you need to understand the symbols:
< means less than (represented by an open dot, left arrow)
≤ means less than or equal to (represented by a closed dot, left arrow)
> means greater than (represented by an open dot, right arrow)
≥ means greater than or equal to (represented by a closed dot, right arrow)
a) We have a closed dot and a left arrow so we need to use <
We write this inequality as: x < 3
b) y is BETWEEN 2 and 6 (not including 2 but including 6)
2 <u> </u><u>3 </u> <u> 4 </u> <u> 5 </u> 6
c) 3x + 7 > x + 19
2x + 7 > 19 subtracted x from both sides
2x > 12 subtracted 7 from both sides
x > 6 divided both sides by 2
