Answer:
X <= 4
Step-by-step explanation:
-3x - 24<= -36
Make -3x the subject, by carrying -24 to the other side
Note: Moving -24 to the other side changes to + 24
-3x <= -36 + 24
-3x <= - 12
Minus cancels minus
3x <= 12
Divide both sides by 3,to get the value of x
3x/3 <= 12/3
x <= 12/3
x <= 4
Therefore, x equals to 4
You do add the two negatives and get a negative answer but -3 + -5 = -8
Answer:
0.7x/0.8y = x/y * 0.7/0.8 = x/y * 0.875
So the fraction is reduced by 12.5%
