50/90-y=5/18
Answer:
y = 5/18
Step-by-step explanation:
50/90-y=5/18
Lets simplify our fractions
50/90 = 5/9 (divide top and bottom by 10)
5/9 - y = 5/18
Subtract 5/9 from each side
5/9 -5/9 -y = 5/18 - 5/9
-y = 5/18 - 5/9
We need to get a common denominator of 18
-y = 5/18 - 5/9 *2/2
-y = 5/18 -10/18
-y = -5/18
Multiply each side by -1
-1*-y = -5/18 * -1
y = 5/18
Answer:
-8 < r < 8
Step-by-step explanation:
Let r = real number
Greater than >
r>-8
less than <
r <8
We want a compound inequality so we combine these
-8 < r < 8
Answer:
Step-by-step explanation:
Your compound inequality will include two inequalities.
These are:
x > -8
x < 8
Put your lowest number first, ensuring that your sign is pointed in the correct direction.
Next, enter your higher number, again making sure that your sign is pointing in the correct direction.
A. 3(2x + 3)(x – 1)
B. (3x + 3)(3x – 3)
C. 6(x + 1)(x – 3)
D. 6(x – 1)(x – 3)
The answer would have to be C. or D.
