Answer:
n = 25/2, or n = 12 1/2
Step-by-step explanation:
It's essential that you use parentheses here to show how your numerals are grouped. I have made some assumptions here, and believe you meant:
(1 1/2)(n - 4 1/2) = 12.
First, convert 1 1/2 and 4 1/2 into improper fractions:
(3/2)(n - 9/2) = 12
Multiplying both sides by (2/3) eliminates the fractional coefficient (3/2):
n - 9/2 = (2/3)(12), or n - 9/2 = 8.
Again, eliminate the fraction by multiplying all terms by 2:
2n - 9 = 16
Then 2n = 25, and n = 25/2, or n = 12 1/2
X - 2 = 7 , x - 2 = - 7
x = 9 , x = - 5
Simplify both sides of the inequality.
−16x+8<2x+5
Subtract 2x from both sides.
−16x+8−2x<2x+5−2x
−18x+8<5
Subtract 8 from both sides.
−18x+8−8<5−8
−18x<−3
Divide both sides by -18.
−18x/−18 < −3/−18
x>16
Ans : x > 16
