Question : What Is the answer to these 9th grade math problems?
1. -1(a - 10) < -10(a - 4) + 3a
2. -3 + 11(12 + 9) < 6(n + 6)
_
The answer will end up looking like this a < 7 and for number 2 its grater than or equal to.
Answer : Easy problems. 1. Solve like an equation. -1(a-10) < -10(a-4) + 3a, simplify both sides of the equation -a+10 < -10a+40 + 3a -a+10 < -7a+40 Now add a to both sides. 10 < -6a +40, subtract 40 from the right side. -30 < -6a, divide both sides by -6 (when you divide by negative number, the sign changes) 5>a. The answer is a < 5. 2. -3 + 11(12+9) <6(n+6), simplify both sides again. -3 + 132+99 < 6n + 36 228 < 6n + 36, subtract 36 from both sides. 192 < 6n, divide by 6 on both sides. 32 < n n > 32 is the answer...
