Simplify a-{3a-[4a-(2a-4a)]}

Start from the inside and work your way out.
we would start with simplifying (2a-4a) first, giving us (-2a) instead of the previous.
(4a-(-2a)) would give us a positive 6a.
(3a-6a) would give us a (-3a)
a-(-3a) would leave us with a simplified 4a.
that's the answer, hope that helped!! xx

Digiron [165]

Answer: $\frac{17}{35}$

Step-by-step explanation:

Given

The bag contains 6 orange and 9 lime sweets

For both sweets of the same flavor, Jodi must either choose orange or lime

No. of ways it can be done is $^6C_1\times^5C_1+^9C_1\times^8C_1$

The total no of ways of selecting two sweets out of 15 is $^{15}C_1\times^{14}C_1$

The probability that both sweets are the same flavor

$P=\dfrac{^6C_1\times^5C_1+^9C_1\times^8C_1}{^{15}C_1\times^{14}C_1}=\frac{102}{210}=\frac{51}{105}=\frac{17}{35}$
