3a + 2(4a - 1) = 9.
Distributive property.
3a + 8a - 2 = 9
Combine like terms.
11a - 2 = 9
subtract +2 on both sides.
11a - 2 = 9
+2 +2

Inequalities are number sentences that compare two numbers. sometimes we use variables when writing inequality’s.
The experimental probability is C. 17%.
17% is derived from the following solution.
14/84 = 0.1666
0.1666 * 100% = 16.66% or 17%
This is based on the result of the experiment conducted.
The theoretical probability of A is 20%.
1/5 = 0.20
0.20 x 100% = 20%
A is only one event out of 5 letters.

Answer:
$68.32
Step-by-step explanation:
Is 9.76 = x
And the value needed is 8 * this amount, then it can be shown with 8x
8x = 9.76 * 8
8x = 78.08
So the total price is $78.08
To find the money needed, simply subtract the saved money from this amount:
78.08 - 9.76 = 68.32
So she needs $68.32!
