It is C. The first part is raised to the 2nd power. so it goes first since that is the highest. then the -20x because variables are understood to the power of 1, while normal numbers are understood to the power of 0. so the order is highest to lowest (2,1,0)
Step 1: Subtract 3x from both sides.
−x+7=−52
Step 2: Subtract 7 from both sides.<span><span><span><span>
−x</span>+7</span>−7</span>=<span><span>−52</span>−7</span></span><span><span>
−x</span>=<span>−59</span></span>
Step 3: Divide both sides by -1.<span><span><span>
<span><span>−x</span><span>−1</span></span></span></span>=<span><span><span><span>−59</span><span>−1</span></span></span></span></span><span>
x=59</span>

Answer:
25
Step-by-step explanation:
Well, we need to simplify this. we have a ratio of 80:125.
As these numbers end in either 0 or 5, we know they are divisible by 5.
By dividing these by five, our ratio becomes 16:25.
As we have 16 jackets, we know we must need to sell 25 jackets to maintain the ratio.

The probability of selecting 2 same colors when the first is not replaced
The total number of ball is:
This is calculated as:
So, we have:
<em>Note that: 1 is subtracted because it is a probability without replacement</em>
