The correct answer is: x < 1.25
To solve this, we following the same steps as when solving inequalities. We just have to remember to reverse the sign if we multiply or divide by a negative number.
-1.2x - 8.2 > -9.7
-1.2x > -1.5
x < 1.25
<h2>A.</h2>
So let's break down this sentence (Let n = unknown number):
- "A number is doubled and then 1 is added to it"; Remember that double means multiplied by 2. With this sentence, we can determine that "2n + 1" is a part of the equation.
- "The answer is divided by 5, and then increased by 16"; The "answer" they refer to is "2n + 1" from the prior sentence. Since this is divided by 5 and <em>then</em> added by 16, we can determine that
is a part of our equation. - "The final result is 18"; This means that the prior part of the equation is equal (=) to 18. <u>With this info, our full equation is
</u>
<h2>B.</h2>
Now, let's solve our prior equation found in A. To solve for the unknown number, n, we need to isolate the variable onto 1 side of the equation. Firstly subtract both sides by 16 to cancel out the + 16 on the left side:

Next, multiply both sides by 5 to cancel out the division on the left side:

Next, subtract both sides by 1 to cancel out the + 1:

Lastly, divide both sides by 2 to cancel out the multiplication:

<u>In short, the number is 9/2 or 4.5.</u>
Multiply by .22 then add that answer to what you multiplied. For example, you need to increase 100 by 22%. 100 × .22 = 22. 100 + 22 = 122

Answer:
a = 8
Step-by-step explanation:
a + 7 = 15
a + 7 - 7 = 15 - 7 Subtract 7 from both sides.
a = 8
