27.99x.075= 2.09925 or 2.10 Rounded
27.99+2.10= $30.09
the answer is b
X is a bigger number and the difference between x and y is 7, so x-y=7. And it says that the sum of two numbers is 31 so x+y=31
Answer:
- x ≥ 0: x|x| = x²
- x < 0: x|x| = -x²
Step-by-step explanation:
<u>For x ≥ 0</u>
|x| = x
so
x|x| = x(x) = x²
<u>For x < 0</u>
|x| = -x
so
x|x| = x(-x) = -x²
Let's solve your equation step-by-step.<span><span><span><span>6n</span>+n</span>+14</span>=0</span>
Step 1: Simplify both sides of the equation.<span><span><span><span>6n</span>+n</span>+14</span>=0</span><span>Simplify: (Show steps)</span><span><span><span>7n</span>+14</span>=0</span>
Step 2: Subtract 14 from both sides.<span><span><span><span>7n</span>+14</span>−14</span>=<span>0−14</span></span><span><span>7n</span>=<span>−14</span></span>
Step 3: Divide both sides by 7.<span><span><span>7n</span>7</span>=<span><span>−14</span>7</span></span><span>n=<span>−2</span></span>
Answer:<span>n=<span>−<span>2</span></span></span>
