Where does the 1 come from in (1.0325)

NemiM [27]

Answer: *1*.0325

Step-by-step explanation: When you round it to the nearest tenths place the 3 behind the 0 is less than 4 therefore everything behind the 0 gets taken away. The 0 has no value so you could take it away too along with the decimal point and it will turn into just 1.

Solve |p + 2| = 10Solve |p + 2| = 10 {-12} {-8, 8} {-12, 8}

valentinak56 [21]

By definition, we have

$|p+2| = \begin{cases} p+2 &\text{ if } p+2 \geq 0 \\-p-2 &\text{ if } p+2 < 0 \end{cases}$

So, we have to solve two different equations, depending of the possible range for the variable. We have to remember about these ranges when we decide to accept or discard the solutions:

Suppose that $p+2\geq 0 \iff p \geq -2$

In this case, the absolute value doesn't do anything: the equation is

$p+2 = 10 \iff p = 10-2 = 8$

We are supposing $p \geq -2$ , so we can accept this solution.

Now, suppose that $p+2 < 0 \iff p < -2$ . Now the sign of the expression is flipped by the absolute value, and the equation becomes

$-p-2 = 10 \iff -p = 12 \iff p = -12$

Again, the solution is coherent with the assumption, so we can accept this value as well.

Ivahew [28]

Let's solve your equation step-by-step.−w+4(w+3)=−12Step 1: Simplify both sides of the equation.−w+4(w+3)=−12Simplify: (Show steps)3w+12=−12Step 2: Subtract 12 from both sides.3w+12−12=−12−123w=−24Step 3: Divide both sides by 3.3w3=−243w=−8Answer:w=−8
