-2(x-4)=-16<br> SOLVE FOR X!!
Andrej [43]

Answer:

x = 12

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

-2(x - 4) = -16

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute -2:                    -2x + 8 = -16
  2. Isolate <em>x</em> term:                  -2x = -24
  3. Isolate <em>x</em>:                           x = 12

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    -2(12 - 4) = -16
  2. Subtract:                       -2(8) = -16
  3. Multiply:                        -16 = -16

Here we see that -16 does indeed equal -16.

∴ x = 12 is a solution of the equation.

Jay spent ten more than three times the number of hours on his science fair project than jamie spent on her project jay spent 43
Aliun [14]
Why did both of their names have to start with the same letter

x=jay hours
y=jamie huours

x=10+3y
x=43


so
43=10+3y
minus 10
33=3y
divide 3
11=y

jamies spent 11 hours

Find the value of X round your number to the nearest tenths<br><br><br> Explain it please
Anarel [89]

In this case, we must use trigonometry to find the value of x:

        tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24

Thus the value of x rounded to the nearest tenth is <u>8.2</u>

<u></u>

Hope that helps!
