Please help me solve this I need some help
Agata [3.3K]

Answer:

f = 8

Step-by-step explanation:

  1. Apply the distributed property, so it now looks like this: 2f - 10 = 6
  2. Add 10 to each side, so it now looks like this: 2f = 16
  3. Divide each side by 2 to cancel out the 2 next to f. It should now look like this: f = 8

I hope this helps!

Translate each of the following into an expression or equation:
Harrizon [31]

Answer:

You have to translate these sentences into expressions.  I am not going to solve all of these because if I explain one/two problems to you, you'll get the hang of it.  Seven more than three times a number: 7+3x; Five times a number decreased by six: 5x-6

Step-by-step explanation:

Why?  We don't know what number that is, so we can put any variable like (x, y, z, a, b, etc.). Three times a number is simply that number times 3.  In this case we would input: 3*x, or 3x.  7 more than that number is 3x+7.  Five times a number decreased by six: 5x-6 .  Remember: it is simply 5*x which simplifies to 5x.  Decreased is take away, so take away 6, and get 5x-6

Key words: Quotient: the result after dividing two/or more numbers; Product: the result after multiplying two/ or more numbers; Decreased: take away (Example: x decreased by 7=x-7)

I hope you understand!! It is very simple after you start to get the hang of it!!

Angles P and Q are supplementary. If mZP is<br> 32°, what is the mZQ?
Ratling [72]

Step-by-step explanation:

Supplementary angles add up to 180°

\therefore m\angle P + m\angle Q = 180° \\ \therefore 32 \degree+ m\angle Q = 180° \\ \therefore m\angle Q = 180° - 32° \\  \huge \purple{ \boxed{\therefore m\angle Q = 148°}}
