6n + 9 = -3 - 21 - 6

Mathematics
1 answer:
denis23 [38]3 years ago
3 0
6n+9=-3-21-6
subtract the numbers:-3-21-6=-30
6n+9=-30
subtract 9 from both sides
6n+9-9=-30-9
simplify
6n=-39
divide both sides by 6
\frac{6n}{6}= \frac{-39}{6}
n= \frac{-13}{6}
decimal n=-6.5
Hope this helps :)

Which equation represents the function represented by the table? 17 POINTS!!!
dybincka [34]

Answer:

  f(x) = -x -1

Step-by-step explanation:

You can make the correct choice by seeing which equation works for the first line of the table.

  f(-1) = -(-1) -1 = 0 . . . . . the first equation works

  f(-1) = -(-1) +1 = 2 . . . not zero

  f(-1) = -1 -1 = -2 . . . not zero

  f(-1) = 1 -(-1) = 2 . . . not zero (same as second equation)

A piece of fabric is 1/3 yard by 3 5/8 yards. Irma solves 1/3⋅3 5/8 to find the area of the fabric in square yards. Enter number
Harlamova29_29 [7]

For this case we have:


The area of the piece of fabric is given by A = a * b


Where


a = \frac{1}{3}yards


b = 3 \frac{5}{8}yards


Substituting in the formula of the area we have:


A = \frac{1}{3}* 3 \frac{5}{8}\\

A = \frac{1}{3}* (3 + \frac{5}{8})\\

A = 1 + \frac{5}{24}


A = 1\frac{5}{24}yards ^ 2\\

Thus, the area of the piece of fabric is given by: A = 1\frac{5}{24}yards ^ 2\\

Answer:


A = 1\frac{5}{24}yards ^ 2\\
