Methods:

3x-2=13

=> 
3x-2+2=13+2

=> 
3x+0=15

=> 
3x=15

=> 
\frac{3}{3}x= \frac{15}{3}

=> 
x =  \frac{5}{1} or 5

or, (do side changing)

3x-2=13

=> 3x=13+2

=> 3x=15

=> x= \frac{15}{3}

=> x= \frac{5}{1} or 5

What is the equation of the line represented by the table below? X -2 -1 0 1 2 - y 16 11 6 1 -4 O A. y = -5x+9 OB. y = -5x+6 O C
Nina [5.8K]

Option (c) is the correct answer

The equation y = -5x + 6 is represented by the given table i.e.

x   -2   -1   0   1   2

y   16   11   6   1  -4

Given, a table

x   -2   -1   0   1   2

y   16   11   6   1  -4

Now, we have to find the equation of the line, satisfying the given values

As, the equation

y = -5x + 6 satisfying the given set of values,

So, the equation y = -5x + 6 is represented by the given table.

Hence, the equation y = -5x + 6 is represented by the given table.

Brandon has a total of $3.28 consisting of an equal number of pennies nickels dimes and quarters.How many coins does he have in
kiruha [24]

9514 1404 393

Answer:

  32 coins

  consider the value of a group of coins

Step-by-step explanation:

The coins are in equal numbers, so they can be considered as a group. The value of one group of 4 coins is ...

  1¢ + 5¢ + 10¢ + 25¢ = 41¢ = $0.41

Then the number of groups (g) of coins is ...

  $3.28 = $0.41×g

  g = $3.28/$0.41 = 8

There are 8 groups of coins. Each group has 4 coins, so there are ...

  (8 groups)×(4 coins/group) = 32 coins
