Step by step solution :

Step 1 :

Step 2 :

Pulling out like terms :

2.1 Pull out like factors :

2y + 8 = 2 • (y + 4)

Equation at the end of step 2 :

(0 - (4 • (4y - 10))) + 6 • (y + 4)

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

4y - 10 = 2 • (2y - 5)

Equation at the end of step 4 :

(0 - 8 • (2y - 5)) + 6 • (y + 4)

Step 5 :

Step 6 :

Pulling out like terms :

6.1 Pull out like factors :

64 - 10y = -2 • (5y - 32)

Final result :

-2 • (5y - 32)

AlekseyPX

The answer would be
1/3 * 9 = 3,
3^3 = 3*3*3, which then we multiply:
3*3=9, 9*3=27.
27 is the answer.

Hope this helps and have a nice day:)

Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she

Gre4nikov [31]

Answer:

Number of dimes = 34

Number of nickels = 13

Step-by-step explanation:

Total number of coins = 47

Coins are in the form of nickels and dimes.

Value of a nickel = 5 cents

Value of a dime = 10 cents

Total value of coins = $4.05 or 405 cents

To find:

Number of nickels and dimes?

Solution:

Let number of nickels = $x$

Money value of nickels = 5 $x$

Let number of dimes = $y$

Money value of dimes = 10 $y$

Total value of coins = $5x+10y$

This value is given as equal as 405.

As per question statement, the equations can be written as:

$5x+10y = 405 ..... (1)\\x+ y = 47 ...... (2)$

Multiplying equation (2) with 5 and subtracting from equation (1):

$10y - 5y = 405 - 235 \\\Rightarrow 5y = 170\\\Rightarrow y = 34$

Number of dimes = 34

Number of nickels = 47 - 34 = 13
