Solution:

5 x 70 = 5 x  7  tens

At the blank space 7.

Because 1 ten = 1 x 10

Therefore, 70 = 7 tens

70 as 7 tens

5 x 70 = 5 x  7  tens = 35 tens

Because 5 x 7 =35

As we know 35 tens = 350

Because 1 tens = 10

Therefore, 35 tens = 350

Thus, 5x70 = 350

Eric has 183 coins all of them are nickels and dimes. If the total value of the coins is 14.45, how many of each denomination co

FromTheMoon [43]

Answer:

77 nickels

106 dimes

Step-by-step explanation:

Let there be n nickes and d dimes

Since there are 183 coins, we can write:

n + d = 183

Also, the value of nickel is 0.05 and dime is 0.1, total value is 14.45, so we can write:

0.05n + 0.1d = 14.45

Solving 1st equation for n, we have:

n = 183 - d

Putting this into 2nd equation and solving for d:

$0.05n + 0.1d = 14.45\\0.05(183-d) + 0.1d = 14.45\\9.15-0.05d+0.1d=14.45\\0.05d=5.3\\d=106$

There are 106 dimes

Since, n = 183 - d

n = 183 - 106

n = 77

There are 77 nickels
