5.8 Nickels

Step-by-step explanation:

Let x rep no of Nickels in Mike's cup

Then x - 0.2 = Number of quarters in Mike's cup

0.2x = Amount of money that mike has from the nickels

1 ( x - 0.2) = Amount of money that Mike has from the quarter

Then,

0.2x + 1 (x - 0.2) = 6

Expand the bracket

0.2x + x - 0.2x = 6

x = 6

Recall

x - 0.2 = 0

6 - 0.2 = 5.8

Therefore, Mike has 5.8 nickels for the quarter

(1/4)^-2 - (5^0 x 2) x 1^-1 =

(4/1)^2 - (1 x 2) x 1 = 16-2 = 14

If you raise something to the power of -2, swap numerator and denominator and remove the minus.

So (1/4)^-2 = 4^2 = 16

Also 1^-1 is just 1, not -1.

Solve the equation.<br> -3x +.1 + 10x = x + 4<br> N<br> olu<br> R<br> X =<br> 18
zheka24 [161]

Answer:

Hence after solving the given equation we get <em>x = 13/20.</em>

Step-by-step explanation:

<em>Given:</em>

<em>-3 x + 0.1 + 10 x = x + 4</em>

<em>-3 x + 10 x - x = 4 - 0.1</em>

<em>6 x = 3.9</em>

<em> x = \frac{3.9}{6}</em>

<em>x = \frac{1.3}{2}</em>

<em>x = \frac{13}{20}</em>
