Answer:

81/16 = 5 1/16

Step-by-step explanation:

-4(square root of x) -3 = -12

Add 3 to both sides

-4(square root of x) = -12 +3 = -9

Divide both sides by -4

(square root of x) = -9/-4

-/- equals +

(square root of x) = 9/4

Square both sides to cancel the square root

x = (9/4)^2 = 81/16 = 5 1/16

Damien has 30 coins, all nickels and dimes. The total value of all these coins is $2.05. How many nickels does he have?

Damm [24]

Hi there!

nickels:19

We know that there is only nickels and dimes in his coin collection..

1.Multiply two terms:

$10$ · $10=1.00$

Then there would be 20 nickels but 1+1=2 not 2.05.

2.Multiply the terms:

$11$ · $10=1.10$

$19$ · $5=0.95$

3.Combine the two terms:

$1.10+0.95=2.05$

Therefore, there would be 19 nickels...

Is it possible that the orientation of a figure can change after a translation? Explain

coldgirl [10]

No, because a translation is just a slide. For the orientation to change, the shape would have to be rotated or flipped.
