The answer is x=-20.
6+ -28 -x =-2
You first add 28 to each side=6+-x=26 then you minus 6 from each side=-x=20.
Then you divide 20 by -x resulting in x=-20

$6+(-28)-x=-2\\\\\
6-28-x=-2\\\\
-22-x=-2\ \ \ |Add \ 22\\\\
-x=20\ \ \ |Multiply\ by\ (-1)\\\\
\boxed{x=-20}$

Trudy bought 1 foot of fabric. If she cuts the fabric into 3-inch pieces, how many pieces will she have?

WINSTONCH [101]

Answer:

Trudy will have 4 pieces of the fabric.

Step-by-step explanation:

Since, 1 foot of the fabric = 12 inches

If Trudy cuts the fabric into pieces of 3 inch.

Number of pieces she will have = $\frac{\text{Total length of the fabric}}{\text{Length of one piece}}$

= $\frac{12}{3}$

= 4 pieces

Therefore, she will have 4 pieces of the fabric.

Answer:

There is a 1/8 chance.

If there are 4 cards in the deck, and one three card, it makes it a 1/4 chance of picking the card the first time.

The probability stays the second time you pull out a card.

So, you would do the equation 1/4 * 1/4, which is 1/8. That is the answer.

A ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the len

masha68 [24]

Answer:

$25\text{ feet}$

Step-by-step explanation:

The ladder, ground, and building form a right triangle where the vertical distance between the top of the ladder and the bottom of the ground is one leg, the horizontal distance between the bottom of the ladder and the building is another leg, and the length of the ladder is the hypotenuse.

For any right triangle, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared ( $a^2+b^2=c^2$ ), where $c$ is the hypotenuse.

Let the length of the ladder be $\ell$ (hypotenuse of right triangle). The distance between the top of the ladder and the ground (vertical distance) can be represented as $\ell -1$ .
