Answer:

2y +10 +3y-4

5y+6

Step-by-step explanation:

Answer: 5y + 6

Step-by-step explanation:

1. Distribute:

=2(y+5)+3y-4

=2y+10+3y-4

2. Subtract

=2y+10+3y-4

=2y+6+3y

3. Combine Like Terms

=2y+6+3y

=5y+6

Answer:

152. ..................

Answer:

18

Step-by-step explanation:

So what you need to find is the scale factor which is the scale of the difference between two lengths.

So Figure A is smaller than Figure B, as can be easily detected with our eyes.

Figure A has a ratio of 1/2, as 6/12 is equal to 1/2.

Since B is the original, where A is a scaled version, it must also have the same ratio of 1/2, so twice 9 is 18, which is your answer.

You can also use fractions, by making Figure A into 1/2 because 1/2 = 6/12.

Figure B can turn into 9/x.

Since you know they are scaled factors, they have the same ratio since one is scaled larger or smaller than from the original.

Since it must follow the multiplication of 2 for the side length, 9 x 2 gives your answer.

Answer:

A set of numbers used to locate a point on the coordinate plane. Also known as coordinates.

Step-by-step explanation:

Example of an ordered pair : (14,20)

The 14 is the x coordinate, which indicates the position on the horizontal line. (x - axis)

The 20 is the y coordinate, which indicates the position on the vertical line. (y - axis)

Step-by-step explanation:

Diagonal AC must be 20 feet so that ∠B will be 90°.

According to asked question, buck is creating a horse coral  by designing in such a way that corners will be at 90°.

So according to question we have to make ∠B as 90°.

So quadrilateral ABCD becomes a rectangular.

Therefore ΔABC  will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.

The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.

In the right-angle tringle ΔABC,

AC²=AB²+BC²

⇒ AC²=16²+12²

⇒ AC²=256+144=400

⇒AC=√400

⇒AC=20 feet

Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.

Answer:

Step-by-step explanation:

The original distance that Angel wanted to walk will be represented as A

Since we don't know the additional distance Angel walked it'll be represented as B

A= the amount of distance Angel wanted to walk

B= the amount of distance Angel wanted to walk past his/her challenge goal

C= the amount of distance Angel walked originally from to past her/his challenge goal

A+B=C

Example:

I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.

Answer:

Step-by-step explanation:

The probability of picking an item A in a box of N items depends on nA, the amount of items A in the box at the time of picking, with the kinda instinctive value:

p = nA / N

then it means that if you have no green ball, the probability is 0/N = 0, if you only have green balls, it means you have a probability of N/N = 1 = 100%, and if you have as many green balls as non-green balls, you have a probability of nA/(2nA) = 0.5 = 50%.

Here the probability of first picking a green ball (nG=5) in a box of N=3+5+2+6=16 for the 1st pick is:

pG1 = 5/16

Now the trick here is that once you picked the green ball, you put it back in the box before picking another ball. So you still have N=16 balls for the second pick, and the probability of picking a yellow ball (nY=6) for the 2nd pick is:

pY2 = 6/16 = 3/8

(it would have been slightly higher, at 6/15, if you did NOT put back the green marble in the box).

Now you want BOTH events to be true. So you want G1 to be true AND Y2 to be true. The two events are independent (the probability of Y2 is 6/16 if you had G1 but is also 6/16 if you failed G1), so the probability of having both is simply done by multiplicating them:

pG1Y2 = pG1 * pG2 = 15/128
