Step-by-step explanation:

x = 3

Answer:

[tex]x < 4[/tex]

Step-by-step explanation:

1) Subtract 2 from both sides.

[tex]5x < 22 - 2[/tex]

2) Simplify 22 - 2 to 22.

[tex]5x < 20[/tex]

3) Divide both sides by 5.

[tex]x < \frac{20}{5} [/tex]

4) Simplify 20/5 to 4.

[tex]x < 4[/tex]

So, therefor, the answer is, x < 4.

Answer:

y = 2/3x - 2

Step-by-step explanation:

Given :

Slope, b = 2/3

y - intercept, c = - 2

The equation of a line can be expressed in slope intercept form as :

y = bx + c

b = slope ; c = y - intercept

Hence, line equation becomes ;

y = 2/3x - 2

Answer:

A

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

BC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )

BC = [tex]\sqrt{225}[/tex] = 15 → A

Answer:

The bag contains 4 blue marbles, 3 green marbles, 7 red marbles, and 1 yellow marble. What is the probability of selecting a red marble and then a blue marble? Question 3 ... 4 blue marbles+ 3 green marbles+ 7 red marbles+ 1 yellow marble= 15 ... P(red,blue0 = 7/15 * 2/7 = 2/15 =.13333333 = 13.33%.

Step-by-step explanation:

Answer:

There are 14 total marbles. The probability of drawing a yellow marble on the first draw is 3/14. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of a black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.

Answer:

40%

Step-by-step explanation:

you would first simply the fraction down

13 goes into both numbers so the fraction can be simplified to

2/5 which is think is simply enough to know that 2/5 is 40% but if not the explanation would be

100÷5 =20

20 x by the 2 from the fraction

= 40%

Step-by-step explanation:

65 = 100%

0.65 = 1%

26 = x%

x = (26 ÷ 0.65)%

x = 40%

That area is the square is 25 x 25 = 625

The circle touches the square so the diameter of the circle is 25.

Area of the circle = pi x r ^2 where r is half the diameter.

Area of circle = 3.14 x 12.5^2 = 490.625

The area of the shaded region is the area of the square - area of the circle:

625 - 490.625 = 134.375 square feet.
