-7x>4(-3x-5) do the distributive property

-7x>-12x-20 add 12 x to both sides

5x>-20 divide both sides by 5

x>-4

Hope that helps

brainliest is always appreciated

$-7x>4(-3x-5)\qquad\text{use distributive property}\\\\-7x > (4)(-3x)+(4)(-5)\\\\-7x >-12x-20\qquad\text{add 12x to both sides}\\\\5x>-20\qquad\text{divide both sides by 5}\\\\\boxed{x>-4}$

-13/24 because u have to multiply to get the same denominator which would end up being -15/24 and 2/24 add that to get -13/24

Prove that the following four points will form a rectangle when connected in order

Lemur [1.5K]

Answer:

Step-by-step explanation:

If the diagonals of the rectangle are congruent,

AC = BD

By using formula to calculate the distance between two points,

Distance between two points = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between A(0, -3) and C(2, 8),

AC = $\sqrt{(8+3)^2+(2-0)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Similarly, distance between two points B(-4, 0) and D(6, 5),

BD = $\sqrt{(5-0)^2+(6+4)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Therefore, both the diagonals are congruent.

Hence, given quadrilateral ABCD is a rectangle.

One jar holds 16 red marbles and 4 blue marbles. A second jar holds 75 white marbles and 25 blue marbles. What is the probabilit

bezimeni [28]

Jar 1 : 16 red, 4 blue....total = 20
P(blue) = 4/20 reduces to 1/5

jar 2 : 75 white,25 blue...total = 100
P(blue) = 25/100 reduces to 1/4

P(blue,blue) = 1/5 * 1/4 = 1/20 or 0.05 or 5%
