[tex]\frac{AC}{CD}= \frac{AB}{BD}[/tex]
[tex]\frac{8}{4}=\frac{x+3}{x-4}[/tex]
8(x - 4) = 4(x + 3)
8x - 32 = 4x + 12
8x - 4x = 32 + 12
4x = 44
x = 11
Therefore, value of x is 11.

The sum of a number and two is equal to negative seven. Translate this sentence to an equation and then find the number.
Answers
Answer: -9
Step-by-step explanation:
Given
The sum of a number and two is equal to negative 7
Suppose x is that number
[tex]\therefore x+2=-7\\\text{add -2 both sides}\\\Rightarrow x+2-2=-7-2\\\Rightarrow x=-9[/tex]
So, the number is [tex]-9[/tex].

Answer:
option A : 7x - 1
Step-by-step explanation:
Area of the shaded region = [ Area of bigger rectangle] - [Area of smaller rectangle ]
Therefore, Area of bigger rectangle = length * breadth = (x - 1)(x + 5)
Therefore, Area of smaller rectangle = length * breadth = (x + 1)(x - 4)
Area of shaded region = [(x - 1)(x + 5)] - [(x + 1) ( x - 4)
= [x(x + 5) - 1(x + 5)] - [x(x - 4) + 1( x - 4)]
= [ x^2 + 5x - 1x -5] - [ x^2 - 4x + 1x - 4]
= x^2 + 5x - 1x - 5 - x^2 + 4x - 1x + 4 ....(after removing the brackets)
= x^2 - x^2 + 5x + 4x - 1x - 1x - 5 + 4.....( as (+ x^2 )and (- x^2 )get eliminated due to opposite signs)
= 9x - 2x - 1
= 7x - 1
So, option A: 7x - 1 is the correct answer.

The measure of an angle is 2.8.what is the measure of its complementary angle
Answers
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answers
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units
A bag contains 6 white marblesw and 4 black marbles.a marble is drawn from the bag and then a second marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw and another white marble on the second draw
Answers
Answer:
60.5%
Step-by-step explanation:
60% white, 40% black
The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

Area of figure 2 = 150 square cmWX = 25/6 cm (exact)WX = 4.167 (approximate)It's not clear which version of WX your teacher wants, so I provided both of them.
============================================================
Explanation:
Focus on the perimeters. The jump from 36 to 30 means the linear scale factor is 30/36 = 5/6
This means,
WX/YZ = 5/6
WX/5 = 5/6
6WX = 5*5
6WX = 25
WX = 25/6 which is exact
WX = 4.167 approximately
---------------
The linear scale factor is 5/6, so the area scale factor is (5/6)^2 = 25/36.
The area of figure 1 is 216 cm^2, making the area of figure 2 to be 216*(25/36) = 150 cm^2
