Answer:
x=21
y=45
z=101
Step-by-step explanation:
Angles crossing each other are congruent
86=4x+2
84=4x
x=21
Quadrilateral has 360 degrees
86 + 86 + 2y+4 + z-7 = 360
172 + 2y+4 + z-7 = 360
2y+4=94
2y=90
y=45
z-7=94
z=101

Using the probability concept, the number of blue balls you need to add is:
D) 5.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
A probability of 0.5 is reached if the number of red balls is the same as the number of blue balls. Current the difference is of 7 - 2 = 5, hence 5 blue balls must be added.

Step-by-step explanation:
14 : 10 : 4
Divide it by 2
7 : 5 : 2
This is the simplest form because it cannot be divided further
Answer:
x = 1
Step-by-step explanation:
-2x + 3 = -1 + 2
=> -2x + 3 = 1
=> 1 = -2x + 3
=> 2x + 1 = 3
=> 2x = 3 - 1
=> 2x = 2
=> x = 2/2
=> x = 1
Since both y squared and 6y have a common factor of y, can put that to the side and divide both the y squared and 6y to get the second step of the work shown above. Separate both the y on the outside of the parentheses and the numbers within the parentheses and set them both equal to 0 as shown in step 3 of the work shown above. Finally solve for y as you would normally. Those two number in step 4 should be your final answer.
