A. 5/100
B. 8/100
C. 63/100
D. 108/100
WILL GIVE BRAINLIEST
Answers
Answer: B. 8/100
Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:
5/10 * 10 = 50/100
Now, we can subtract 50/100 from 58/100 to find the unknown fraction:
58/100 - 50/100 = 8/100
This gives us an answer of,
B. 8/100
You start at (0, 8). You move down 7 units and right 8 units. Where do you end?
Answers
========================================================
Explanation:
The "move down 7" means the y coordinate 8 becomes 8-7 = 1
We subtract 7 from the y coordinate.
The "move right 8 units" means we add 8 to the x coordinate to get 0+8 = 8
Therefore, the point (0,8) moves to (8, 1)

P(A and 2) = 1/12, P(D and 1) = 1/8, P(A and not 2) = 1/6
Step-by-step explanation:
P(A and 2)
There is a 1/4 chance that you hit a when you spin the spinner. There is a 2/6 chance that you hit two when you spin the spinner. 1/4*2/6 = 2/24=1/12
P(D and 1)
There is a 1/4 chance that you hit d when you spin the spinner. There is a 3/6 chance that you hit one when you spin the spinner. 1/4*3/6=3/24=1/8.
P(A and not 2)
There is a 1/4 chance that you hit a when you spin the spinner. There is a 4/6 chance that you hit anything but two in the second spinner. 1/4*4/6=4/24=1/6

y=3x-5
y=-6x-5
????
y=8x-9
y=-8x+7
???
-x+6y=21
y=-5x+12
?????
Answers
Given:
y = 3x - 5y = -6x - 5Multiplying y = 3x - 5 by 2:
=> 2(y = 3x - 5)y = -6x - 5
=> 2y = 6x - 10y = -6x - 5
Adding both equations:
=> 3y = -15Dividing 3 both sides:
=> y = -5Substitute the value of y into any equation.
y = -6x - 5=> -5 = -6x - 5=> 0 = -6xDivide -6 both sides.
=> x = 0/-6 = 0Solution (2):Given:
y = 8x - 9y = -8x + 7Add both the equations.
y = 8x - 9y = -8x + 7
2y = -2Divide 2 both sides.
2y = -2=> 2y/2 = -2/2=> y = -1Substitute the value of y into any equation.
y = 8x - 9=> -1 = 8x - 9Add 9 both sides.
=> -1 + 9 = 8x - 9 + 9=> 8 = 8xDivide 8 both sides.
=> 8/8 = 8x/8=> x = 1Solution (3):Given:
-x + 6y = 21y = -5x + 12Reorganize the first equation.
-x + 6y = 21=> 6y = x + 21Multiply the first equation by 5.
5(6y = x + 21)y = -5x + 12
30y = 5x + 105y = -5x + 12
Add both the equations.
31y = 117Divide 31 both sides.
31y = 117=> 31y/31 = 117/31=> y = 117/31Substitute the value of y into any equation.
-x + 6y = 21=> -x + 6(117/31) = 21=> -x + 702/31 = 651/31Subtract 702/31 both sides.
=> -x = 651/31 - 702/31=> -x = -51/31=> x = 51/31Find the circumference.

Find the values of x, y, and z. Round to the nearest tenth, if necessary.
Answers
Answer:
Step-by-step explanation:
The value of x is 15, y is 5 and z is 17 units in the given triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
First let us find value of y
We know that hypotensue / leg = leg/y
20/10 = 10/y
Apply cross multiplication
20y=100
y=5
Now let us find x value
20-y=x
20-5=x
x=15
The altitude is √5.15= √75
=8.6
Now by pythagoras theorem, we find value of z
x²+75 = z²
15²+75 = z²
225+75= z²
300= z²
z=17.3
Hence, the value of x is 15, y is 5 and z is 17 units in the given triangle.

Answers
Answer:
21
Step-by-step explanation:
If the angles are supplementary, that means they add up to 180 degrees.
That means if we subtract 75 from 180, we get 105.
If we divide 105 by 5, we get 21.
That means 21 * 5 + 75 = 180
or
5(21) + 75 = 180
