Answer:
it would be B
Step-by-step explanation:
d=(0-(-5)^2+(-2-(-3)^2
d=(5)^2+(1)^2
d=25+1
d=26

Part 1 = 2/9
Part 2 =5/9
Part 3 =7/9
<u>Explanation</u>
To convert the a repeating decimals this are the steps;
Part 1
Let x = 0.222222... (i)
10x = 2.222222... (ii)
Subtract equation (i) from equation(ii)
10x = 2.222222....
<u> -x = 0.222222....</u>
9x = 2.00000..
∴ 9x = 2
Divide by 9 both sides;
x = 2/9
Part 2
Let x = 0.5555...
10x = 5.5555...
subtract equation (i) from equation (ii).
10x = 5.5555..
<u> - x = 0.5555..</u>
9x = 5.0000..
∴ 9x = 5
x = 5/9
Part 3
Let x = 0.7777....
10x = 7.7777...
Subtracting equation (i) from equation (ii)
10x = 7.7777...
<u> -x = 0.7777...</u>
9x = 7.000..
∴ 9x = 7
x = 7/9
Pattern noted
When converting the repeating decimals to fraction only one number was repeating. This made the three decimals have the same fraction.
36 is B
37 is H
Do not quote me on this, but I think the first inequality x= any number over 15
And the second one is r=4

Step-by-step explanation:
Answer:
x= 9 y=2
Step-by-step explanation:
Add up the equations vertically to eliminate y.
-x=-9
change the signs:
x=9
substitute the given value of x into the equation 2x-4y=10
2(9)-4y=10
18-4y=10
4y=8
y=2
