36 - (-20) = 56
SO the number that should be added to -20 to get the answer of 36 is 56.

Flipping a coin is an independent event, meaning the probability of getting heads or tails does not depend on the previous flip. It's 1/2 or 0.5 chance every time.
So three coin flips would be = (0.5)*(0.5)*(0.5)
= 0.125
× 100%
= 12.5% chance
Answer:
393/1000
Step-by-step explanation:
Answer:
- X Greater-than-or-equal-to 12
- A closed circle is used on the graph.
- The arrow on the graph points right.
Step-by-step explanation:
This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.
x -2.6 ≥ 9.4
x ≥ 12.0 . . . . . . add 2.6 to both sides
The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.
The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.
The true statements are ...
- X Greater-than-or-equal-to 12
- A closed circle is used on the graph.
- The arrow on the graph points right.
X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25
x + y = 47
25 + y = 47
y = 47 - 25
y = 22
ur numbers are 22 and 25
