The variable represents something that is unknown. If I want to know what to subtract from 13 to get 10, I would say 13-X=10
In this problem the Variable is X, but you can use any letter or symbol, I would not use "S", "O", or "l" to represent a variable, because they can look like 5, 0, and 1.
Answer:
Option A. 10%
Step-by-step explanation:
Number of trials done with a spinner which has 5 sections labeled as A, B, C, D and E.
Since Trials done for the outcome of E is 6 therefore the probability of spinner landing at E will be
P = Outcome for E/ total number of trials done
P = 6/60 = 0.10
Or P = 10%
Therefore option A. 10% is the correct option.Step-by-step explanation:
Answer:
x=18, y=9
Step-by-step explanation:
The lines of y+3 and 12 look equal to each other. So do x-3 and 15. Because of this, we set each equal to each other and solve.
solving for x:
x-3 = 15
+ 3 +3
x=18
solving for y:
y+3=12
- 3 -3
y=9
hope this helps!!!
Pythagoreon theorem
a^2+b^2=c^2
5^2+10^2=125 not 20^2
Answer:
x^2 + y^2 = 25
Step-by-step explanation:
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can see that the center is (0, 0) by looking at the graph, and the radius is 5 because it is marked. Plugging these in we get:
x^2 + y^2 = 25
