Since the area of a square is side squared, you can find the length of each side by finding the square root of the area, which is 5. Since there are four sides in a circle, just multiple 5 by 4 and your answer is 20 units.
Answer: x = 23 and y = 13
Explanation:
let x and y be the two number.
Where:
(x + y)/2 = 18 => x + y = 18 x 2 = 36
and:
x - y = 10
Thus we get:
x + y = 36 (1)
x - y = 10 (2)
Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23
If x = 23
then x - y = 10
23 - y = 10
-y = -13
y = 13
Answer:
15° C.
Step-by-step explanation:
To do this, we will need to plug in and solve.
59 = 9/5c + 32
Isolate the variable by subtracting 32 by both sides:
27 = 9/5c.
Divide both sides by 9/5, giving you:
15° C.
Answer:
x=3
Step-by-step explanation:
-2x+3=x-6
-3x+3=-6
-3x=-9
-x=-3
x=3
Simplify the equation to n-6=4n+18
subtract 4n from both sides
n-6-4n=4n+18-4n
-3n-6=18
add 6 to both sides
-3n-6+6=18+6
-3n=24
divide both sides by -3
-3n/3=24/-3.
n=-8
hope this helps!
