Answer:
x = 5/2
Step-by-step explanation:
2^x+4 = 2^3x-1
x + 4 = 3x - 1
3x - x = 4 + 1
2x = 5
x = 5/2
Answer:
No
Step-by-step explanation:
96+88+74+76=334/4=83.5
96+88+74+76+100=434/5=86.8
The average can't be higher than a 91%
Answer:
z = 61
Step-by-step explanation:
The exterior angle is congruent (equal to) the sum of the 2 farthest angles from it, so you can set the equation like this:
z + z - 11 = z + 50
Add like terms, which would be the 2 "z's" on the left side:
2z - 11 = z + 50
Then subtract the z on the right side from both sides:
2z - 11 = z + 50
-z -z
___________
z - 11 = 50
Add 11 to both sides:
z - 11 = 50
+ 11 +11
________
z = 61
Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is 
.
Now we need to find the radius of the given circle .
To find that let's compare with the formula of the circle with is 
, where r is the radius.
We get 
take square root of both sides.
Hence radius of the given circle is r = 2.
