Answer:
x=27
Step-by-step explanation:
The two angles are vertical angles, which means they are equal
4x+7 = 5(x-4)
Distribute the 5
4x+7 = 5x-20
Subtract 4x from each side
4x+7 -4x = 5x-4x -20
7 = x-20
Add 20 to each side
7+20 =x-20+20
27 = x
If the question is looking for an absolute value then the answer is 12.
Absolute value |-a| = a.
Answer:
We need to first find the radius:
half of 12(diameter) = 6 your new radius.
Formula of a circumference:
2πr
In this case
pi is 3.14 and your radius is 6 and 2 is just 2.
2 x 3.14 x 6 = 37.68 inches.
Ricardo, because 2/3 > 2/4.
This is because if you divide 2 by 3, you get 0.666. If you divide 2 by 4, you get 0.5
if you multiply both by 10, you get the percentile, in which case Ricardo has read 66% and Lin has read 50%. :)
