X + 0.5 + 3x - 2 = 3x + 1.5
X= 3.5
Putting the all x on the right side and distributing all the numbers on the left side
Step-by-step explanation:
to be a tangent, it would have to have a 90° angle with the radius (12).
and that would make the triangle ABCenter of the circle a right-angled triangle.
and then Pythagoras must apply :
c² = a² + b²
with c being the Hypotenuse (the baseline opposite of the 90° angle). in our case the 20-line.
so,
20² = 12² + 16²
400 = 144 + 256 = 400
yes, it is confirmed, because the Pythagoras principle applies, it is a right-angled triangle, and therefore AB is indeed a tangent.
Answer:
commutative property
Explanation:
This is known as the commutative property of addition (and multiplication).
An easy way to remember the property is that the two elements commute, or exchange places, or that one element commutes from one side of the operation to the other, like a commuter (passenger) on a commuter train.
a + b = b + a
Answer:
$135
Step-by-step explanation:
first divide 36 by 8
gives you how much you earn for one hour
36/8=4.5
then multiply
4.5 by amount of hours worked
so 4.5*30=135
Greatest common factor=gcf
least common multule=lcm
with 12 and 16
factors of 12=2 times 2 times 3
factors of 16=2 times 2 times 2 times 2
greates common factor is 2 times 2=4
least common multiule means all factors combined minus repeats or 2 times 2 times 2 times 2 times 3=48
