D has the commutative property because it just flip flopped the numbers.
The 2 angles are complementary angles and need to equal 90 degrees.
Making an equation we have:
4x-10 + x = 90 degrees
Add like tems:
4x +x = 5x
Now we have:
5x-10 = 90
Add 10 to both sides:
5x = 100
Divide both sides by 5:
x = 100/5
X = 20
I hope this helps its step 2 gl
Answer:
2.3 could, but not -0.25.
Step-by-step explanation:
It is impossible to have any probability larger than 100 or lower than 0. 2.3 is possible bc it's below 100 and above 0.
The answer is 5.7 because you can only round down not up
