Ehh, now it's letting me answer.
So the associative property is basically as long as it's addition or multiplication, you can move around the groupings and it will still be the same.
For example, you can say:(21 * 7) (3x) instead of (21)(7)(3x)
And it would be equal to the old version.
(To answer your other question, the commutative property is you can move around all the parts of the equation as long as it's addition or multiplication.)
So basically, it would be the first one you sent me.
Answer:
17
Step-by-step explanation:
|-2|=2
|15|=15
2+15=17
A is the right option! Because 0.40 should be in second equation with the x to represent the number of stamps multiply by 40 cents.
<u><em>Step-by-step explanation:</em></u>
- Since the triangle is right use the tangent ratio to solve for x
- Multiply both sides by
x × 
( divide both sides by 
)
x = ≈ ( nearest tenth )
2(3x+2) I couldn’t find any other ones, your best bet would be to go into decimals or fractions if you want to find more.
