Correct. Use the commutative property<span> to rearrange the expression so that compatible numbers are next to each other, and then </span>use the associative property<span> to group them. Incorrect. Check your addition and subtraction, and think about the order in which you are adding these numbers.</span>

8
Step-by-step explanation:
Answer:
undefined/no solution
Step-by-step explanation:
you use elimination to solve. So multiply 2x+4y=-12 by 1 and x+2y=-2 by 2. then you subtract 2x+4y=-12 by 2x+4y=-4 and get 0y=-8. Anything divided by 0 is undefined/no solution because you can't divide anything by 0.
15% / 100% = 0.15
$140 x 0.15= $21.00
Typical tip would be $21.00
Answer:
11.33 feet
Step-by-step explanation:
The triangle for the given scenario is drawn below.
From the triangle ΔABC, AB is the length of the ladder, B is the foot of the ladder, AC is the wall, BC is the distance of the foot from the wall, and angle B is the angle of elevation of the ladder with ground.
Let the length of the ladder,
As per question, BC = 6.5 ft, °
Using cosine ratio of the angle B, we get
Therefore, the length of the ladder is 11.33 ft.
