Choice B) Commutative Property is the answer
The commutative property of addition says that we can add two numbers in any order. For example: 2+3 = 5 and 3+2 = 5.
In general, the rule can be written as x+y = y+x. The x and y are simply placeholders for numbers. You can think of them as empty boxes to write a number inside. In this case, we have 7.2 for one of the boxes and -5.5 as the other value in the other box.
Answer:
840 ways.
Step-by-step explanation:
For the first jar, you have 7 marbles to put in.
For the second, you now have 6 marbles to put in.
For the third, you have 5 marbles.
For the fourth, you have 4 marbles.
7 * 6 * 5 * 4
= 42 * 20
= 840 ways.
Hope this helps!

Answer:
y=5x
Step-by-step explanation:
Because it has the same slope, both equations must have 5x as their slope. The 2 equations are not going to have the same y intercept, so the +3 can be ignored and replaced with b. You want to plug in (1,5) into you new equation of y=5x+b, to get 5=5(1)+b. Multiply 5 by 1 to get 5, and then subtract 5 from both sides, which gives you 0=b. This means that the y intercept is the origin, so your new equation is y=5x
