Answer:
Proportional relationships are relationships between two variables where their ratios are equivalent.
Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!
Answer:
the answer is B. 75
Step-by-step explanation:
Answer:
7y + 5z + 10
Step-by-step explanation:
2y + 7z - 2z + 4y + 8 + y + 2
Like terms are terms that have the same variable part.
2y, 4y, y are like terms (remember that y is the same as 1y when you add)
7z, -2z are like terms
8, 2 are like terms
2y + 7z - 2z + 4y + 8 + y + 2 =
= 2y + 4y + y + 7z - 2z + 8 + 2
= 7y + 5z + 10
28oz=0.793787 kilograms
280z=793.787 grams
(in case you need to show work)
1oz=28.3495grams
1oz=0.0283495
