Answer:
5.1x - 1.49y
Step-by-step explanation:
We need to add or substract like terms.
like terms are the terms that have the same variable, in this case:
3.27x and 1.83x are like terms, and adding them we get:
3.27x + 1.83x = 5.1x (you add only the coefficients and the x stays the same)
we do the same for the terms with 'y':
1.28y and −2.77y are like terms, but in this case we must substract because of the − sign:
1.28y −2.77y = -1.49y
the final answer is the conjunction of the two results that we obtained:
5.1x - 1.49y
Answer:
B because they are basically the same AB = 2, there was no change, just a relfection, so A'B' = 2 as well Hope this helped

Answer:
6x + 8y
Step-by-step explanation:
Distribute 2:
Note: This means to multiply 2 with the numbers inside the parentheses.
2 * 3x = 6x
2 * 4y = 8y
Our answer would be 6x +8y
Answer:
Ans= 6720 ways
Step-by-step explanation:
From Combination rule from Permutation and Combination, nCr
We use 8^C3 or 8C3,
8x7x6x5x4x3x2x1
-------------------------- =6,720
3x2x1
or
8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
432 lb = 195.95 kg
All you have to do is use the conversion rate for pounds to kilograms. Have a nice day :)
