Answer:
A.
Step-by-step explanation:
3x + x - 13 + 4 - 6x = 12
we try to combine the elements with the same power of x (including the ones without any x) :
3x + x - 6x
-13 + 4
so, we get
-2x - 9 = 12
-2x = 21
x = -21/2
It would be rounded to 300,000
They are all divisible by 3...thats something
Answer:
6ab + -3a2
Step-by-step explanation:
2ab(4a2 + 3ab - 7b2) original problem
2ab(3ab + 4a2 - 7b2) commutative property
2ab(3ab + -3a2) subtract
4 - 7 = -3
6ab + - 3a2 mulitiply
2ab x 3ab = 6ab
and that is you final expression, you can't add the last 2 numbers cause they are not like terms.
First, you have to turn all of the weights from the unit that they are into ounces.
sandwich weighs 0.462 lbs is 7.392 ounces
sneaker weighs 290.87 g is 10.260 ounces
pinecone weighs 0.0000453 ton is 1.450 ounces
dog collar 0.246 kg is 8.677 ounces
Once you add these up you get 27.779 as a total which means the answer is D or 27.78 when you round to two decimal places.
