What are the values of A and B

Mathematics
1 answer:
Ostrovityanka [42]3 years ago
8 0

Answer:

Step-by-step explanation:

Multiply the denominators so you will have common denominators.

Then 5x + 11 = A(x+3) + B(x+1)

So 5x + 11 = x(A+B) + 3A + B

The only thing that has x in right is (A+B)

So A+B = 5

And 3A + B = 11

So 2A=6

And A=3

B = 5 - 3 = 2

What is the total cost of 1.2 Cubic yards of soil if it sells for $24 per cubic yard?
Kaylis [27]

Answer:

$28.80 I hope that helps if not I'm sorry if it's wrong

Step-by-step explanation:

we write "dollars per cubic yard" as "dollars/yd^3" so that the units "yd^3" will cancel when multiplying by "1.2 yd^3", leaving an answer in units of dollars

24 dollars / yd^3 * 1.2 yd^3 = 28.80

the cost would be $28.80
