7x(x−1)
Step-by-step explanation:
Answer:
There were 16 birds at the shelter on Wednesday.
Step-by-step explanation:
Number of cats and birds on Wednesday = 34
let the number of birds on Wednesday = b
Then number of cats = (34 -b)
The rate of taking care of each bird in shelter = $3
The rate of taking care of each cat in shelter = $7
Total amount spent by shelter on Wednesday = $174
So, according to the question
b x ($3) + (34 -b) ($7) = $ 174
or, 3b + 238 - 7b = 174
or, 4b = 64
⇒ b = 64/4 = 16
Hence, the number of birds in shelter on Wednesday = b = 16
and Number of cats = 34 - 16 = 18
Answer:
Answer is D 2x^3 + 7x^2 - 23x + 12
Step-by-step explanation:
(x^2 + 5x - 4)(2x - 3)
Expand by multiplying each term in the first expression by each term in the second expression.
The easy way would be multiplying the first expression by 2x then set those numbers off to the side.
Then multiply the first expression by -3 and set those numbers off to the side as well.
Then add the numbers you put off to the side together.
This should result in: 2x^3 - 3x^2 + 10x^2 - 15x - 8x + 12
Combine the alike terms together
=2x^3 + 7x^2 -23x + 12
To solve this problem, set up and solve a system of equations. The variables b and m will represent a bread loaf and milk jug, respectively:

I would solve using substitution. Take one of the equations and set it equal to one of the variables, for example:

Now, plug this into the other equation for m and solve for b:

We now know that a loaf of bread costs $2.50. Plug this value in for b in the first equation and solve for m:

One jug of milk costs $1.50 and one loaf of bread costs $2.50.
