Answer:
D. 9p + $11.50 = $94.75; p = $9.25
Step-by-step explanation:
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter D.
...................................................................................................................................................
Let
p---------> the price of each scrub
s----------> the price of the potting soil
T--------> total bill
we know that
in this problem
substitute the values in the formula above
solve for p
therefore
the answer is the option D

Answer:
(-5-5x)/(4x+3
Step-by-step explanation:
Replace x with y to get (-3y-5)/(4y+5). Solve for y to get (-5-5x)/(4x+3).
Answer: We have an odd number of pennies.
Step-by-step explanation:
So we have N pennies.
When we wan to divide the N pennies into groups of 2, we have a penny left over.
This means that N is not divisible by 2.
The problem is that there are infinite natural numbers that are not divisible by two, this is the set of odd numbers.
And remember that an odd number can be written as:
N = 2*k + 1.
where k is an integer.
Then we want to divide this by 2 (divide N into groups of 2)
we have:
N/2 = (2*k + 1)/2 = 2*k/2 + 1/2 = k + 1/2.
So we have k groups of 2 pennies, and a penny leftover that we can not divide into two.
