You would multiply the # of pounds (5) by the price ($1.99). So, 5 x 1.99 = $9.95.
Answer:
x = (-1/4)(1 ± √33)
Step-by-step explanation:
Let's "complete the square."
This procedure requires taking half of the coefficient of x and squaring it:
Half of 1/2 is 1/4, and the square of 1/4 is 1/16.
Then we have:
x^2 + (1/2)x + 1/16 = 2 + 1/16 = 33/16
Rewriting x^2 + (1/2)x + 1/16 as the square of a binomial, we get:
(x + 1/4)^2 = 33/16
We must solve this for x.
Taking the sqrt of both sides, we get:
x + 1/4 = ±√33/4, or:
x = -1/4 ±√33/4, or
x = (-1/4)(1 ± √33)
<span>The solution to the problem is as follows:
y = -15x^2 + 64x + 360
400 = -15x^2 + 64x + 360
-15x^2 + 64x - 40 = 0
sol ve this for x
x = 3.5

Answer:
x = 18.4
Step-by-step explanation:
x - 3.5 = 14.9
Add 3.5 to both sides.
x = 14.9 + 3.5
x = 18.4
Two fractions equivalent are 18/20 & 27/30
