Answer:
213
Step-by-step explanation:
if you multiply 44 weeks by 2 streetlights per week you get 88 streetlights which you then add to the lights you already have.
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i

Step-by-step explanation:
Answer:
Step-by-step explanation:
The given equation is
We group the linear terms to get:
We compare to
This means
a=1, b=-6 and c=-10
We plug in the values into the quadratic formula:
This gives us
The solutions are
or
Given:
Cost of one pound of apples = $1.98
To find:
The cost of 0.75 pound of apples.
Solution:
We have,
Cost of one pound = $1.98
So, cost of 0.75 pound of apples = 0.75 × cost of one pound of apples
Therefore, the cost of 0.75 pound of apples is $1.485.
