Total divided by number of rows=number per row
63/7=9
9 per row
The true statement about the inequality is that Total sales per day is greater than $250
<h3>How to write and solve inequality equation?</h3>
- Amount earned per day = 25 + 5% of x
= 25 + 0.05x
- Thursday = 4th day of the week
The inequality:
4(25 + 0.05x) > 50
100 + 0.2x > 50
100 - 50 > 0.2x
50 > 0.2x
x > 50/0.2
x > $250

Since 30 lights are 40% of them:
30*2= 60
Since 2*40= 80
We still need the 20 percent.
Half of 40= 20.
30/2= 15
So, 15+60= 75
75 is the number of lights on the tree.
I hope this helps!

Answer:
A sqrt(x+2) - sqrt(x)
Step-by-step explanation:
2
--------------
sqrt(x) + sqrt(x+2)
Multiply top and bottom by sqrt(x) - sqrt(x+2)
2 sqrt(x) - sqrt(x+2)
------------------------ * --------------------------
sqrt(x) + sqrt(x+2) sqrt(x) - sqrt(x+2)
FOIL the denominator
2 (sqrt(x) - sqrt(x+2))
------------------------------
sqrt(x^2) - sqrt(x) sqrt(x+2) + sqrt(x) sqrt(x+2) - sqrt(x+2)^2
2 sqrt(x) - 2 sqrt(x+2)
------------------------------
x - (x+2)
Distribute the minus sign
2 (sqrt(x) - sqrt(x+2))
------------------------------
x - x-2
2 (sqrt(x) - sqrt(x+2))
------------------------------
-2
Cancel the 2 in the top and bottom
(sqrt(x) - sqrt(x+2))
------------------------------
-1
Distribute the -1
sqrt(x+2) - sqrt(x)
