Answer:
6
Step 1: Solve Square Root
Vx+3=x-3
x+3=(x-3)^2 (squared both sides)
x+3=x^2-6x+9
x+3-(x^2-6x+9)=0
(-x+1)(x-6)=0 (factor left side of equation)
-x+1=0 or x-6=0
x=1 or x=6
When you plug it in to check
1 (Doesn't Work)
6 (Work)
Therefore, 6 is your solution.
Answer:
c. 0.75
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have the following sample space
That is, the possible outcomes.
I am going to call boys b and girls g
b - b - b
b - b - g
b - g - b
b - g - g
g - b - b
g - b - g
g - g - b
g - g - g
Total outcomes:
8 outcomes
What is the probability that they will have at least one boy and at least one girl?
Desired outcomes:
At least one boy and at least one girl
b - b - g
b - g - b
b - g - g
g - b - b
g - b - g
g - g - b
Six desired outcomes.
Probability
The correct answer is:
c. 0.75
It is really simple. The ratio between both the triangles is 7, so you just divide 49 by 7(it gives you 7) to get the value of x. The answer is option (a) 7.

Answer: About 22.73 days.
Step-by-step explanation: Each person throws away about 4.4 pounds of trash daily. So the way to calculate this is to divide 100 pounds by 4.4 to find out how many days it would take for a person to throw away 10 pounds of trash.
Answer:
$637.5
Step-by-step explanation:
Given data
Cost of merchandise= $750
Discount= 15%
Let us find the amount of the discount
=15/100*750
=0.15*750
=$112.5
Hence the amount paid will be
=750-112.5
=$637.5
