ANSWER
EXPLANATION
The quadratic equation is:
Group variable terms:
Add the square of half, the coefficient of y to both sides.
The LHS us now a perfect square trinomial:
Take square root:
The first choice is correct.
Given Data:
The sides of the rectangle are 23 m, 23 m ,19 m and 19 m.
The length of the rectangle is 23 m.
Thus, option (B) is the correct option.
-(-(-)(-)(-10x)) = -5
We need to cancel out the negatives, so we need to simplify this.
To make things a bit easier for you, we can begin by counting out how many negatives we have. After counting, you should have a negative number count of 5. However, one of the negatives is apart of (-10x) so we'll have 4 negatives and then an extra negative in with 10x.
Remember that "-" could also be looked at as "-1."
So, if we break this down into smaller parts and substitute "-" into "-1," then this'll look like this :
-1 × -1 × -1 × -1 × (-10x) = -5
Remember that a negative times a negative is always a positive.
So, since there are four negatives, then you just multiply it all together.
This results in 1 × (-10x) = -5
Simplify.
-10x = -5
Now, you simply divide both sides by -10.
-10x ÷ -10 = -5 ÷ -10
Simplify.
x = 1/2

60 minutes per hour
1 1/2 hours = 60 x 1.5 = 90 minutes
90-25 = 65 minutes more
Answer:
88 adult tickets and 77 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be 8x and the number of student tickets sold be 7x.
adult tickets + student tickets = 165 tickets
8x + 7x = 165
15x = 165
x = 165 ÷ 15
= 11
No. of adult tickets sold (8x) = 11 × 8
= 88
No. of student tickets sold (7x) = 11 × 7
= 77
