1.50 x 7 = 10.5
0.85 x 5 = 4.25
10.5 + 4.25 = 14.75
So you can only have 7 roses . I found this out using trial and error and then adding on the correct number of carnations to make it a dozen and to make sure it equaled 14.75 .
Hope this all makes sense .
Answer:
One solution
Step-by-step explanation:
Answer: B. |x-100| = 25
Explanation:
Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.
The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
All 4 are right triangle congruence theorems.
we have
we know that
The area of a rectangle is equal to
where
L is the length side of the rectangle
W is the width side of the rectangle
In this problem
Equate the area to zero and Find the roots of the quadratic equation
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
Square root both sides
so
therefore
<u>the answer is the option</u>
