We let x = Kim's amount
y = Laura's amount
z = Molly's amount
We have three unknowns and it should be that we have three equations to set up to be able to solve this.
x + y + z = 385 (1)
z - x = 105 (2)
2/5 = x/z (3)
Solving simultaneously, we can get the values as follows:
x = 70
z = 175
y = 140
Therefore, the percentage that Laura got was 36.4% of the whole money. Hope this answers the question.
Answer:
C: 152
Step-by-step explanation:
All of the numbers that are listed in or close to the 300's so if you added a 152 it would be very different from the other numbers. Therefore making 152 an outlier.
C: 152
Answer:
-3, - 2, - 1, 0, 1, 2, 3, 4
Step-by-step explanation:
The blue line of the number line can have its inequality range written as :
Since both startibg and endpoints are shaded :
-1 ≤ x ≤ 4
The red line can also be written as :
Only the start is shaded:
-3 ≤ x < 2
Listing out the values :
Blue line :-1 ≤ x ≤ 4
-1, 0, 1, 2, 3, 4
The red line : -3 ≤ x < 2
-3, - 2, - 1, 0, 1, 2
Combining both values :
-3, - 2, - 1, 0, 1, 2, 3, 4
Answer:
A ) 17.6
Step-by-step explanation:
I'm probably wrong but I did
2.8 x 2 = 5.6
5.6 x 2 = 17.58400
Considering the area of a rectangle, the equation that could be used to determine the width for which the costs are the same is:
125 + 2(x² + 5x) = 75 + 2.5(x² + 5x)
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by the multiplication of dimensions, that is:
A = lw
In this problem, the dimensions are given as follows:
w = x, l = x + 5.
Hence the area in square feet is:
A = x(x + 5) = x² + 5x.
Then the costs are given as follows:
- B(x) = 75 + 2.5(x² + 5x).
The costs will be equal when:
A(x) = B(x)
125 + 2(x² + 5x) = 75 + 2.5(x² + 5x)
