If the gray suitcase weighs 11 lb more than the pink suitcase, the pink suitcase weighs 5 lb than the blue suitcase, and the total of 3 suitcases is 127 lb, then the blue suitcase weighs 35.3 lb
Let the gray suitcase be represented by g
Let the pink suitcase be represented by p
Let the blue suitcase be represented by b
The gray suitcase weighs 11 lb more than the pink suitcase
g = p + 11........(1)
The pink suitcase weighs 5 lb than the blue suitcase.
p = b + 5
b = p - 5...........(2)
Total of 3 suitcases = 127 lb
p + b + g = 127............(3)
Substitute equations (1) and (2) into equation (3)
p + p - 5 + p + 11 = 127
3p + 6 = 127
3p = 127 - 6
3p = 121
p = 121/3
p = 40.3 lb
Substitute p = 40.3 into equation (2)
b = p - 5
b = 40.3 - 5
b = 35.3
The blue suitcase weigh 35.3 lb

3)Calcular la distancia entre los puntos A = (2,1) y B =(-3,2)
Answer:
Step-by-step explanation:
You use the distance formula
d = √ (x1-x2) ² + (y1- y2) ²
d = √ (2 - (-3)) ² + (1 - 2) ²
d = √ (25 + 1)
d = √26
d = 5.2
Find the value of x that makes m ∥ n.
Answer:
x = 60Step-by-step explanation:
Corresponding angles must be same to make the lines m and n parallel.
2x + 15 = 1352x = 120x = 60Answer:
x = 60
Step-by-step explanation:
1. First of all, we must know that these angles are corresponding. That means they're congruent in angle measures.
2. Given the information above, 2x + 15 = 135.
3. (Solving)
Step 1: Subtract 15 from both sides.
[tex]2x + 15 - 15 = 135 - 15[/tex] [tex]2x = 120[/tex]Step 2: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{120}{2}[/tex] [tex]x = 60[/tex]Step 3: Check if solution is correct.
[tex]2(60)+15=135[/tex] [tex]120 + 15 = 135[/tex] [tex]135 = 135[/tex]Therefore, x = 60.

For the equation
y + 2 = 6(x - 5),
the line has a slope of 6 and contains what point?
Answer:
(5, -2)
Step-by-step explanation:
1. The equation "y + 2 = 6(x - 5)" is in the form of point-slope. Point slope form is [tex]y-y_1=m(x-x_1)[/tex] where y_1 = y-coordinate of point, m = slope, and x_1 = x-coordinate of point.
2. Given the information above, the point (5, -2) and slope of 6 makes the equation y + 2 = 6(x - 5) because:
[tex]y - y_1 = m(x-x_1)[/tex] [tex]y - (-2) = 6(x-5)[/tex] [tex]y + 2=6x-5[/tex]Therefore, the point is (5,-2).

For Pool A, the water level is dropping 2.5 inches per hour. For Pool B, the water level increases 2.5 inches per hour. Starting water levels are shown. Pool A: 60 inches Pool B: 20 inches When will the pools have the same water level? Write an equation and solve. Enter the correct answers in the boxes. Equation: h=what. The pools will have the same water level after hours. Σ
Answer:
8 hours
Step-by-step explanation:
60 - 2.5x = 20 + 2.5x
40 = 5x
8 = x
60 - (2.5 x 8) = 40
20 + (2.5 x 8) = 40

If randomly guessing, the probability that a person can correctly guess your birthday (month and day) on the first try is 1365=0.0027. The probability that a person can correctly guess the birthday of two people in a row is (1365)2=0.0000075. You and a friend are out one night and you meet a magician who bets that she can randomly guess both of your birthdays on the first try.
QUESTION: If the magician does guess both of your birthdays, would you believe it was by pure chance, or would you believe that the magician knew your birthdays by some other means (whether that be magic, being a creepy stalker, etc.)? Explain.

This claim seems a bit fast and you want to put him to the test, so you make him run a mile. He runs the mile in 5.8 minutes, which is slower than his claim. However, if he is telling the truth, there is about a 0.31 probability, of having a time at least as high as 5.8 minutes.

What’s the domain and range of the exponential growth function?
Answer:
Recall that the domain of a function is the set of input or x -values for which the function is defined, while the range is the set of all the output or y -values that the function takes. A simple exponential function like f ( x) = 2 x has as its domain the whole real line.

Part A Question Create an equation from the model that describes the relationship between the weights on each side of the scale. Enter the correct answer in the box.
use the picture i included to solve
and please be quick
Answer:
steps below
Step-by-step explanation:
3+2y = 2+4y
2y = 1
y = 1/2
Is it correct?
Answer:
On the left side, there are two large weights of mass y and three small weights of mass 1. Represent this side with the expression 2y + 3.
On the right side, there are four large weights of mass y and two small weights of mass 1. Represent this side with the expression 4y + 2.
The scale is balanced, so there is equal weight on each side. We can describe the relationship between the weight on each side of the scale using the equation 2y + 3 = 4y + 2.
