-12x + 14 = -6x - 4

Answer: 0.17 or not rounded, 0.17175572519.
Step-by-step explanation: 6 x 3 x 2.5 = 45, now we just need to divide 45 by 262, so 45/262 = 0.17175572519, or rounded, 0.17.

There are 100 people in a sport centre. 67 people use the gym. 62 people use the swimming pool. 56 people use the track. 38 people use the gym and the pool. 31 people use the pool and the track. 33 people use the gym and the track. 16 people use all three facilities. A person is selected at random. What is the probability that this person uses at least 2 facilities?
Answer:
7/10
Step-by-step explanation:
For a person to use at least two of the facilities means they can use the three facilities as well.
Let n(U) be the total people in the sport centre = 100
n(G) be people that uses gym = 67
n(S) be people that uses swimming pool = 62
n(T) be people that uses track = 56
n(GnP) be gym and pool = 38
n(PnT) be people that use the pool and the track = 31
n(GnT) be people that use the gym and the track = 33
n(GnPnT) be people that use all three facilities = 16
People that uses gym and pool only = n(GnP) - n(GnPnT)
= 38-16
= 22
People that uses pool and track only = n(PnT) - n(GnPnT)
= 31-16
= 15
People that uses gym and track only = n(GnT) - n(GnPnT)
= 33-16
= 17
Total people that uses at least 2 facilities = 16+22+15+17 = 70
Probability that this person uses at least 2 facilities = Total people that uses at least 2 facilities/Total people in the sport centre
Probability that this person uses at least 2 facilities = 70/100 = 7/10

Point slope question
Answer: (y + 3) = -1/3 (x - 2)
Step-by-step explanation:
Point-slope form has the form of
y - y1 = m (x - x1)
Where
y1 is the y-value of a point on the line
x1 is the x-value of a point on the line
m is the slope of the line
The problem already gives a point on the line, (2, -3)
(y + 3) = m (x - 2)
Remember to put the opposite value of the x and y values. (In other words, do NOT write (y - 3) = m (x + 2) )
The slope of a perpendicular line is the opposite reciprocal of slope of the line it is perpendicular to. The perpendicular line given in the equation is
3x - y = 4
When rearranged to slope-intercept form, we get
y = 3x - 4
Meaning the slope of the perpendicular line is 3. The opposite reciprocal of positive three is negative one-third. Therefore, the slope of the line we are solving for is -1/3.

What is B equal to?
what is the solution to the equasion 1/2x + 3= 2/3x + 1
Answer:
12
Step-by-step explanation:
1/2x+2=2/3x
2= 2/3x-1/2x
2=4/6x-3/6x
2=1/6x
multiply both sides by 6
x=12
Answer: x = 12
Step-by-step explanation:
1/2x + 3= 2/3x + 1
= 1/2x + 3 - 3 = 2/3x +1 -3
Simplify
= 1/2x = 2/3x -2
= -1/6x = -2
multiply both sides by -6
(-1/6x)(-6) = (-2)(-6)
x = 12

Answer:
The first column would be (x,y)---> (x,-y)
The second column would be (x,y)---> (x+3, y-8)
The third column would be (x,y)----> (-x,-y)
Then the last column would be (x,y)---> (x-8, y-3)
A map of Colorado says that the scale is 1 inch to 20 miles or 1 to 1,267,200. Are these two ways of reporting the scale the same? Explain your reasoning.
Answer:
1,267,200
Step-by-step explanation:
Given that the map reported that the scale is 1 inch to 20 miles.
Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200
Therefore, the scale of 1 inch to 20 miles can also be represented as 1 to 1,267,200

A square has an area of 9yd^2. What is the length of each side?
Answer: The side length is 3 yards.
Step-by-step explanation:
To find the area of a square, you have to square one of it's side lengths since they all share the same length. Since we know the area, and we need to find the side length so we just need to find the square root of the area.
[tex]\sqrt{9}[/tex] = 3
The side length is 3 yards.
The length of each side of a square is, 3 yards.
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
⇒ An area of square = 9 yards²
Now, We know that;
⇒ Area of square = Side²
Let the side of square = a
So, We get;
⇒ a² = 9
⇒ a = √ 9
⇒ a = 3 yards

You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached your market. You anticipate a busy weekend and would like to have 100 pounds of peaches to sell. To have 100 pounds of peaches and considering the spoilage rate, how many pounds should you order?
Answer:
110 pounds of peaches should be ordered
Step-by-step explanation:
Here, we want to calculate the number of pounds of peaches to order.
Let the number of peaches to ordered be x peaches
Now, since 9% is expected to be bad, then the percentage expected to be good will be 91%
Thus;
91% of x = 100
91/100 * x = 100
91x = 100 * 100
x = 10000/91
x = 109.89
Since we cannot have fractional peaches, then x must be 110

Prove that if -5(x + 4) = 70, the x = -18. Write a justification for each step.
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(x+4)=70
Step 1: Simplify both sides of the equation.
−5(x+4)=70
(−5)(x)+(−5)(4)=70(Distribute)
−5x+−20=70
−5x−20=70
Step 2: Add 20 to both sides.
−5x−20+20=70+20
−5x=90
Step 3: Divide both sides by -5.
