A, B, and C are 3 collinear point. (3 points on the same line.)

AB=3y-1, and BC=7y

Since A, B, and C then AC = AB+BC = (3y-1)+7y = 10y-1

AC is 29 units, so we write the equation:

(AC=) 10y-1 =29

adding 1 to both sides, we have:
          
               10y=30, 

dividing both sides by 10:
 
                    y=3.

AB = 3y-1, substituting y with 3, we have AB=3*3-1=9-1=8

What is the value of the variable in the equation, r-17=22 *
aleksklad [387]

Answer:

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7,  or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

Answer: x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

The number of pages printed before replacing the cartridge in a laser printer is normally distributed to a mean of 11,500 pages
Helen [10]
<span>a. What is the probability that the printer produces more than 12,000 pages before this cartridge must be replaced? 
solution
to solve the equation we need to find the z-score:
z=(x-</span>μ)/σ
where:
x=12000
μ=mean=11500
σ=standard deviation=800
thus
z=(12000-11500)/800=0.625
thus
P(x>12000)=1-P(x<12000)=1-0.7357=0.2643

<span>b. What is the probability that the printer produces fewer than 10,000 pages?
z=(10000-11500)/800
z=-1.875
hence
P(x<10000)
=0.0301
