If d is the midpoint of ce, ce=10x+18 and de=7x-1, find x

sashaice [31]

Given that D is the mid point of CE ,

So D will bisect CE, it means the length of DE and CD is equal.

=> DE + CD = CE

As DE and CD are equal,

=> DE + DE = CE

=> 2 DE = CE

Putting values from the question,

=> 2( 7x - 1 ) = 10x + 18

=> 14x - 2 = 10x + 18

=> 14x - 10x = 18 + 2

=> 4x = 20

=> x = 20 / 4

=> x = 10 / 2

=> x = 5

$.$

Therefore, the value of x is 5

Jon bought a printer for $189 and a set of printer cartridges for $192. Sales tax on these items was 6.5%. What is Jon's total b

julia-pushkina [17]

So first we need to find the total before tax. Let's add up the two prices:

$189+192=381$

So we know that the total before tax is $381. Now we are told that the sales tax on these items is 6.5%. It would be easier for us to convert 6.5% to a decimal in order to multiply. Let's convert 6.5% to a decimal by dividing by 100:

$\frac{6.5}{100}=0.065$

Now that we have the sales tax in decimal form, let's multiply this sales tax by the total amount of the items before tax ($381):

$381*0.065=24.77$

This means that $24.77 is the tax for this purchase. To find the total amount that Jon paid for these items after tax, you must add the tax to the total amount before tax to give you:

$381+24.77=405.77$

So now we know that Jon's total bill for these items is $405.77.

The probability of the given condition is 28/165.

Given that, there are four boys and eight girls in a class.

We need to find the probability of the given question.

<h3>What is probability?</h3>

The probability is defined as the chances of happening of any random event or the possibility of happening of any event is called the probability.

The teacher randomly selects three different students to answer questions.

The first is the student is a girl, the second student is a boy, and the third student is a girl.

The total number of students=12, the number of boys=4 and the number of girls=8.

Now,

Step 1: The first student is a girl=8/12

Step 2: The second student is a boy=4/11

Step 3: The third student is a girl=7/10

In the first step, you select one of 8 girls among 12 students.

In the second step, you select one of 4 boys among the remaining 11 students.

In the third step, you select one of the remaining 7 girls among the remaining 10 students.

Thus, probability=(8/12)×(4/11)×(7/10)=28/165

Therefore, the probability of the given condition is 28/165.
