Answer 1
Answer:

x in terms of b:

-2(bx - 5) = 16

-2bx + 10 = 16

-2bx =  6

    x = 6 / -2b

    x = -3/b

--------------------------------

when b = 3 then

-2(3x - 5) = 16

-6x + 10 = 16

-6x =  6

  x = -1

Answer

The value of x in terms of b is -3/b

The value of x when b is 3 is -1

Nine tenths of a sum of money is 45. Find the whole amount

Answers

If you would like to know the whole amount of money, you can calculate this using the following steps:

nine tenths of a sum of money is 45
9/10 * x = 45     /*10
9 * x = 45 * 10   /9
x = 45 * 10 / 9
x = 50

Result: Nine tenths of 50 is 45.
The answer is 50.

First do 45 divided by 9 which is 5 then times by 10 results in 50.

A way to check this is by then finding 1/10 of 50 which is 5 then X by 9 is 45, which is what you originally started with.

In the diagram below, DE and Ef are tangent to o. Which expression gives
the measure of DEF?

Answers

The expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.

What is the theorem of two tangents from external point?

When the two tangent are drawn to a circle from an exterior point then according to this theorem-

The length of these two tangents is equal.

  • Both the tangents subtend equal angle at the center of the circle.
  • The angle between the two tangent is bisect by the line joining to the exterior point and the center.

In the diagram below, DE and EF are tangent to o.  In the diagram half of the difference of the arc GF and DF is equal to the angle of the measure of DEF. Thus,

\angle DE F=(1)/(2)(GF-DF)\n\angle DE F=(1)/(2)(236-124)

Thus, the expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.

Answer:

A

Step-by-step explanation:

∠DEF is a tangent- tangent angle and is measured as

∠DEF = (1)/(2)( arc GF - arc DF), that is

∠DEF = (1)/(2)(236 - 124)° → A

Which number is not a composite number 2 9 15 21

Number which is not a composite number is given by the equation A = 2

What are Factors of a Number?

Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the set of number be in set C = { 2 , 9 , 15 , 21 }

And , composite number is a positive integer that can be formed by multiplying two smaller positive integers

So , the factors of 9 = 1 , 3 , 9

The factors of 15 = 1 , 3 , 5 , 15

The factors of 21 = 1 , 3 , 7 , 21

And , the factors of 2 are 1 and the number 2 itself

Therefore , the value of A = 2

Hence , the number 2 is a composite number

is not a composite number but it is actually a prime number because it is only divisible by one and itself and only composite numbers have more than just 2 factors so since 2 only has 2 factors, it is a prime number.
