What is the value of x? 3/5x – 1/3 x = x – 1

1 answer:

6 0

The first step to solving this is to multiply both sides of the equation by 15.
9x - 5x = 15x - 15
Collect all of the like terms on the left side of the equals sign.
4x = 15x - 15
Move the variable to the left side of the equation and change its sign.
4x - 15x = -15
Now collect the like terms on the left side of the equation for the second time.
-11x = -15
Lastly,, divide both sides of the equation by -11 to get your final answer.
$\frac{15}{11}$
This means that the correct answer to your question is $\frac{15}{11}$ ,, or 1 $\frac{4}{11}$ simplified.
Let me know if you have any further questions

Charles is reading about computers. He learns that a computer processor can perform one command in approximately 0.000000016

ella [17]

The number 0.000000016 is expressed in scientific notation is:

$1.6 \times 10^{-8}$

Solution:

Given that,

Charlie learns that a computer processor can perform one command in approximately 0.000000016 nanoseconds

We have to express in scientific notation

Step 1:

Given number is:

0.000000016

Move the decimal point in 0.000000016 until there is only one non-zero digit to the left of the decimal point

Here,

Move the decimal 8 places to the right to get 1.6

We have moved the decimal to left, therefore, exponent is negative

$1.6 \times 10^{-8}$

Thus the given number is expressed in scientific notation

What is the value of the expression when n = 3?

inysia [295]

The value of expression when n = 3 is 22

Solution:

Given expression is:

$\frac{6(n^2 + 2)}{n}$

We have to find the value of expression when n = 3

Substitute n = 3 in given expression

$\rightarrow \frac{6(3^2 + 2)}{3}\\\\Simplify\ the\ above\ expression\\\\\rightarrow \frac{6(9+2)}{3}\\\\Solve\ the\ terms\ inside\ the\ bracket\\\\\rightarrow \frac{6(11)}{3}\\\\Divide\ 6\ by\ 3 \\\\\rightarrow 2 \times 11 = 22$

Thus the value of expression when n = 3 is 22

Using figure 3 at the right, AB II CD and t is not perpendicular to them, which pair of angles are not congruent?

coldgirl [10]

Answer:

∠5 = 95°

Step-by-step explanation:

Where the transversal crosses parallel lines at some angle not a right angle, all of the acute angles are congruent, and all of the obtuse angles are congruent. The acute angles are (obviously) not congruent with the acute angles. Any acute angle is supplementary to any obtuse angle.

Since angles 5 and 6 are a linear pair, the angle relationships of the parallel lines are irrelevant. A linear pair of angles is supplementary.

∠6 = 85° . . . . is given

∠5 is shown as obtuse, so its measure is ...

∠5 = 180° -85° = 95°

_____

Additional comment

85° angles: 2, 3, 6, 7

95° angles: 1, 4, 5, 8

Any angle from the 85° angle list is not congruent with any angle from the 95° angle list. For example, angles 2 and 5 are not congruent.
