what does x equal in this equation

Answers

Answer 1

what’s the equation? i don’t see it?

Answer 2

Answer:

x=2

Step-by-step explanation:

You have to subtract 8 from both sides.

-5x+8=-2

-8 -8

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

-5x= -10

now divide both sides by -5.

x=-10/-5

(And two negatives make a positive.)

x=10/5

now you have to simplify 10/5

10/5 simplified is 2

so the answer is:

x=2

I hope this helps. :)

What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:

Step 1: You must divide the numerator of the fraction by the denominator of the fraction.

Step 2: Now you must add the quotient obtained to the Whole number part.

So, you get:

3 + 1/4

=3 + 0.25

= 3.25

Then, the scale image that maps "Figure a" onto "Figure b" is:

1: 3.25

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .

Therefore, you get that the result is:

x = 3 * 3.25

or, x = 9.75

Hence, The solution is : the value of x is x = 9.75.

Write 3/15 3/7 3/21 3/8 3/11 in ascending order

Answers

Answer:

The sorted inputs in order from least to greatest is:

3/21 < 3/15 < 3/11 < 3/8 < 3/7

Step-by-step explanation:

Using the given inputs:

3/15 3/7 3/21 3/8 3/11

As the least common denominator (LCD) is: 9240

Rewriting as equivalent fractions with the LCD:

3/15 3/7 3/21 3/8 3/11

1848/9240 3960/9240 1320/9240 3465/9240 2520/9240

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

3/21 3/15 3/11 3/8 3/7

1320/9240 < 1848/9240 < 2520/9240 < 3465/9240 < 3960/9240

Therefore, the sorted inputs in order from least to greatest is:

In a classroom of 30 students, in which 18 are girls and 12 are boys, what is the probability that two boys are selected without replacement by the teacher?

Answers

Answer:

about 4 out of 10

Step-by-step explanation:

Probabilities are used to determine the chances of events

The probability that two boys are selected is 0.1517

The given parameters are:

Boys = 12

Girls = 18

Total = 30

Given that the selection is without replacement, the probability that two boys are selected is:

p = 12/30 * 11/29

So, we have:

p = 0.1517

Hence, the probability that two boys are selected is 0.1517

Find side BC for the triangle shown (round to the nearest tenth).

Answers

Answer: 2.6 (rounded answer)

Step-by-step explanation: To solve for the side BC we can find the tangent (TAN) of 41 degrees. Since the tangent of an angle is equal to the opposite side over adjacent, we can set up an equation that looks like this, assigning side BC to be x:

tan(41)= x/16
