Answer:

x = 23

Step-by-step explanation:

simplify both sides of the equation then isolate the variable.

Answer:

x = 23

Step-by-step explanation:

x/20 + 20 ( -2/5 )/20 = 3/4

combine fractions with common denominator

x - 8/20 = 3/4

Multiply all terms by the same value to eliminate fraction denominators

20 . x - 8/20 = 3/4 = 20. 3/4

Cancel multiplied terms that are in the denominator

x - 8 = 20 . 3/4

Multiply the numbers

x - 8 = 15

Add 8 to both sides of the equation

x - 8 + 8 = 15 + 8

simplify

add the numbers

x = 23

Answer:

11

Step-by-step explanation:

You can plug it inot a calculator, or can make a factor tree, in which the 2 factors would be 11, so 11^2=121 and [tex]\sqrt121[/tex]=11

Answer:

11

Step-by-step explanation:

its something you basically have to just memorize and know... i dont know how to explain it, but like basically not all numbers have an even number square root. to have an even number for a square root, the number has to be able to be divided by the same 2 numbers. like 121, for it to have a whole number square root, it has to be able to be divided by 2 same numbers. or doubles... 11 times 11

11 squared is 121

square root of 121 is 11

We are given three vectors each one has its own coordinates. We need to be careful when we multiply two vectors.

For example, b × c = (b1,b2,b3)×(c1,c2,c3) = (b1c1,b2c2,b3c3)

Finally a×(b×c) = (a1b1c1,a2b2c2,a3b3c3)

Answer:

  P(E') = 12/13

Step-by-step explanation:

If E is the event "a 10 is drawn", then its probability is 4/52 = 1/13, because there are 4 cards in the deck that are 10s. The probability of E' is the complement of this:

  P(E') = 1 -P(E) = 1 -1/13

  P(E') = 12/13

[tex]\sf \Large \boxed{\displaystyle \sf \frac{12}{13} } \\\\\\ 10 \ of \ spades \ or\ 10 \ of \ clubs \ or\ 10 \ of \ diamonds \ or\ 10 \ of \ hearts \\\\4 \ cards \ from \ the \ 52 \ are \ tens\\\\48 \ are \ not \ tens\\\\\displaystyle \frac{48}{52} =\frac{12}{13}[/tex]

Answer: 4x+1 3/4=10

Step-by-step explanation: Took the test. Plus you can check to see if it equals to - 10 = 10 by replacing x with 2 1/16. Example: 4 * 2 1/16 + 1 3/4 =10. So 10 = 10 is a true match.

The given case can be represented as the equation 4x + 13/4 = 10.

A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.

Given that,

The length of board = 10 feet.

The length of piece that is cut first = 13/4 feet.

Suppose the length of each remaining piece cut into four equal parts is x feet.

Now, the expression for the total length of the board can be given as the sum of the total length of the remaining piece and the the piece that is cut first.

In mathematical form it can be written as,

4x + 13/4 = 10

Hence, the equation for the given case is 4x + 13/4 = 10.

Step-by-step explanation:

For this problem you need to find 3/4 of 18. 18x3/4 = 54/4, or 13.5

The total number of miles Steve's family traveled is 24 miles.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Steve's family traveled 3/4 the distance that Mike's family traveled.

Let the total number of miles Steve's family traveled be x.

Now, 3/4 ×x=18

3x=72

x=72/3

x=24 miles

Therefore, the total number of miles Steve's family traveled is 24 miles.

Answer:

x = -2,4

(disclaimer plugging in -2 will give an imaginary number)

Step-by-step explanation:

3[tex]\sqrt{x^2-7}[/tex]=3[tex]\sqrt{2x+1}[/tex]

Divide both sides by 3

[tex]\sqrt{x^2-7}[/tex]=[tex]\sqrt{2x+1}[/tex]

Square both sides to cancel square roots

[tex]x^2-7=2x+1[/tex]

Move all the terms to the left side

[tex]x^2-2x-8=0[/tex]

Use the quadratic formula

[tex]x=\frac{2 +/- \sqrt{(-2)^2-4(1)(-8)}}{2(1)}[/tex]

which gives x= -2,4

OR factor the quadratic

(x-4)(x+2)=0

x= -2,4

The solution of the equation 3 sqrt x^2-7= 3 sqrt 2x+1 is,  x = -2,4

(disclaimer plugging in -2 will give an imaginary number)

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

3√x²-7=3√2x+1

Divide both sides by 3

√x²-7=√2x+1

Square both sides to cancel square roots

x²-7=2x+1

Move all the terms to the left side

x^2-2x-8=0

Use the quadratic formula

x=2±√2-4(-8)/2

solving we get,

which gives x= -2,4

OR factor the quadratic

(x-4)(x+2)=0

x= -2,4
