Amanda needs to cut a board to use for a project. The board is 10 feet long. She first has to cut off 1 3/4 feet from one end of the board. She then cuts the remaining section of board into 4 equal pieces.

1 3/4x−4=10

1 3/4x+4=10

4x−1 3/4=10

4x+1 3/4=10

Answers

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.

What is a system of linear equations?

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.

Basically the first image goes in the first box because opposites attract and the second image is what happens when you let the magnets go. The third image would go into the second chart because same-sides repel each other and the fourth picture shows what happens if you let the magnets that have the same sides facing each other go.

b= (b1, b2,b3)
c=( c1, c2, c3) )
solve : a×(b×c)​

Answers

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)

Answers

Answer:

Four over nine looks like 4/9 and 2 over nine looks like 2/9.

Since they have the same denominator, which is 9, 4/9 would be bigger than 2/9, because 4 is bigger than 2.

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

x/20 - 2/5 = 3/4

Plz help :)

Answers

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
