I have this math question and im confused23=x-9;x=14
?
23=__-9
?
23=__

can you help me?

Answers

Answer 1
Answer: You are supposed to replace x with what we know and solve.
Answer 2
Answer: The answers would be 14 for the first and 23 for the second.

To solve, substitute the value of x, 14, into the equation then solve. However, I believe that you meant to make the - sign a + sign because that's the only way the statement would be true.

23 = x + 9 ; x=14
23 = 14 + 9
23 = 23

Show your work 25.04×3.005

Answers

Answer:

25.04\,* \,3.005=75.24520

Step-by-step explanation:

Multiplication refers to repeated addition of same number .

For example 2 * 3 means 3 is added 2 times or we can say 2 is added 3 times .

Here, we need to find product of 25.04 and 3.005 .

To solve : 25.04\,* \,3.005

First, we will solve 2504* 3005

2505* 3005=7524520

Now number 25.04 has 2 decimal places and 3.005 has 3 decimal places, so  will shift decimal  2 + 3 = 5 places towards left of number 7524520 .

So, 25.04\,* \,3.005=75.24520

    
      25.04
      3.005
 x   ----------
       12520
   7512000
+ --------------
  75.24520

What is 5/12 minus 3/20

Answers

(5)/(12) - (3)/(20)

First, find the LCD of the two fractions.
Multiples of 12: 12, 24, 36, 48, 60.
Multiples of 20: 20, 40, 60
The LCD is 60.
Second, change the denominators to be the same as the LCD.
(5x5)/(12x5) - (3x3)/(20x3)
Third, 5 × 5 = 25 / 12 × 5 = 60 / 3 × 3 = 9 / 20 × 3 = 60
(25)/(60) - (9)/(60)
Fourth, combine the denominators.
(25-9)/(60)
Fifth, subtract 25 - 9 to get 16.
(16)/(60)
Sixth, find the GCF of 16 and 60.
The GCF is 4.
Seventh, divide the numerator by the GCF.
16 ÷ 4 = 4
Eighth, divide the denominator by the GCF.
60 ÷ 4 = 15
Ninth, rewrite the fraction in simplest form.
(4)/(15)

Answer as fraction: (4)/(15)
Answer as decimal: 0.2667

Why would i need to use square roots and cube roots?

Answers

Answer:

We need the use of square root because it helps us to find the square root of a number, you want to find some number that when multiplied by itself gives you the original number.

or In other words, you can find the square root of 36, you want to find the number that when multiplied by itself gives you 36.

therefore, the square root of 36 is 6 [as 6 * 6 =36 ]

Also, the symbol for square root is √(x).

We need the use of cube root, to find the cube root of a number, you want to find some number that when multiplied by itself twice gives you the original number.

or in other word,  you can find the cube root of 64, you want to find the number that when multiplied by itself twice gives you 64.

therefore, the cube root of 64 is 4.  { as 4 * 4 * 4 = 64 }

The symbol of cube root is denoted as\sqrt[3]{x}
