This number is written in extended form. Each multiplication determines the place the digit is in the number you have to determine.

4*100 → This indicates that the first digit of the number is in the place of the "hundreds", if you solve the multiplication the result is 400

2*10 → This multiplication indicates that the second digit of the number is in the place of the "tens", the result of the multiplication is 20

4*1 → This multiplication indicartes that the third digit of the number represents the "units", te result of the multiplication is 4

After the units you have to put the decimal point and all digits below it will be decimal values.

7*(1/10) → The first digit after the decimal point is in the "tenths" place, you can write it as 0.7

7*(1/100) → This indicates that this digit is in the second place after the decimal dot, in the "hundredths" place, you can write it as 0.07

0*(1/1000)→ The multiplication indicates that the digit is in the third place after the decimal dot, in the "thousands" place, you can write it as 0.000

To write the number in decimal form you have to put each digit in their given order, or add the result of each multiplicatin toghether:

400+20+4+0.7+0.07+0.000

424.770

Factor completely<br><br> 2x^2+7x+5
jeka94

Answer:

(2x+5)(x+1)

Step-by-step explanation:

We look for two numbers which multiply to 10(that is 2×5) and add to 7. Our numbers are 2and 5

2×5=10 and 2+5=7

Therefore we have

(2x²+2x)+(5x+5)

2x(x+1)+5(x+1)

(2x+5)(x+1)

Josiah ran 4/5 mile. How many tenths are equal to 4/5 mile.
kati45 [8]
<span>Josiah ran 4/5 miles. We need to find the tenths that is present to the given number which is 4/5.
4/5 is a fraction, and since we are looking for tenths which is a decimal value. Thus, we need to convert this fraction to decimals.
To convert, simply divide the numerator by the denominator.
In the given number, 4 is our numerator and 5 is our denominator.
=> 4 / 5
=> 0.8
Therefore, 8 is the value of tenths because it is the number next to the decimal point.

How do you solve this two step equation? 5 -2/3x =3​
podryga [215]

Answer:

x = 3

Step-by-step explanation:

I will assume you meant 5 - (2/3)x = 3.  This simplifies to -(2/3)x = -2, or

(1/3)x = 1, so that x = 3.

                                                         2

"2/3x" could be interpreted as   ---------  which would give us a very different

                                                         3x                 result.  Use parentheses to

                                                                               lessen the chances of

                                                                                misinterpretation.
