Answer---&gt;x/3<br>Process?​
Komok [63]

Step-by-step explanation:

2x/3 - x/3 = x/3

they both have the same denominators (number at the bottom of the fraction) so all you have to do it subtract the numerators (top of the fraction) together. 2x-x =x, that's why it's x on the numerator for the answer

hope this helps

Help me pls guys/girls
Kamila [148]

Answer:

 V = 9.828 * 10^7 mm^3

a= 9.828  b = 7

9,827,000  mm^3

Step-by-step explanation:

The volume of a rectangular prism is

V = l*w*h

V = 1.2 *10^3  * 3.9*10^2  * 2.1*10^2

We multiply the numbers out front and add the exponents  (the powers of 10)

V = (1.2*3.9*2.1)  * 10^(3+2+2)

 V = 9.828 * 10^7 mm^3

Rewriting this in standard form means moving the decimal 7 places to the left.  Since there is not enough places add zeros

9,827,000  mm^3
