9  1/3 days

Step-by-step explanation:

  • If the total change in the size of the pencil is -7/9 millimeters. Then the actual change itself is 7/9 which is a positive value.
  • If each day the pencil changes by 1/12 millimeters, how many 1/12 millimeters are there in 7/9 millimeters. This is a division query;

7/9  ÷ 1/12 = 7/9 * 12/1 = 28/3

= 9 & 1/3 days

Find the value of x.<br> (2x + 30)<br> (5x - 18)
laiz [17]

Answer:

No answer as written.  16 if we add an equals sign.

Step-by-step explanation:

As written, there is no "=" sign in either expression.  That means they are only expressions, not equations.  x can be anything.  10, 12345, 0.00000343345567788, etc.  There is nothing that restricts the value of x.

If we set the two expressions equal to each other, we can calculate a value of x:

(2x + 30) = (5x - 18)

3x = 48

x = 16
