What is the value of x + 3/4 when x=1/8

7/8

Step-by-step explanation: This is a substitution problem, from the expression x + ³/₄, where x = ¹/₈, we now replace or substitute for x and then solve the expression fractionally, the expression now becomes

¹/₈ + ³/₄

Now , find the l. c. m. of the denominator 8 and 4

            1 + 6

        =      

              8

          = 7/8

NOTE: To get 1 and 6, you find out how many times 8 can go in the l. c. m. and later multiplied the number of times by  the numerator which = 1.

And the number of times 4 can go in the l. c. m. (8) which is 2 times then multiplied by the numerator (3) = 6.

Adding 1 and 6 together gives 7/8.

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
