Answer:

(E) 45

Step-by-step explanation:

                \frac{s}{t} = 64.12

From the question, s and t are positive integers.

                          s = 64.12t

From the division of s/t which gives 64.12, 0.12 it the remainder.

Now, split 64.12 into its integral multiple.

                         s =   (64 + 0.12)t

                         s =   64t + 0.12t

The value that could be the remainder would be any of the values given in the options that will give positive integer when it equals 0.12t.

Let's test for the answer

(A) 0.12t = 2

           t  = 16.77  Not an integer

(B)   0.12t = 4

          t  = 33.33  Not an integer

(C)   0.12t = 8

          t  = 66.67  Not an integer

(D)   0.12t = 20

          t  = 166.67  Not an integer

(B)   0.12t = 45

          t  = 375   An Integer   (CORRECT ANSWER)

2. Four less than six times a number is 32. Write and solve an equation.
zhenek [66]

Answer:

6x - 4 = 32. The variable (times a number) is equal to 6.

Step-by-step explanation:

So this equation is basically asking you to formulate an equation using only the words given. For this equation, let's use a variable in place of the part where it says "times a number." When a question says that phrase, that means that they are telling you to use a variable in place of a mystery number. A variable is a letter in place of a mystery number. Knowing this, let's now solve the equation. We will use the variable x in place of our mystery number.

Four less than 6 times a number: 6x - 4 _ __.

Now we can add the equal sign and the 32: 6x - 4 = 32.

We can now solve. Add 4 to both sides of the equation to cancel out the -4:

6x - 4 = 32

    <u>+4   + 4</u>

6x  =    36

Now we divide 6 into both sides of the equation to single out the x.

<u>6x = 36</u>

6      6

36/6 = 6, so:

x = 6

I hope that this helps.
