1. Solve 3x + 3 =21
sveta [45]
1.

3x + 3 = 21

3x = 21-3

3x = 18

x = 18/3

Therefore,
x = 6


So option ( B) is the correct one.


2.

\frac{3x}{2}  - 4 = 16 \\  \frac{3x}{2}  = 16 + 4 \\  \\  \frac{3x}{2}  = 20  \\ 3x = 20 \times 2 \\ 3x = 40 \\ x =  \frac{40}{3}  = 13 \frac{1}{3}


Therefore option (B) is the correct one here too.

Karl’s and eddie’s ages added together are equal to 65. 10 years ago, Karl was twice as old as Eddie. How old are they now
trapecia [35]

9514 1404 393

Answer:

  • Karl is 40
  • Eddie is 25

Step-by-step explanation:

10 years ago, the sum of their ages was 65 -2·10 = 45.

If Karl was twice as old as Eddie, his contribution was 2/3 of the sum and Eddie's was 1/3. That is, Karl was (2/3)(45) = 30 and Eddie was 15 at that time.

Now, Karl is 40 and Eddie is 25.

__

This can be solved using a system of equations.

  e = 65 -k

  (k -10) = 2(e -10)

Substituting the first equation into the second gives ...

  k -10 = 2((65 -k) -10)

  k -10 = 110 -2k . . . . . . . simplify

  3k = 120 . . . . . . . . . . . . add 10+2k

  k = 40

  e = 65 -40 = 25
