Help Me5k = 6k + 4 - 6
vagabundo [1.1K]

Answer:

k = 2

Step-by-step explanation:

5k = 6k + 4 - 6

We can simplify this by solving 4 - 6 (replacing it with -2 !)

5k = 6k - 2

Now we can subtract 5k from both sides.

0 = k - 2

Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.

2 = k

Just reversing it...

k = 2

Answer: k = 2

Billy's age is twice Joe's age and the sum of their ages is 45. How old is Billy?
Fed [463]

Answer:

30 years old

Step-by-step explanation:

Joe's age can be set to x. Since Billy is twice as old as Joe, his age can be set to 2x. They add up to 45. You can set up an equation, 2x+x=45.

Simplify the equation.

3x=45, x=15

Joe is 15. Billy is 2(15)=30.

The sum of positive integers b and h is 34. If their difference is 8, what is the value of bh
kherson [118]
B + h = 34
b - h = 8 then b = h + 8

h + 8 + h = 34
2h + 8 = 34
2h = 34 - 8
2h = 26
h = 26/2
h = 13

b = h + 8
b = 13 + 8 = 21

Proof:
21 + 13 = 34
21 - 13 = 8

Value of bh = 21 * 8 = 168
