The answer is b (I think not really sure)
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
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.
3 is the 10 billions place
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
