Answer:
about 5.2 years
Step-by-step explanation:
We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.

We develop an equation for the given situation by first writing the general equation for lines,
y = mx + b
Substituting to this given the values given above,
(1990) 430 = b
(2000) 400 = m(10) + 430
The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,
y = -3x + 430
Answer:
I believe it is: 6n+8+7y+4m
Step-by-step explanation:
You can't do anything about the numbers with variables afterwards, so you just list those and you just add and subtract the numbers without variables. Since the top and bottom are the same, you just list it once. Sorry, not the best explanation. Please let me know if I am wrong. It's been a while since I had to any type of algebra.
