Step-by-step explanation:
Solve for a
k + a = v + w
a = v + w - k
Solution → { a = v + w - k }
EXPLANATION
Given the equation:
1/5m = 4-3/10m (Adding +3/10 to both sides)
1/5m +3/10m = 4 (Adding 1/5 + 3/10)
1/2m = 4 (Isolating m)
m = 2*4 (Multiplying)
m=8
ANSWER: m=8
Well do u know how many there are?
Answer:
13) x=n-11
15) x=3*10
Step-by-step explanation:
I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
Answer:
Upwards
Step-by-step explanation:
The general form of a quadratic is 
We can tell whether the curve opens upward or downward by the sign of "a"
If
- a is positive, the curve opens upward
- a is negative, the curve opens downward
Reaaranging the given equation:

Here, we see that a is positive, so the curve opens Upward
