Whenever you work any "solve for" problem, you start by looking at what is done to the variable of interest. Here, a is multiplied by 2s and added to v². You must reverse these operations, generally in reverse order.
V² -v² = 2as . . . . . . . . subtract v²
(V² -v²)/(2s) = a . . . . . divide by the coefficient of a
Solved for a, the formula is ...
... a = (V² -v²)/(2s)
Answer: A: 180= 90+4x+x
B: x=18
Step-by-step explanation:
1. Every triangle has a length of 180
2. So all the measurements combined would equal 180
3. So write the equation 180=90+4x+x
4. Let‘s simplfy, 180=90+5x
5. Subtract 90 from each side, 90=5x
6. Divide each side by 5, 18=x.
7. Double check our work! 90+(4*15)+18=180
Answer:
Step-by-step explanation:
We can divide 3 out of all three given terms:
3(16x - 2 + y/3)
is one possibility. Where are the answer choices that you were given?
Note: 48x-6+3y/3 is an expression in x and y, but is not an equation. Is that what you intended?
Answer:
y=5
Step-by-step explanation:
y= 5 is always parallel to x axis
