Solve for c by simplifying both sides of the equation, then isolating the variable.
C=36.5
Use Math..way. Put in equation, hit solve, will give u val. for N
The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
M(x, y) = ((x1 + x2)/2, (y1 + y2)/2) = ((-2 + 4)/2, (5 - 9)/2) = (2/2, -4/2) = (1, -2)
Answer:
1. 8/$12=21/$x then cross multiply.
2. 1/$1.5, we're looking for cost so $1 is more reasonable
3. $31.5
Step-by-step explanation:
12x 21/ 8 = 31.5
