Step-by-step explanation:
1. divide 78% by 100 = 0.78
2. multiply 0.78 and 3.822
3. solve and get 2.98116
4. if you want you could round
5. x = 2.98166 or 3
Answer:
4.7 inches
Step-by-step explanation:
The original is 12.5, and it was shortened to 7.8. So take the original, subtract the result, and you will get the answer.
12.5-7.8=4.7
(2x - y)(x - 8y + 7) =
2x(x - 8y + 7) - y(x - 8y + 7) =
2x^2 - 16xy + 14x - xy + 8y^2 - 7y =
2x^2 - 17xy + 8y^2 + 14x - 7y <===
the change in x is 1 and 2 in y respectively
the points are in order from r (x,y) to m (9,8) to s (10,10
if we take - 1 from x and 2 from y we will get r, or (8,6)
