Answer:
After the sale there were 15 cars and 5 motorcycles
Step-by-step explanation:
c=cars originally
m=motorcycles originally
c=2m (2 times the cars than motorcycles)
(c+1) bought 1 car after sale
sold 1 motor cycle (m-2) after sale
(c+1) = 3(m-2) (3 times more cars than motorcycles)
(c+1) = 3(m-2)
distribute
c+1 = 3m-6
substitute c =2m
2m +1 = 3m-6
subtract 2m from each side
2m+1-2m = 3m-6-2m
1 = m-6
add 6 to each side
1+6 = m-6+6
m=7
c = 2m
c = 2(7) =14
c=14
Originally there were 7 motorcycles and 14 cars
After the sale c+1 = 15, m-2 = 5
there were 15 cars and 5 motorcycles
Answer:
Step-by-step explanation:
There are 2 rays GF and GA
The line is AC
The Segment is CE. You could argue that GC is also a segment. I don't think it is the intended answer. As an answer, CE is much safer.
Answer:
a.) 10% is correct. If you add them all together it's 50 pennies. Lincoln and steel pennies equal 10 and 10 of 50 is 10%
Answer:
The coefficient of squared term is 1/9
Step-by-step explanation:
The vertex of parabola is (2.-3)
We know the vertex form of a standard parabola
Plugging values of h and k, h= 2, k = -3
Now, x=5, y=-2
Thus, the coefficient of squared term is 1/9
Answer:
It is B, D and F
Step-by-step explanation:
because red 2 is very specific and not putting it back in the deck makes it independent
