There are 12 more of white and blue cars than silver and red cars
Step-by-step explanation:
Step 1 :
Number of black cars counted by Ed = 23
Number of red cars counted by Ed = 9
Number of blue cars counted by Ed = 17
Number of white cars counted by Ed = 25
Number of silver cars counted by Ed = 21
We need to determine how many more white and blue cars are there than silver and red cars
Step 2 :
Total of white and blue cars = 25 + 17 = 42 cars
Total of sliver and red cars = 21 + 9 = 30 cars
Difference = 42 - 30 = 12 cars
Hence there are 12 more of white and blue cars than silver and red cars
Step 3 :
Answer :
There are 12 more of blue and white cars than red and silver cars
The difference between two numbers is 19. Half the larger number plus twice the smaller number is 12. What are the numbers?
This is the equation I came up with but I can't make it work.
x-y=19
1/2x+2y=12
Answer:
tan

Answer:
Its D
Step-by-step explanation:
Find some graphing paper and graph away..
i.e. Sub in x = 0 and find what y = ?
y = 1/2(0) + 3
y = 3
So we know the coordinate (0,3)
When x = 4 , y = ?
y = 1/2(4) + 3
y = 4/2 + 3
y = 2 + 3
y = 5
So we know another coordinate (4, 5)
When x = -4, y = ?
y = 1/2(-4) + 3
y = -4/2 + 3
y = -2 + 3
y = 1
So we know another coordinate (-4, 1)
Putting it all together, the coordinates: (-4, 1) , (0, 3) and (4, 5) should be plenty sufficient to graph and then draw a line of best fit connecting them.
