He is only 0.6 seconds behind so it is a fair race
They are both correct! Michael's equation is just a distributed version of Laurie's equation. Laurie's equation is solved like this: First distribute to get
2x + 1.2 + 0.8 + 0.7, then add the numbers together to get 2x + 2.7.
Michael's equation also starts with distributing to get 2x + 1.2 + 0.8 + 0.7 and adding the numbers together to get the same answer: 2x + 2.7. Hope this helps!
Answer:
see below
Step-by-step explanation:
10 markers =7 dollars
Divide each side by 10
10/10 = 7 /10
1 marker = 7/10
y =7/10 x where y is the cost and x is the number of markers
24 markers =14 dollars
Divide each side by 24
24/24 = 14 /24
1 marker = 7/12
y = 7/12 x where y is the cost and x is the number of markers
Answer:
x = -24/5
Step-by-step explanation:
2x – 3 + 3x = – 27
Combine like terms
5x -3 = -27
Add 3 to each side
5x-3+3 = -27+3
5x = -24
Divide each side by 5
5x/5 = -24/5
x = -24/5
