Step-by-step explanation:
Only D, y = 3x + 12 is in slope-intercept form.
10 x 40 = 400 so the answer is 400 pieces of chalk.
Since 3 divides 42, 3xy itself is the greatest common factor of 3xy and 42xy.
Answer: 3xy
Answer:
x=1
Step-by-step explanation:
5x-(x+1)=5-2x
distribute
5x-x-1 = 5-2x
4x-1 = 5-2x
add 2x on each side
4x-1+2x = 5-2x+2x
6x -1 = 5
add 1 on each side
6x-1+2 = 5+1
6x = 6
divide by 6
6x/6 = 6/6
x = 1
