<span>x-axis: hours in increments of 1; y-axis: miles in increments of 5
You always want the constant numbers such as time on the x-axis
And since your y values are all large numbers and multiples of 5, it makes sense to use increments of 5</span>
Answer:
25*3*8=600
Step-by-step explanation:
25 students has 3 markrers for each then 25*3 is 75, after that marker come in packages of 8,so 75*8 is 600 packages.
The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8 (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.
