Answer:
the 3rd one matches the number line
Step-by-step explanation:
the pointy part of the sign shows which way the line will go. if it has the line under the sign the dot on the number line is solid if not solid then it won't have a line
We can divide the 300 by 900 to get the decimal equivalent of the percentage 300/900 = 1/3 = .33333
multiply that by 100 gives you a percentage of 33.33% increase in mark-up
hope this help
The easiest way is to just solve the equation.
4x - 4 = -4x + 60
4x + 4x = 4 + 60
8x = 64
x = 8
A slower way to do this is to plug each of the numbers into the equation to see which makes the equation is true.
So for A.
4(8 - 1) = -4(8) + 60
4(7) = -32 + 60
28 = 28
Fortunately, this is true, so A is the answer and you don't have to try the other options.
