If I have 16 card my brother as 3 times that amount and my sister has 16 more than him how many do we have all together

you have 64 cards in all

Step-by-step explanation:

16 x 3 = 48

48+ 16 = 64

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
