7) let a = ℤ and r be the relation on a where a r b if and only if a + b is a multiple of 4. determine whether r is reflexive, irreflexive, symmetric, asymmetric, antisymmetric, or transitive. for each property, either explain why r has that property or give an example showing why it does not.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
