Answer:
its 45
reason is 216-81 = 135 divide by 135/3=45
Remember, you can do anything to an equation as long as you do it to both sides
and when multiply or divide by a negative in inequalities, flip the direction of the sign
12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4
-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4
It leaves a remainder of 3
that means is it NOT a multipule of 6 or 8 or 10
it has to be more than 10 though
6x+1=8y+1=10z+1
subtract 1 from everybody
6x=8y=10z
so basically what is the least common multplule and then add 1
LCM
factor
6=2*3
8=2*2*2
10=2*5
therefor the LCM=2*2*2*3*5=120
then add 1
120+1=121
the smallest intege is 121
Use the formula y=kx for this equation.
so considering that Y equals -24 then X and K must also equal that number
we already know that X is -4 but we dont know what K is.
so we divide -24 by -4 and get an answer of a positive 6 but the answer is not proven yet.
-4 times 6 is -24 meaning that the answer is 6
