Answer: the answer should be B
Answer:
6x = 48, 180/z = 90, and 10y + 8 + 138 = 180
Step-by-step explanation:
48 and six x are vertical angles they form a kind of x so they are complementary or equal
180/z and the 90 degree angle are supplementary meaning they add to 180 so 90 minus 180 = 90
the same thing is true for 10y + 8 its supplementay with 138 so 10y + 8 + 138 = 180
Equations and inequalities are figured the same way except for that one rule with inequalities...multiplying/dividing by a negative number changes the inequality sign.
Basically, u get the variable terms on one side and everything else on the other side...then solve for the variable. The only thing that would make it faster is if u had fractions...u would turn those fractions into whole numbers by multiplying by the lowest common denominator.
Other then that, I dont know how u could make it faster.
3 sides are equal
so
4x - 30 = 3x - 5
4x - 3x = -5 + 30
x = 25
Answer:
3
Step-by-step explanation:
f(x) =(1/9 )*(9x)
f(3)=(1/9 )*(9*3)
f(3)= 3
