Answer:
x=9
Step-by-step explanation:
step one pull out the factors
3x - 27 = 3 • (x - 9)
and step two: Equations which are never true
2.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
so x-9=0 and add both sides to 9 and to equal 9
Answer:
8/5 times 25/4 times 8/5
Step-by-step explanation:
Answer:
1. m=4
2. 6m-6
Step-by-step explanation:
well 3m=12 divide 3 on both sides m=4
so 6(m)=6m-6(1)= 6m-6
Answer: 10 because of Pythagorean theorem
