Answer:
57
Step-by-step explanation:
Answer:
2000J
Step-by-step explanation:
mg=500
h(height)=4
500 x 4 = 2000J
18x + 20 + x = 10x -3
Combine like terms
19x + 20 = 10x -3
Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:
19x = 10x -23
Subtract 10x
9x = -23
Divide 9 to isolate x:
x = -23/9
Simplify to get a mixed number:
x = -2 5/9
Samples versus population
a population is a composed of the entire group of people that could possibly be included in your study
population Generalization
the main purpose sampling quantitative research so that researchers so that generalize about the population and that means it is conducted
Switch sides of your problem so it would look like
r -5=-4
20
multiply both sides by twenty
after that it would look like r-100=-80
then add 100 to both of your sides
then after your answer would be r=20
