A.
B.
Megan's solution isn't correct.
The first mistake: she subtracted 5x from the right-hand side of the equation, but added 5x to the left-hand side.
The second mistake: she divided the right-hand side of the equation by 11, but didn't divide the left-hand side.
The correct solution:
9514 1404 393
Answer:
B They are similar, but not congruent.
Step-by-step explanation:
Reflection, rotation, and translation are "rigid" transformations. They result in congruent figures.
Dilation is not a rigid transformation. For any dilation scale factor other than 1, the figures will be different sizes, so will not be congruent. They will be similar. (Angles will be congruent, and lines/sides will be parallel.)
The combination of dilation (by 0.5) and reflection results in similar, but not congruent, figures.
Answer:
7
Step-by-step explanation:
The LCM or least common muitiple is the least common number between the two numbers when you muitliply them.
3*7=21
Therefore, 7 is the answer.
Well, the way you wrote it ... 22/7 ... it's not a decimal at all.
It's an improper fraction. But I understand what you mean.
Remember ... a fraction is a short way to write a division problem.
Whenever you see a fraction, it means
(the top number) divided by (the bottom number) .
If you take your pencil and paper, or your calculator, and do
the division '22' divided by '7' ... very easy to do; you really
should have done it on your own ... you get
3.142857...
That group after the decimal point ... the " 142857 " ... does
repeat forever. So 22/7 does produce a repeating decimal.
