Answer:
B
Step-by-step explanation:
Answer:
These are some examples of recurring decimals.
Definiton:
A repeating decimal or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero.
Step-by-step explanation:
the first one if you are solving for x it will be x=21-8y
if you are solving for y it will be y =21/8 - x/8
the second one will be if you are solving for x x = 2 -5y/3
solving for y is y=6/5-3x/5
Answer:
x = (cy+b)/a
Step-by-step explanation:
ax-b=cy
Add b to each side
ax-b+b=cy+b
ax = cy +b
Divide each side by a
ax/a = (cy+b)/a
x = (cy+b)/a
Answer:
2 times
Step-by-step explanation:
the length and breadth of the parallelogram will be l and b, respectively.
Then, perimeter = 2(1 + b) [∵ perimeter of parallelogram = 2 x (length + breadth)]
If both sides are increased twice, then new length and breadth will be 21 and 2b, respectively.
Now, new perimeter = 2(21 + 2b) = 2 x 2(l + b) = 2 times of original perimeter.
the perimeter of parallelogram will be increased 2 times.
