To get from 27 to 67.5 you multiply 27 by 2.5 so you need to do the same to the 5
5x2.5=12.5
=12.5in
I don’t understand your question can you go into more detail please
C) if you multiply it you get w^2 + 7w +11w+77, which is w^2+18w+77
Answer:
x+y = 112 ........ (1)
x-y = 62............ (2)
from (1) and (2)
2x = 174
x = 174/2
x = 87
sub x = 87 in (1)
x+y = 112
87+y = 112
y = 112 - 87
y = 25
so the numbers are 87 and 25

Hi!




Explanation: <u><em>This question is super easy. First you had to used 10^8 and it gave us 100,000,000. You can also multiply by 19.2*100,000,000 and it gave us the answer is 1,920,000,000 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
