Answer:
16x -12y = 4
15x +12y = 27
Step-by-step explanation:
4x-3y = 1
5x+4y=9
Multiply the first equation by 4
16x -12y = 4
Multiply the second equation by 3
15x +12y = 27
Answer: y = 10 + x / 5
Step-by-step explanation:
Answer:
Assuming that you're calculating surface area it would be:
16+10+10+10+10 or B
Step-by-step explanation:
Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
