Is this simultaneous equations?
if yes then the first step is
make one of the unknown as the subject
1 sunflower costs $2.25
you divide 18 by 8
(the total costs by the number of flowers)
Answer:
Step-by-step explanation:
Given
Required
Determine an equivalent expression
Express 81 as
Apply law of indices
Hence:
Plug in 3 for f(x)
f(3)=(3)²+7
f(3)=9+7
f(3)=16
Hoped this helped!
Since we know that LCM of both 625&575 is 14375, we must find the hours it took for both planes to arrive at this same destination.
Plane 1(625): Took 23 hours to arrive.
Plane 2(575): Took 25 hours to arrive.
Therefore, the answer should be from 23-25 hours to arrive or if looking for middle number, 24 hours exactly.
Hope this helps.
