Answer:
(f-g)(x)= f (x)- g (x) =4^x -1 +6 -(2x-5)
=4^x +5 -2x +5
=4^x -2x +10

"?" = 3
Step-by-step explanation:
The answer can be gotten by subtracting 4 from 7. The 4 is the exponent in (4a^4b), and the 7 is the exponent in 16a^7b. So:

1/3 of 45 is 15, meaning 15 students gave their speech on day 1
Today 2/5 of the remaining students gave their speech. That’s 12 more

Answer: 0.6kg of flour will be in each batch of scones.
Step-by-step explanation:
Adam has 16.45 kg of flour, and he used 6.4kg to make hot cross buns. This means that the remaining flour would be the total amount of flour that he had initially minus the the amount that he used to make hot cross buns. This is expressed as
16.5 - 6.4 = 10.05 kg
The remaining flour is exactly enough to make 15 batches of scones. This means that 10.05 kg of flour will be enough to make 15 batches of scones.
We want to determine how much flour, in kg, will be in each batch of scones. Let this amount of flour be xkg
If 10.05 kg of flour will be used to make 15 batches of scones. Then,
xkg of flour will be used to make 1 batch if stones
x = 10.05/15
x = 0.67
