Answer:
Step-by-step explanation:
<u>Set a ratio:</u>
- 7/8 hours ⇒ 2/5 chapters
- 1 hour ⇒ x chapters
<u>Find the value of x by cross-multiplication:</u>
- x = 1 × 2/5 ÷ 7/8
- x = 2/5 × 8/7
- x = 16/35

Answer:
G(x+2) = 7x^2 + 33x + 30
Step-by-step explanation:
So in the G(x) function, to find G(x+2), we just simply plug in the value of x+2 into the function and the result is what is wanted. SO:
G(x+2) = 7(x+2)^2 + 5(x+2) -8 , which is 7x^2 +33x +30 after SIMP - lifying (see what I did there ;)
Hope i helped, please make this brainly. :)
Answer:
$99
Step-by-step explanation:
MP3 Player: $100
10% Mark up: $100/10= 10
Therefore, Mark-Up Price: $100+$10= $110
This was then Marked down by 10%.
Therefore,
10% Marked down: $110/10= $11
(We then take this away from the marked up price)
Hence, Final Price : $110-$11= $99
