Answer:
<em>q</em> = 12<em>x</em>
Step-by-step explanation:
<em>q</em> = 3<em>x</em> + 9<em>x</em>
Combine like terms
<em>q</em> = 12<em>x</em>
This question is an example of d = r * t
r = rate
r = 3*10^8 m/s
t = ??
d = 7.5 * 10^6 meters.
Sub and solve
d = r * t
7.5 * 10^6 = 3 * 10^8 * t Divide both sides by 3 * 10^8
7.5 * 10^6 / (3 * 10^8) = t
2.5 * 10^(6 - 8) = t
2.5 * 10^-2 seconds = t or
0.025 seconds = t
Answer:
7542.99
Step-by-step explanation:
20,000(0.85)6
7.
Discounted price X
————————— = ———
Original Price 100
45 x
—- = —-
72 100
Cross multiply
45 times 100= 4500
72 times x= 72x
72x=4500
Divide
4500/72= 62.5%
