- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em />
<em>60% .......... $66</em>
<em>100% ..........$ x</em>
<em>x = 100×66/60</em>
<em>= 6600/60</em>
<em>= $ 110</em>

<em>Good luck !</em>
R is between S and T, so this implies that R is on line ST and we can say
SR+RT = ST
plug in the given expressions to get
(-2x+24)+(4x+10) = 4x+12
Now solve for x
(-2x+24)+(4x+10) = 4x+12
-2x+24+4x+10 = 4x+12
2x+34 = 4x+12
2x+34-2x = 4x+12-2x
34 = 2x+12
34-12 = 2x+12-12
22 = 2x
2x = 22
2x/2 = 22/2
x = 11
If x = 11, then RS is,
RS = -2*x+24
RS = -2*11+24
RS = -22+24
RS = 2

Answers:
x = 11 and RS = 2
The amount in dollars that is in the account after 50 years expressed in power is; 2⁹
<h3>How to apply the rule of exponents?</h3>
We are told that the money doubles in value after every 10 years.
When the account was opened it had 2⁴ dollars in it and after 50 years it has doubled 5 times. The doubling increased by a factor of 2⁵ and is now has a balance of 2⁴ × 2⁵.
Using the rule of exponents, we have;
2⁴ × 2⁵ = 2⁹

3f-2-f would probaly be your answer
Answer:
We let x be the number of hours both could the job together.
The fraction of the job done by Elias is
x/40
The fraction of the job done by Niko is
x/50
Together they would be able to finish the job
x/40 + x50 = 1
x = 1 / (1/40 + 1/50)
x = 22.22 min
