Find the answer to 2x and 5. Solve for X if possible.
Answer:
The original price of the phone is £388.
Step-by-step explanation:
Since 5% of the price of the phone is reduced, you can simply multiply the reduced number which is £19.4 by 20. Your final answer should be £388 when you put it on a calculator or do it on a piece of paper.
6x-8
There is 8 less (so -8) than the product of 6 and x (so 6x).
Plane's air speed is 437.5 mph
Wind velocity is 87.5 mph
An actual question hasn't been asked, but an educated guess would be to determine the plane's airspeed or the wind velocity. So I'll calculate those values for you.
When traveling with the wind, the combined speed is 2100/4 = 525 mph.
When traveling against the wind, the combined speed is 2100/6 = 350 mph.
So we can create 2 equations with 2 unknowns. They are:
a - b = 350
a + b = 525
Let's add the two equations together.
a - b = 350
a + b = 525
2a = 875
a = 437.5
So the plane's speed in still air is 437.5 mph.
Let's calculate the wind velocity.
a + b = 525
437.5 + b = 525
b = 87.5
And the wind velocity is 87.5 mph
If you would like to know how much money did they collect in total, you can calculate this using the following steps:<span>
Travis ... t = $43
Jessica ... j
Robin ... r
120% of j is t
120% * j = 43
120/100 * j = 43
j = 43 * 100 / 120
j = $35.83
r = 135% of t = 135% * 43 = 135/100 * 43
= $58.05
t + j + r = $43 + $35.83 + $58.05 = $136.88</span>
<span>The correct result would be C. $136.88.</span>
