Answer:
x = 4
Step-by-step explanation:
4(x-9)=3x-8x
Follow distributive property
4x - 36 = 3x - 8x
Combine like terms
4x - 36 = -5x
Subtract 4 from both sides
-36 = -9x
Divide both sides by -9
x = 4
Answer:
C $320
Step-by-step explanation:
write equations for the two possible choices
situation 1:
y₁ = 20 + 0.5x, where y is the total price the club pays and x is the sales
** note i use 0.5 instead of 50, since 50 would represent 5000%
y₂ = 100 + 0.25x, where y is the total price the club pays and x is the sales
now set the two equations equal to each other
20 + 0.5x = 100 + 0.25x
isolate x by subtracting 0.25x and 20 from each side
20 + 0.5x - 0.25x - 20 = 100 + 0.25x -0.25x -20
0.25x = 80
divide both sides by 0.25
=
x = 320

Volume of the object =
Answer:
x = 14
Step-by-step explanation:
let the number be x.
- 4 times the number = 4x
- 10 added to 4 times the number = 4x + 10
now,
- 5 times the number = 5x
- 4 less than 5 times the number = 5x - 4
Given that,
4x + 10 = 5x - 4
moving all x terms to the LHS and the constants to the RHS
4x - 5x = -4 - 10
-x = -14
dividing both sides by -1
<u>x = 14</u>
A) An inequality to represent the temperatures the pilot can take off and land in is .
B) The graph is shown below, it shows the temperature range in which the aircraft can takeoff or land.
C) The pilot could not have taken off on June 1990, the temperature in Phoenix, Arizona as the temperature is above the operating limitations.
Let the operating temperature be .
The aircraft cannot operate if the temperature is at or below ° F, or at or above ° F.
So, the inequality will be .
In the graph, the shaded region represents the temperature in which the temperatures the pilot can take off and land in. Here, we can see open circles at the end points as they are not included in the interval.
The temperature cannot be at or above 118° F. So, the pilot could not have taken off on June 1990, the temperature in Phoenix, Arizona as the temperature is above the operating limitations.
