Answer:
x = 6
Step-by-step explanation:
20 = 7x + 2 - 4x
7x + 2 - 4x = 20 (switch the sides)
7x - 4x + 2 = 20 (group the like terms together)
3x + 2 = 20 (add similar numbers, in this case it's the both x's)
-2 -2 (subtract 2 on both sides)
------------------
3x = 18
/3 /3 (divide both sides by 3)
-------------------
x = 6
Answer: 103 mm
Step-by-step explanation: The conversion factor from centimeters to millimeters is 10, which means that 1 centimeter is equal to 10 millimeters: 1 cm = 10 mm. To convert 103 centimeters into millimeters we have to multiply 103 by the conversion factor in order to get the length amount from centimeters to millimeters.
Answer:
100
Step-by-step explanation:
because -100 0 then positive 100
Answer:
111.58 feet
Step-by-step explanation:
Given that the length of the string (AB in the attached diagram) is 120 feet.
Selena (at point D) is standing 24 feet from point A, where the kite is attached to the ground.
Since the kite is directly above Selena's head, the problem forms a right triangle.
Using Pythagoras theorem
Serena's height (CD=6 feet)
The distance of the kite above her head is BC in the drawn diagram.
Therefore:
|BD|=|BC|+|CD|
117.58=|BC|+6
|BC|=117.58-6
|BC|=111.58 feet
The kite is approximately 111.58 feet above Selena's head/
About $43,000 because if you look on the graph, look for 2018 and go up until you meet the line. Then, using that, you can move left to the sales indication. The line hits 2018 between 40,000 and 45,000, so it is $43,000.
