Answer:
x ≥ 15
Step-by-step explanation:
200 + 20x ≥ 500
To solve this inequality, you must first subtract 200 from 500.
500 - 200 = 300.
Lastly, divide 300 by 20.
20x = 300
300 ÷ 20 = 15
Therefore, the value of x is 15.

Answer:
Step-by-step explanation:
By similar triangles, you get
3/BD = BD/7
BD^2 = 21
BD = √21
Now you use Pythagoras to get x
7^2 + BD^2 = x^2
49 + 21 = x^2
60 = x^2
x = √60
7.746
Answer:
40 sq cm
Step-by-step explanation:
This
area = length times width so 5 times 8 is 40
Answer:
x = 76°
Step-by-step explanation:
At point I
to get angle JID
angle JID + 107° = 180°. (angle on a straight line)
angle JID = 180° - 107°
angle JID = 73°
for Triangle JiD
angle DJI + 31° + 73° = 180° (Sum of angles in a triangle)
angle DJI = 180 - 104 = 76°
angle FJI = 31 + 73 =104°. ( Sum of two interior angles in a triangle is equal to one exterior angle)
Hence,
x° + 104° = 180° (angle on a straight line)
x = 76°
