x+50=60
Subtract 50 from both sides
x+50-50=60-50
x=10
The number is 10
Check your answer
Replace x by its number
x+50=60
10+50=60
60=60

Hey there!!
Original value - 114.6 million tons in 1950
Decrease by 6.6% every year.
6.6% = 0.066
1951 : 114.6 - ( 0.066 × 114.6 )
... 107.03 million tons
1952 : 107.03 - ( 0.066 × 107.03 )
... 99.9 million tons
1953 : 99.9 - ( 0.066 × 99.9 )
... 93.3 million tons
1954 : 93.3 - ( 0.066 × 93.3 )
... 87.1 million tons
1955 : 87.1 - ( 0.066 × 87.1 )
... 81.3 million tons
Doing this is going to take time.
Let me given an alternate method :
Let :
x = 0
a = 114.6
Be 1950
b = 1 - ( 6.6 / 100 ) = 0.934
x = 2010 - 1950 = 60
y = the million tons remaining :
y = 114.6 ( 0.934 ˣ )
y = 114.6 ( 0.934 ⁶⁰ )
y = 1.9 million tons.
Hence, the required answer is 1.9 million tons.
Hope my answer helps!
Answer:
37°
Step-by-step explanation:
As we know the sum of angles of a triangle is 180 degrees.
Therefore,
angle A + angle B + angle C = 180°
In the given picture two angles are given and we have to find out the third angle.
x° + 45° + 98° = 180°
x° + 143° = 180°
x° = 180° - 143°
x° = 37°
The value of x in the triangle shown is 37°.

To multiply complex numbers in trigonometric form, you simply multiply the radii and add the thetas. We have:
z1=5(cos(pi/2)+i sin(pi/2))
z2=2(cos(5pi/6)+i sin(5pi/6))
The radii for the above 2 numbers are 5 and 2. So the result will have a radius of 5*2 = 10. The thetas are pi/2 and 5pi/6, so the new theta will be pi/2 + 5pi/6 = 3pi/6 + 5pi/6 = 8pi/6 = 4pi/3. So the answer is:
10(cos(4pi/3) + i sin(4pi/3))</span>
