Answer: x = 40
Step-by-step explanation:
these two angles are vertical angles, they will equal each other
therefore, move numbers and variables to the opposite sides of the = sign to isolate the X
3x-10 = 2x + 30
+10 +10 move the -10 by doing opposite
_____________
3x = 2x + 40
-2x -2x move -2x by doing opposite
____________
x = 40
you can check your work by substituting 40 in place of x
3(40) - 10 = 2(40) +30
120-10 = 80 + 30
110 = 110
answer is correct
The formula is
A=p (1+r/k)^kn
A future value?
P present value 500
R interest rate 0.05
N time 4 years
K compounded monthly 12
A=500×(1+0.05÷12)^(12×4)
A=610.45
27km* 10^6= 2,700,000cm
Or
1km is 1,000,000 cm, so that means 27 km is 2,700,000 cm
Hope this helps :)
