Answer:
22°
Step-by-step explanation:
Vertically opposite angles are equal
5x+18=118
Grouping like terms
5x=118-18
5x=110
x=22

Answer:
Amount of money Elsa spent= amount of money given by grandmother,x - amount of money saved.
Hence for the first four weeks, amount spent= 4(x-10) as she saved 10 per week for 4 weeks.
For the next eight weeks, amount spent= 8(x-15) as she saved 15 per week for 8 weeks.
Thus the answer would be the first option.
2x-y=4
Therefore: y=2x-4
---------------------------------
5x-10/4(2x-4)=10
5x-5/2(2x-4)=10
5x-5x+10=10
10=10
------------------------
*Problem can't be solved.
Exponential growth function is given by f(t) = A(1 + k%)^t; where A is the initial value, k is the growth rate and t is the time period.
Therefore, the required function is
f(t) = 120,000(1 + 0.012)^t = 120,000(1.012)^t
After 15 years, the new population is 120,000(1.012)^15 = 120,000 x 1.1959 = 143,512
