Lisa took a trip to Kuwait upon leaving she decided to convert all of her dinars back into dollars how many
Answer:you would have saved $31 after 5 days
Step-by-step explanation:
You double the number of dollars in the envelopes from the day before. This means the amount in a day is double the amount in the previous day. Therefore, amount of money in the envelope is increasing in geometric progression. The formula for determining the sum of n terms of a geometric sequence is expressed as
Sn = a(r^n - 1)/r - 1
Where
a represents the first term.
r represents the common ratio.
From the information given,
a = 1
r = 2
n = 5 days
S5 = 1(2^5 - 1)/2 - 1
S5 = 32 - 1 = 31
Answer: k=54/79
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 16/3k from both sides.
Step 3: Subtract 5/2 from both sides.
Step 4: Multiply both sides by 12/(-79).

116+y=180(sum of angles in a straight line)
y=180-116
y=64
x+y+125+72=540(sum of angles in a quadrant)
x+64+125+72=540
x+125+136=540
x+261=540
x=540-261
x=79
