Area parlalelogram=base times height
areatrapizod=(1/2)(base1+base2) times height
areatriangle=1/2 times base times height
1. area=(1/2)(5.9+16.3) times 4.6=51.06
first option
2. area=1/2 times 20.3 times 6.2=62.93
2nd option
3. area=5 and 1/4 times 3=15.75 or 15 and 3/4 or
4th option
4., area=1/2 times 14 times 5.5=38.5
3rd option
5. area= 5.2 times 2.3=11.96
4th option
Answer:
Betsy will save $121 in 5 weeks.
Step-by-step explanation:
We can see that Betsy's savings are 3 times the saving of her last week. We can see that this is an geometric sequence as 1,3,9,..
To find the sum of our geometric sequence we will use
, where n is number of terms we are taking sum of, a is first term of sequence and r is common ratio of the sequence.



Therefore, Betsy will save $121 in 5 weeks.
Answer: 22 /5
-3+7y=5x+2y
Step-by-step explanation:
Subtract 2y from each side
-3+7y-2y=5x+2y-2y
-3 +5y = 5x
Add 5 to each side
5y = 5x+3
Divide each side by 5
y = 5x/5 +3/5
y = x +3/5
Let x = -5
y = -5 + 3/5
y = -25/5 +3/5
y = -22/5
