Answer:
d = 3 c= 1/4
Step-by-step explanation:
Eq. 1) -4c + 5d = 14
Eq. 2) -4c + 3d = 8 ( the written Eq. says 40 but I am guessing it's 4c )
subtract Eq. 1 and Eq. 2
2d=6
d=3
plug 3 in for d in Eq. 1
-4c + 5(3) = 14
-4c + 15 = 14
-4c = -1
c = 1/4
Answer:
B. 55.10
Step-by-step explanation:
Given:
1 pair of Shoes for 1st year = $50
2 pair of Sock for 1st year = $2 each = 2
2= $4
CPI for year 1 = Price of shoes for 1st year + Price of Sock for 1st year= $50 + $4 = $54
Now
1 pair of Shoes for 2nd year = $51
2 pair of Sock for 2nd year = $2.05 each = 2 2.05 =$4.10
CPI for Year 2 = Price of shoes for 2nd year + Price of Sock for 2nd year= $51 + $4.1 = $55.10
Hence CPI for Year 2 is $55.10
Answer:
2/15
Step-by-step explanation:
Given that she have already read one-third of the book.
The fraction f of the book that will remain is;
f = 1 - 1/3 = 2/3
Then she finishes the book by reading the same amount each night for 5 nights
That implies she reads the remaining 2/3 of the book at equal rates for 5 nights.
Let x represent the fraction rate read per night;
5x = 2/3
Divide both sides by 5
x = 2/3 × 1/5
x = 2/15
Therefore, she reads 2/15 of the book every night for 5 nights.
