Answer:
40
Step-by-step explanation:
to make 17 a fourth multiply it by 4, = 68
the original number of books in the library was 28
68-28 = 40
40 = number of books added to make 17 a fourth
Replace y with 15
The equation is now:
1x - 15 = 30
Add 15 to both sides:
1x = 45
Divide both sides by 1
X = 45
The whole rectangle is in the 1st dimensions.
For how to do this, you need draw it in a grid chart.
Answer: 31 and 1/9
d =29, for g=16,h=9
replace values of each number in equati/on:
d+g/h=29+19/9=(9*29+19)/9=( 261+19)/9=280/9= 31 and 1/9
