Answer:
![\frac{9}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B16%7D)
Step-by-step explanation:
Let total number of students![=x](https://tex.z-dn.net/?f=%3Dx)
Students went to the book fair:
Students went to book fair![=\frac{15}{20}\times total\ number\ of\ students=\frac{15}{20}x](https://tex.z-dn.net/?f=%3D%5Cfrac%7B15%7D%7B20%7D%5Ctimes%20total%5C%20number%5C%20of%5C%20students%3D%5Cfrac%7B15%7D%7B20%7Dx)
Students who bought book:
![Students\ who\ bought\ book=\frac{12}{16}\times Number\ of\ students\ went\ to\ book\ fair=\frac{12}{16}\times \frac{15}{20}x=\frac{9}{16}x](https://tex.z-dn.net/?f=Students%5C%20who%5C%20bought%5C%20book%3D%5Cfrac%7B12%7D%7B16%7D%5Ctimes%20Number%5C%20of%5C%20students%5C%20went%5C%20to%5C%20book%5C%20fair%3D%5Cfrac%7B12%7D%7B16%7D%5Ctimes%20%5Cfrac%7B15%7D%7B20%7Dx%3D%5Cfrac%7B9%7D%7B16%7Dx)
Hence
of total students bought at least one book.
Answer:
60
Step-by-step explanation:
1/6(x+6)=11
1/6x+1=11
1/6x=11-1
1/6x=10
1/6/1/6=10/1/6
10x6=60
pls brainliest
K + a + h = 50
a = 2h
k = h - 10
(h - 10) + 2h + h = 50
4h - 10 = 50
4h = 50 + 10
4h = 60
h = 60/4
h = 15 <=== Henry sent 15
a = 2h
a = 2(15)
a = 30 <=== Aldo sent 30
k = h - 10
k = 15 - 10
k = 5 <=== Keiko sent 5
Answer:
Step-by-step explanation:
4x + 4 - 3
= 4x + 1
Yes they both are equivalent because the algebraic expression is same
