Answer: Note that

1 ream of paper = 500 sheets (or pages printed)

Each book has

1/2 page for each letter of the alphabet = (1/2)*26 = 13 pages

A title page = (1/2)*1 = 1/2 page

An end page = (1/2)*1 = 1/2 page

Total pages per book = 13 + 1/2 + 1/2 = 14 pages.

There are 70 students, therefore the number of pages needed is

14*70 = 980 pages

The number of reams of paper required is

980/500 = 1.96 ≈ 2 reams

Answer: 2 reams

MIDDLE SCHOOL

Write an expression for 8 times x

8x

8(x)

Either one works ^^

an expression would be 8x because 8 times x equals 8x

MIDDLE SCHOOL

What's bigger 9/10 or 4/5

To be able to compare 2 fraciton we have to make common denominator and then we can just compare numerators.

Now we can compare numerator from the first (9) and from the second fraction (8)

9>8, so the bigger is 9/10

Now we can compare numerator from the first (9) and from the second fraction (8)

9>8, so the bigger is 9/10

9/10 because smaller pieces and has more of them

Find the second of 3 consecutive integers if the sum of the first and the third is 26

X= 1st integer

x+1= 2nd integer

x+2= 3rd integer

Add the 1st and 3rd set equal to 26.

x + (x+2)= 26

combine like terms

2x + 2= 26

subtract 2 from both sides

2x= 26

divide both sides by 2

x= 13

Substitute x=13 to find 2nd integer.

= x+1

= 13 + 1

= 14 second integer

ANSWER: The second integer is 14.

Hope this helps! :)

x+1= 2nd integer

x+2= 3rd integer

Add the 1st and 3rd set equal to 26.

x + (x+2)= 26

combine like terms

2x + 2= 26

subtract 2 from both sides

2x= 26

divide both sides by 2

x= 13

Substitute x=13 to find 2nd integer.

= x+1

= 13 + 1

= 14 second integer

ANSWER: The second integer is 14.

Hope this helps! :)

Find the value of the expression below. log4 3 + log4 8 - log4 6

The question can be solved as:

log4^3 + log4^8 - log4^6

= 3log4 + 8log 4 - 6 log4

(Because log n ^ m = m log n)

= 5 log 4

= 5log (2^2)

(Because 4 can be written as 2^2)

= 5*2 log 2

= 10 log 2

= 10*0.3010

(Because log 2 = 0.3010)

= 3.010

log4^3 + log4^8 - log4^6

= 3log4 + 8log 4 - 6 log4

(Because log n ^ m = m log n)

= 5 log 4

= 5log (2^2)

(Because 4 can be written as 2^2)

= 5*2 log 2

= 10 log 2

= 10*0.3010

(Because log 2 = 0.3010)

= 3.010
