Answer:
Step-by-step explanation:
so what you need to do is 112=16m+12b
m=magazines
b=books
Answer:
1a) Length = 7x + 3 & Width = 4x - 2
1b) Area = 
1c) Area = 2774 sq. m
2. 
Step-by-step explanation:
1a)
The length given as words is "3 more than 7 times x"
The width given as words is "4 times x minus 2"
The expression for length would be 7x + 3
The expression for width would be 4x - 2
1b)
The area is length * width
Since we already know the algebraic expressions for length and width from part (a) above, we use the formula:
Area = (7x+3)(4x-2) = 28x^2 -14x + 12x - 6 = 28x^2 -2x -6
Area = 
1c)
Given x = 10, we put this into the area expression we found in (b) above.Let's see:

Area = 2774 sq. m
2.
We can group the first two terms and next two terms and write up:

That's the factored form.
Answer:
BC= 29
Step-by-step explanation:
If the total, AC, is 54 and AB is 25 subtract those two to find the last part, BC.
50% can also be written as (1/2)
Multiply the two known values:
24 x (1/2)
This is equal to (24/2). Simplify the fraction by dividing:
(24/2) = 12

I hope this helps!
250.6 is your number
The "6" in .6 right after the decimal is the tenths place
So right after the tenths place is the hundredths place
But as you can see in 250.6, there is no hundredths place you can see so it is 0
250.60 is the same as 250.6
So 250.6 is already rounded to the nearest hundredths
