Answer:
x ≤ 7
Step-by-step explanation:
Let the cost of each book be $2
Let the amount of book she can buy be x
If she can spend no more than $15
Amount of book she can buy≤ Total amount/cost of each book
Amount of book she can buy ≤ $15/$2
Amount of book she can buy ≤ 7.5
x ≤ 7.5 OR x ≤ 7
Hence the required inequality is x ≤ 7. Less than or equal to was used since she can't spend more than $15
A is an absolute value if it is greater than zero. This simply means that an absolute value number will always be greater than zero. This is because absolute value is the distance from 0 on a number line. Keep in mind that distance cannot be negative. For example, look at the numbers 5 and -5. 5 is 5 spaces from 0, and -5 is also 5 spaces from 0, not -5 spaces from 0. Put simply, an absolute value number that is greater than 0, will always be positive.

Answer:
144 cm
Step-by-step explanation:
Bottom: 4x11 = 44
Side 3x4x1/2 = 6
Other side = 6 (same)
Slant = 3, 4 and the hypotenuse is 5 (pythagroem triple )
5x11 = 55
Back: 3x11= 33
44+6+6+55+33= 144
