katrin [286]

Answer:

  • 64 = p - 9.75
  • p = 73.75

Step-by-step explanation:

A value that is 9.75 less than p can be represented by the expression ...

  p - 9.75

We are told that value is equal to 64, so the equation is ...

  64 = p - 9.75

__

This equation is solved by adding 9.75 to both sides.

  64 +9.75 = p -9.75 +9.75

  73.75 = p

The store price is $73.75.

The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more t
valentina_108 [34]
The answer is  0 < x <span>≤ 7 
</span>
First, we know that width =  x
Which means that length = x +18

So, the possible equation for the Table's area is

X (X + 18)  ≤ 175

X^2 + 18x - 175  <span>≤ </span>0

Next, we need to calculate is by using complete square method
x^2 + 18x + 81 <span>≤ 175 + 81

(x + 9)^2 </span><span>≤ 256

|x + 9| </span><span>≤ sqrt(256)

|x + 9| </span><span>≤ +-16

-16 </span>≤ x + 9 <span>≤ 16

</span>-16 - 9 ≤ x <span>≤ 16 - 9

</span>-25 ≤ x <span>≤ 7

Since the width couldn't be negative, we can change -25 with 0,

so it become
</span> 0 < x ≤ 7
