Answer:
The equation needed is 
The cost per ream of paper = $4
Step-by-step explanation:
Here, the cost of 5 reams of paper = $ 21
The tax on her purchase = $1
So, the actual cost of 5 reams of paper = Total Cost paid - Tax amount
= $ 21 - $ 1 = $20
So, the actual cost of 5 reams of the paper is $20.
Now, to find out the cost of 1 ream of paper:
= $4
Hence, the cost of each ream of paper = $ 4.
<h3>Solution:</h3>
-38d - 57 = -19d + 76
or, -38d + 19d = 76 + 57
or, -19d = 133
or, d = 133/-19 = -7
<h2>Answer: d = -7</h2>
<h3>To Check:</h3>
By putting the value of d, we get
-38(-7) - 57 ≥ -19(-7) + 76
or, 266 - 57 ≥ 133 + 76
or, 209 ≥ 209
Hence, Verified.
Answer:
The correct answer is:
x ≤ 14 (b)
Step-by-step explanation:
first of all, let us find the other side of the rectangle using the limit of 46 as the highest perimeter:
Perimeter of a rectangle = 2(Length) + 2(width)
Let the length = x inches
let the width = 9 inches
Perimeter = 2x + 2(9)
46 = 2x + 18
2x = 46 - 18
2x = 28
x = 28 ÷ 2
x = 14
Therefore, for the perimeter to be equal to 46 inches, the other side of the rectangle must be equal to 14 inches. Hence, for the perimeter to be at most 46 inches ( 46 inches or less):
x is less than or equal to 14 (x ≤ 14)
3x+7+5x-4=67
8x+3=67
8x=64
x=8, now sub 8 for x
3(8)+7
24+7=31
Answer:EF=31
Square root of 6 times 16 will give us 39.19
The square root of 48 times 32 [which gives us 1536] is also equal to 39.19
The square root of 1536 is equal to 39.19
Hence, x is equal to 32
Hope this helped! :D
