Answer:
100.00
Step-by-step explanation:
x=number of months until the costs are the same
50 + 20x = 25 + 30x
25 = 10x
x = 2.5 months
50 + 2.5(20) =$100.00
Answer:
100
Step-by-step explanation:
because it is the nearist hundred and the closest hundred to 3 has to be 100
Answer: x ≥ 6
<u>Step-by-step explanation:</u>
12 less <u>than</u> 5 times a number ≥ 6 more <u>than</u> twice the number
5x - 12 ≥ 2x + 6
Note: the word "than" switches the order of the terms.
5x - 12 ≥ 2x + 6
<u>-2x +12</u> <u>-2x +12 </u>
3x ≥ 18
<u>÷3 </u> <u> ÷3 </u>
x ≥ 6

Answer:

Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of

inch thickness.
So when the two
inch thick book is being piled on the top of a
inch thick books.
Therefore, the total thickness of the pile of books is given by :



Therefore, the thickness of the pile is
.
Answer:
P(A) = 0.57 (to the nearest hundredth)
Step-by-step explanation:
There are 7 letters in total
4 of them are the letter A
⇒ P(A) = 4/7
= 0.5714285714...
= 0.57 (to the nearest hundredth)
