Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable solution if x represents the number of days that a library book is late and y represents the total fee?Answers:
(–3, –0.90)
(–2.5, –0.75)
(4.5, 1.35)
(8, 2.40)

Answers

The answer is (8, 2.40).

We can deduce this because if x is negative, it means the book is not late; it's early! We can cross out the first two answers. We know the third one is wrong because the fee is charged on midnight, so the fee for 4.5 days late would be the fee for 4 days late, which would be 1.20, not 1.35. for 8 days, the cost would be (8*0.30) = 2.40, which is what we have for y in the pair. Therefore, (8, 2.40) is the answer.

Hope this helps! :)

Answer:

The answer is (8, 2.40).

Suppose △FLX≅△ZAQ.

Which other congruency statements are correct?



Select each correct answer.

△LXF≅△AZQ

△LFX≅△AZQ
△FXL≅△ZQA
△XFL≅△QZA

Answers

In this question you got △FLX≅△ZAQ which mean:
F≅Z
L≅A
X≅Q

Then if you translate the left side of the option it would become like this.
△LXF = AQZ         ≅△AZQ  (false)
△LFX = AZQ        ≅△AZQ (true)
△FXL = ZQA        ≅△ZQA (true)
△XFL = QZA        ≅△QZA (true)

Which equation to solve the problemIt takes Zane m minutes to clean his room.  This is 35 minutes more that the 22 minutes it takes to walk the dog.  How long does it take to clean his room?

A. m-35=22
B. m+22=35
C. 35-m=22
D. m+35=22

Answers

The equation labeled ' A ' will lead you to the correct value of ' m ' .
I think the answer is A because 35 mins more that the 22 mins it takes to walk the dog so have to be 22+35

1. At a fundraiser breakfast, the bill for 3 glasses of orange juice and 5 pancake specials is $7.60, whereas the bill for 1 glass of orange juice and 2 pancake specials is $2.90. a. Write a system of 2 equations to model this problem. Let j stand for the price of a glass of juice and let p stand for the price of a pancake special. b. Use the substitution method to solve the system of equations. c. What would the bill be for 1 glass of orange juice and 1 pancake special?

Answers

a.
If:
j - the price of a glass of juice
p - the price of a pancake special
Then:
3j + 5p = 7.60
j + 2p = 2.90

b.
If:
j + 2p = 2.90
Then:
j = 2.90 - 2p
We can substite j in the first equation.
If:
3j + 5p = 7.60
j = 2.90 - 2p
Then: 
3×(2.90-2p) + 5p = 7.60
8.70 - 6p + 5p = 7.60
8.70 - p = 7.60
⇒ p = 8.70 - 7.60
⇒ p = 1.10

If:
j = 2.90 - 2p
p = 1.10
Then:
j = 2.90 - 2×1.10
j = 2.90 - 2.20
j = 0.70

Thus, the price of a glass of juice is $0.70 and the price of a pancake special is $1.10.

c.
If:
p = 1.10
j = 0.70
Then: 
j + p = 1.10 + 0.70 = 1.80

Thus, the bill for 1 glass of orange juice and 1 pancake special is $1.80.
