BRAINLYEST AND 20 POINTS

For the given situation: Derek has $20 to spend on used books. Hardcover books cost $5 each and paperbacks cost $2 each. What equation in standard form determines the number x of hardcover books and the number y of paperback books he can buy? Select all the pairs that represent combinations of books that Derek can buy. Group of answer choices (2, 5) (0,10) (−2, 15) (3, 5/2) (1, 2/5)

Answers

Answer 1

Answer:

(0,10)

Step-by-step explanation:

All of  the other answers dont make sense or are false so it makes (0,10) the only correct answer.

Answer 2

The equation represents the situation is 5x + 2y ≤ 20 so pair (2,5) and (0,10) is possible thus options (A) and (B) is correct.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

As per the given,

Hardcover books cost $5 each and paperbacks cost $2 each.

The number of hardcover books is x while paperbacks are y

Thus,

Total cost = 5x + 2y

5x + 2y ≤ 20

The x and y is the whole number so they will never be negative or in fractions.

Therefore, The pair which satisfies the above expression is (2,5) and (0,10).

Hence "The equation represents the situation is 5x + 2y ≤ 20 so pair (2,5) and (0,10) is possible".

Answer:

x = 67°

Step-by-step explanation:

It's given that m║n.

Construction done: A line 't' parallel to the given lines 'm' and 'n'.

Since, m║t and a transversal line is intersecting these lines.

m∠a = 35° [Alternate interior angles]

m∠c = 180° - 148° [∠c and angle measuring 148° are the linear pair of angles]

       = 32°

n║t and a transversal line is intersecting these lines.

Since, ∠b ≅ ∠c [Alternate interior angles]

m∠a + m∠b = m∠x [Angle addition postulate]

x = 32° + 35°

x = 67°

Therefore, measure of angle x is 67°.

lin makes sparkling orange juice by mixing 3 liters of orange juice with 4 liters of soda water. Noah makes sparkling orange juice by mixing 4 liters of orange juice with 5 liters of soda water. How do the two mixtures compare in taste explain your reasoning

Answers

Answer:

Step-by-step explanation:

Lin makes sparkling OJ using the ratio

3:4. Meaning 3L orange juice for every 4L sparkling water.

Noah makes sparkling OJ using the ratio 4:5. Meaning 4L orange juice for 5L sparkling water.

If we said that they both used 12L of orange juice,

Lin would have to use 16L of sparkling water

Noah would have to use 15L of sparkling water

So for the same 12L of orange juice, Lin uses more sparkling water.

Therefore her sparkling OJ would be more diluted (less orange flavour since you added more water) and more bubbly than Noah's.

Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise. How much will she earn each hour after the raise?

Answers

Answer:

28.75

Step-by-step explanation:

We can do 15% of 25 which is 3.75. Add this on to 25, and get 28.75.

The amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

The raise = 15 % of 25 = 3.75

Total after raise = 25.00 + 3.75 = $28.7

Thus, the amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

A sandwich is 2 12 feet long. You decide to cut the sandwich into pieces that are 1 14 feet long. How many pieces will you cut?

Answers

Answer:

Im assuming you meant 2 1/2 and 1 1/4, so the answer would be 2 pieces

Step-by-step explanation:

2 1/2-1 1/4=1 1/4, so 2

Using the division operation, the number of pieces of sandwich that can be cut is 2

Given the Parameters :

Length of sandwich = 2.5 feets

Length per piece cut = 1.25 feets

The number of pieces that can be cut out of the sandwich can be calculated thus :

Length of sandwich ÷ Length per piece cut

Number of pieces = (2.5 ÷ 1.25) = 2

Therefore, there are 2 pieces of sandwich that can be cut.

What is the value of the x-intercept?
What is the value of the y-intercept?
Remember when finding the x-intercept you cover up the y (put 0 in for y) and solve for the x value.

Answers

Answer:

see below

Step-by-step explanation:

−x+y=−5

To find the x intercept, let y=0 and solve for x

-x +0 = -5

-x = -5

x=5

The x intercept is 5

To find the y intercept, let x=0 and solve for y

0 +y = -5

y = -5

The y intercept is -5
