Answer:

Step-by-step explanation:

Take an easier number.  Suppose you owe your mother = 10 dollars and your father 15. Which one is the bigger debt? Isn't it your father.? So how do you represent the two debts.

Father = - 15

Mother = - 10

Which number is bigger? - 10. Remember the question is bigger. You would rather own just 10 dollars.

So which number is "larger"?

Isn't it -4488. If it was money and you owed it, would it be the debt you would rather have than -4820

Isabella went into a movie theater and bought 3 drinks and 10 pretzels, costing a total of $54.50. Jason went into the same movi
ruslelena [56]

The price of 1 drink is $ 4 and price of 1 pretzel is $ 4.25

<em><u>Solution:</u></em>

Let d" be the price of 1 drink

Let "p" be the price of 1 pretzel

Given that, Isabella went into a movie theater and bought 3 drinks and 10 pretzels, costing a total of $54.50

<em><u>Therefore, we can frame a equation as,</u></em>

3 x price of 1 drink + 10 x price of 1 pretzel = 54.50

3 \times d + 10 \times p = 54.50

3d + 10p = 54.5 ---------- eqn 1

Jason went into the same movie theater and bought 9 drinks and 5 pretzels, costing a total of $57.25

9 x price of 1 drink + 5 x price of 1 pretzel = 57.25

9 \times d + 5 \times p = 57.25

9d + 5p = 57.25 ---------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

Multiply eqn 1 by 3

9d + 30p = 163.5 ----- eqn 3

<em><u>Subtract eqn 2 from eqn 3</u></em>

9d + 30p = 163.5

9d + 5p = 57.25

( - ) -----------------------

25p = 106.25

p = 4.25

<em><u>Substitute p = 4.25 in eqn 1</u></em>

3d + 10(4.25) = 54.5

3d + 42.5 = 54.5

3d = 54.5 - 42.5

3d = 12

d = 4

Thus price of 1 drink is $ 4 and price of 1 pretzel is $ 4.25

The product of nine and a number is added to six the result is 24 what is the number
Andru [333]
Hello!

We can make an equation based on what we know

The product of 9 and a number is

9 * x

Added to six

9 * x + 6

Gives the result of 24

9 * x + 6 = 24

Now you solve it algebraically

Subtract 6 from both sides

9 * x = 18

Divide both sides by 9

x = 2

The answer is 2

Hope this helps!

Find the measure of angle b if angle a is 22 degrees and the whole angle is 300 degrees
Dima020 [189]

Answer:

a  = 278^{\circ}

Step-by-step explanation:

Given

b = 22^{\circ}

Whole\ Angle = 300^{\circ}

Required

Find the measure of a

Since there is no diagram to support the question, we'll assume that:

a + b = Whole\ Angle

This gives:

a + 22^{\circ} = 300^{\circ}

Subtract 22 from both sides

a + 22^{\circ}-22^{\circ} = 300^{\circ}-22^{\circ}

a  = 300^{\circ}-22^{\circ}

a  = 278^{\circ}
