A tennis coach took his team out for lunch and bought 8 hamburgers and 5 fries for $24. The players were still hungry so the coa

g100num [7]

The cost of 1 hamburger is $ 2.5 and cost of 1 fries is $ 0.8

<h3><u>Solution:</u></h3>

Let "f" be the cost of 1 fries

Let "h" be the cost of 1 hamburger

<em><u>Given that, tennis coach took his team out for lunch and bought 8 hamburgers and 5 fries for $24</u></em>

8 x cost of 1 hamburger + 5 x cost of 1 fries = 24

$8 \times h + 5 \times f = 24$

8h + 5f = 24 -------- eqn 1

<em><u>The players were still hungry so the coach bought six more hamburgers and two more fries for $16.60</u></em>

6 x cost of 1 hamburger + 2 x cost of 1 fries = 16.60

$6 \times h + 2 \times f = 16.60$

6h + 2f = 16.60 ------ eqn 2

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

Multiply eqn 1 by 2

16h + 10f = 48 ------ eqn 3

Multiply eqn 2 by 5

30h + 10f = 83 -------- eqn 4

<em><u>Subtract eqn 3 from eqn 4</u></em>

30h + 10f = 83

16h + 10f = 48

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

14h = 35

Substitute h = 2.5 in eqn 1

8(2.5) + 5f = 24

20 + 5f = 24

5f = 4

Thus cost of 1 hamburger is $ 2.5 and cost of 1 fries is $ 0.8

Prove AED is equal to DEB. Do not use vertical angle theorem

Nastasia [14]

Answer:

Step-by-step explanation:

From the figure attached,

Given:

Lines AB and CD are intersecting each other at a point E.

To prove:

∠ACB ≅ ∠DEB

Statements Reasons

1). ∠AEC + ∠BEC = 180° 1). Linear pair theorem

2). ∠DEB + ∠BEC = 180° 2). Linear pair theorem

3). ∠AEC + ∠BEC = ∠DEB + ∠BEC 3). Transitive property of equality

4). ∠AEC = ∠DEB 4). Subtraction property of equality

Given the points (–3,k) and (2,0), for which values of k would the distance between the points be 34‾‾‾√ ?

galina1969 [7]

The distance between the points (–3,k) and (2, 0) exists k = ± 3.

How to estimate the distance between points (–3, k) and (2, 0)?

To calculate the distance between two points exists equal to

$d=\sqrt{(y 2-y 1)^{2}+(x 2-x 1)^{2}}$

we have (-3, k) and (2, 0)

$$&d=\sqrt{34}$

substitute, the values in the above equation, and we get

$$\sqrt{34} &=\sqrt{(0-k)^{2}+(2+3)^{2}} \\$

simplifying the above equation

$$\sqrt{34} &=\sqrt{(-k)^{2}+(5)^{2}} \\$

$$\sqrt{34} &=\sqrt{k^{2}+25}$

squared both sides

$$&34=k^{2}+25 \\$

$$&k^{2}=34-25 \\$

$$&k^{2}=9 \\$

k = ± 3

Therefore, the value of k = ± 3.
