Equation-> 2x-3=x+12
x= 15

Bisector means it cuts it in half so angleABD and angleDBC are equal hence the equation of 2x-3= x+12

Add 3 both sides
2x=x+15
Subtract x both sides
X=15

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

Left Witch needs 3.25 gallons of "Toe of Frog" in her potion. If she can get half a gallon for $2.50, how much will she spend

Sladkaya [172]

Answer:

$16.25

Step-by-step explanation:

Half a gallon for $2.50 is the same as a quarter a gallon for $1.25.

If she needs 3.25 gallons, which is 13 quarters, we do $1.25 * 13 = $16.25.

Therefore, she will spend $16.25.

What is 30x pulse 80x

nataly862011 [7]

It would be 110x because they are like units, so they can be added together. Really, you are just doing 80 plus 30, and then adding an x on the end.

Please help! Thank you if you do :)

Kruka [31]

Step-by-step explanation:

A(-5,1) and B(0,4)

$m \: = \: \frac{y2 - y1}{x2 - x1}$

X1=0 , Y1=4 X2= -5 , Y2=1

$m \: = \: \frac{3 }{5}$

$y - y1 = m(x - x1)$

y - 4 = ⅗(x-0) ==> y - 4 = ⅗ X ==> y = ⅗ X + 4

<u>C</u> is the answer

How do I find the value of X ???

aleksandr82 [10.1K]

To solve for the value of x, you can simply add all of the values and expressions together and make it equal to 180 degrees, since the sum of all angles in a triangle add up to this amount.

Then we can solve for X, by algebra.
