The units of the subway map at the right are in miles. Suppose the routes between stations are straight, find the distance you w
vova2212 [387]

Answer:

Distance between 2 stations= 8.94 miles

Step-by-step explanation:

The coordinates of Symphony Station is given by:

Symphony Station: (x₁ , y₁) : (1,2)

The coordinates of Elm station is given by:

Elm Station: (x₂ ,y₂) : (-3,-6)

We know that the distance formula can be used to find distance between these 2 points. Distance formula is given as

d= √((x₂ - x₁)² + (y₂ - y₁) ²)

Substitute values

d= √((-3 - 1)² + (-6 - 2) ²)

d= √((-4)²+(-8)²)

d= √(16+64)

d=√80

d= 8.94 miles

Raymond just got done jumping at super bounce trampoline center. The total cost of his session was $43.25. He had to pay a $7 en
fgiga [73]

1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.

Step-by-step explanation:

Given,

Total cost for session = $43.25

Entrance fee = $7

Charges per minute = $1.25

Let,

t be the number of minutes raymond was on Trampoline

Total cost for session = entrance fee + Charges per minute * No. of minutes

43.25=7+1.25*t\\1.25t+7=43.25

1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.

3(-X+4)=7x-8. Yeahhhh...
katovenus [111]

Hey there!☺

Answer:\boxed{x=2}

Explanation:

3(-x+4)=7x-8

Let's start by simplifying both sides. First, we distribute.

(3)(-x)+(3)(4)=7x+-8

-3x+12=7x+-8

-3x+12=7x-8

Now let's subtract 7x from both sides.

-3x+12-7x=7x-8-7x\\-10x+12=-8

Now we will subtract 12 from both sides.

-10x+12-12=-8-12\\-10x=-20

In our last/final step, we will divide both sides by -10.

\frac{-10x}{-10}=\frac{-20}{-10}

Now simplify -20/-10.

-20/-10=2

x=2

Hope this helps!

A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 t
defon

Answer:

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

Step-by-step explanation:

Let

Kelly's portion = x

Greg's portion = 2x

Joe's portion = 4x - 1.50

Total bill = $114.00

Total bill = Kelly's portion + Greg's portion + Joe's portion

114 = x + 2x + (4x - 1.50)

114 = 3x + 4x - 1.50

114 = 7x - 1.50

Add 1.50 to both sides

114 + 1.50 = 7x - 1.50 + 1.50

115.5 = 7x

Divide both sides by 7

x = 115.5 / 7

= 16.5

x = $16.5

Kelly's portion = x

x = $16.5

Greg's portion = 2x

= 2 × 16.5

= $33

Joe's portion = 4x - 1.50

= 4(16.5) - 1.50

= 66 - 1.50

= $64.5

Therefore,

Kelly owes $16.5

Greg owes $33

Joe owes $64.5
