Answer:

$24 for 5 hours. For t hours, 9+3t

Step-by-step explanation:

She has to pay $9 to enter + $3 * number or hours

Cost of parking for 3 hours

$9 + 5*$3 = 9+ 15 = $ 24

Cost of parking for t hours

$5 + t *$2 = 9 + 3t

Answer:

$24 for 5 hours. For <em>t</em> hours, 9+3<em>t</em>

Step-by-step explanation:

1. First set up the equation.

x= $9+$3h (we´ll let ¨<em>h</em>¨ represent every additional hour).

2. To find out how much she´ll have to spend after 5 hours, substitute 5 into the equation for <em>h</em>. Then solve.

x=9+3(5)\\x=9+15\\x=24     $24

3. Answer = $24.

Now to find the second answer.

1. Since we do not know the exact value of <em>t, </em>we can just leave it as <em>t.</em>

<em />x=9+3t

2. We cannot simplify this equation any further. Since this is how we find how much money for <em>t </em>hours, we leave it be.

Kaitlin, Tony, and Austin sent a total of 103 text messages over their cell phones during the weekend. Austin sent 4 times as ma
emmainna [20.7K]

The number of messages Kaitlyn, Tony and Austin sent are 13, 18 and 72 messages respectively.

<h3>How to write and solve equation?</h3>

let

  • Number of messages Kaitlyn sent = x
  • Number of messages Tony sent = x + 5
  • Number of messages Austin sent = 4(x + 5)
  • Total messages = 103

103 = x + (x + 5) + 4(x + 5)

103 = x + x + 5 + 4x + 20

103 = 6x + 25

103 - 25 = 6x

78 = 6x

x = 78/6

x = 13

Number of messages each sent:

Number of messages Kaitlyn sent = x

= 13 messages

Number of messages Tony sent = x + 5

= 13 + 5

= 18 messages

Number of messages Austin sent = 4(x + 5)

= 4(13 + 5)

= 4(18)

= 72 messages

Solve equation 3x-5y=7 5x-2y=-1 by elimination
kakasveta [241]

Answer:

x = -1, y = -2.

Step-by-step explanation:

Using the elimination method,

multiply the first eqn by 2 and the 2nd eqn by 5.

6x - 10y = 14

25x - 10y = -5

Subtract one of the new equations from the other

-19x = 19

x = -1

Sub x=-1 into the 2nd eqn

-5 - 2y = -1

y = -2

Hence x = -1, y = -2.
