The school that Trevon goes to selling tickets to the annual dance competition. On the first day of tickets sales the school sol
KiRa [710]

Answer:

  both kinds of tickets are $5 each

Step-by-step explanation:

Let s and c represent the dollar costs of a senior ticket and child ticket, respectively. The problem statement describes two relationships:

  12s + 5c = 85 . . . . . revenue from the first day of sales

  6s + 9c = 75 . . . . . . revenue from the second day of sales

Double the second equation and subtract the first to eliminate the s variable.

  2(6s +9c) -(12s +5c) = 2(75) -(85)

  13c = 65 . . . . . simplify

  65/13 = c = 5 . . . . . divide by the coefficient of c

Substitute this value into either equation. Let's use the second one.

  6s + 9·5 = 75

  6s = 30 . . . . . . . subtract 45

  30/6 = s = 5 . . . divide by the coefficient of s

The price of a senior ticket is $5; the price of a child ticket is $5.

Explain why this statement is true:<br> 7a +4 – 2a = 7a + (-20)+4
MAVERICK [17]

Answer:

This equation has one solution so given statement is true.

Step-by-step explanation:

7a +4 – 2a = 7a + (-20)+4

5a + 4 = 7a - 16

5a - 7a = -16 - 4

- 2a = - 20

a = 10

This equation has one solution so given statement is true.

You bike
Lyrx [107]
<h2>Answer:</h2>

<em>You will bike 30.2 miles in the seventh day according to the prediction.</em>

<h2>Explanation:</h2>

Here we have the following data, You bike

  • 5  miles the first day of your​ training,
  • 5.4 miles the second​ day,
  • 6.2 miles the third​ day, and
  • 7.8 miles the fourth day.

So we can know some facts:

  • From the first day to the second day the number of miles increases:

5.4-5=0.4mi

  • From the second day to the third day the number of miles increases:

6.2-5.4=0.8mi

  • From the third day to the fourth day the number of miles increases:

7.8-6.2=1.6mi

By taking a look at the pattern, we can see that each day you increases the number of miles by a factor of 2 compared to the previous day. So:

  • From the fourth day to the fifth day the number of miles increases:

x_{5}-7.8=3.2mi \\ \\ x_{5}=7.8+3.2=11mi, \ \text{Day 5}

  • From the fifth day to the sixth day the number of miles increases:

x_{6}-11=6.4mi \\ \\ x_{6}=6.4+11=17.4mi, \ \text{Day 6}

Finally:

  • From the sixth day to the seventh day the number of miles increases:

x_{7}-17.4=12.8mi \\ \\ x_{7}=12.8+17.4=30.2mi, \ \text{Day 7}
