Mathematics
1 answer:
nikklg [1K]2 years ago
5 0

Answer:

x = 13

Step-by-step explanation:

Sum or interior angles of a triangle is 180,

6x + 19 + 5x - 15 + 3x - 6 = 180

6x + 5x + 3x + 19 - 15 - 6 = 180

14x + 19 - 21 = 180

14x - 2 = 180

14x = 180 + 2

14x = 182

x = 182 / 14

x = 13

if the morning temperature started at -7 celsius but warmed during the day to 24 celsius . What is the temperature change
Murrr4er [49]

Answer:

31° change

Step-by-step explanation:

If we want to find the change between two numbers, we need to imagine it like a number line.

<-------------0------------->

Let's plot -7 and 24 on this number line.

<-----------7--0------------24>

If we want to get from -7 to 0, we increase by 7. To get from 0 to 24, we increase by 24.

So the total change is 7 + 24 = 31.

Hope this helped!

Twenty one children and three teachers went to the movies. The total bill was $105. The price for
MrRissso [65]

Answer:

c = price of child ticket = $4.25

a = price of adult ticket = $4.25 + $1.00 = $5.25

Step-by-step explanation:

A child ticket costs c and an adult ticket costs a = c + 1.

21 children pay c dollars each for admission, and

3 teachers pay c + 1 dollars each for admission.

Thus,

21c + 3(c + 1) = $105, and

21c + 3c + 3 = $105, so that:

24c = $102

c = price of child ticket = $4.25

a = price of adult ticket = $4.25 + $1.00 = $5.25
