Answer:
74 °
Step-by-step explanation:
the sum of every angle from a triangle is 180
so to find b is add 80 with 26 which is 106
then subtract 180 with 106
the final answer is 74

Answer:
383 children and 361 adults
Step-by-step explanation:
Let's say there are a adults and c children. Since the total number of people was 744, we can write:
a + c = 744
We also know that children's prices are $1.75 per child and adults' prices are $2 per adult. Since the total is $1392.25, we can write:
1.75c + 2a = 1392.25
Now we have a system of linear equations:
a + c = 744
1.75c + 2a = 1392.25
Multiply the first equation by 2:
2 * (a + c = 744) ⇒ 2a + 2c = 1488
Now subtract the second equation from this one:
2a + 2c = 1488
- 2a + 1.75c = 1392.25
___________________
0a + 0.25c = 95.75
c = 383
Plug this in to find a:
a + c = 744
a + 383 = 744
a = 361
There were 383 children and 361 adults.
Answer:
the answer is x=2
Step-by-step explanation
First of all put all x in one side of equation and number to the other side
Bare in mind that when we move from one side of equation to another positive integers become negative and negative integers become positive
5x-6=2x
5x-2x=6 here we moved 2x to other side of equation thus, it become -2x, and -6 was moved to other side of equation thus it become 6
3x=6 we subtracted from 5x-2x and found 3x since we can subtract the variables having the same element i this case that is x
x=6/3 we divided 6/3 in order to find the value of x. please note that 3x means 3*x
x=2
