Answer:
adults=31, children = 108
Step-by-step explanation:
a + c = 139 equation 1
10a + 8c = 1174 equation 2
a=139-c isolate a from equation 1
10(139-c) + 8c = 1174 substitute a value into equation 2
1390-10c + 8c = 1174
-2c = -216
c = 108
use value of c in either equation to find value of a
a + c = 139
a + 108 =139
a = 31
Answer:
2000
Step-by-step explanation:
One way to do this is to add half of a thousand, then zero all digits to the right of the thousands place.
2371 +500 = 2871
With digits zeroed, this is ...
2000
__
<em>Additional comment</em>
The traditional instruction is to look at the digit in the place to the right of the thousands place. (It is 3.) If it is 5 or more, you increase the number by 1 in the place you're rounding to. (No increase is needed.) Then you set all digits to the right of the thousands place to zero.
2371 rounds to 2000
Answer:
width = x - 5
Step-by-step explanation:
x² - 25 = x + 5 × width

x - 5 = width
width = x - 5
