Answer:
Step-by-step explanation:
The equations would look like this:
x + 8x + x + 100 = 840
Combine like terms.
10x + 100 = 840
Subtract 100 from each side.
10x = 740
Divide both sides by 10.
x = 74
So, that makes one of the numbers 74.
Now, we're gonna substitute 74 into 8(x) to find the second number.
8(74) = 592
So, the next number is 592.
592 + 74 = 666
840 - 666 = 174
So, the numbers are 74, 592, and 174
If you'd like to check the answer, plug the numbers back into the equation:
74 + 8(74) + 74 + 100 =
840.
Answer:
(5.83, 2.11, 2)
Step-by-step explanation:
To convert from rectangular coordinates to cylindrical coordinates we use
Therefore (-3,5,2):
So the coordinates are (5.83, 2.11, 2)
4*10+3+800000+5000=805043
12000 - 2900 = 9100
9100 / 36 = 252.77.....about 253 per month
Step-by-step explanation:
x × x = 49 there are two values for x
1) 7 because 7 × 7 = 49
2) -7 because -7 × -7 = 49 the square value for negative numbers is positive.
