Hope this helps dude
Step-by-step explanation:
In part (d), we are shown how the sum of consecutive integers can be found. The sum is:
S = n (x + y) / 2
where n is the number of integers, x is the first integer, and y is the last integer.
We want to use this formula to find the sum of the numbers 101-110. We know there are 10 numbers between 101 and 110, so n = 10.
S = 10 (101 + 110) / 2
S = 1055
We used deductive reasoning to find the answer.
Answer:
x = 15/2
Step-by-step explanation:
Solve for x:
4 x + 12 = 42
Subtract 12 from both sides:
4 x + (12 - 12) = 42 - 12
12 - 12 = 0:
4 x = 42 - 12
42 - 12 = 30:
4 x = 30
Divide both sides of 4 x = 30 by 4:
(4 x)/4 = 30/4
4/4 = 1:
x = 30/4
The gcd of 30 and 4 is 2, so 30/4 = (2×15)/(2×2) = 2/2×15/2 = 15/2:
Answer: x = 15/2
therefore there are no solutions in real numbers.
