Answer:
the numbers are 7 and 11
Step-by-step explanation:
If you add the smaller to the sum of numbers, you have the sum of the greater and twice the smaller. That is ...
18 + smaller = 25
smaller = 25 -18 = 7
larger = 18 -7 = 11
The two numbers are 7 and 11.
_____
If you like, you can write two equations. Let x and y represent the smaller and larger numbers, respectively.
x + y = 18
2x + y = 25
Subtract the first equation from the second:
(2x +y) -(x +y) = (25) -(18)
x = 7
y = 18-x = 18-7 = 11
The numbers are 7 and 11.
Given the sequence 5, 6, 7, 8, ....., where x = 1, 2, 3, 4, ...., what is the first term in the sequence?
wel
The first term in the sequence is 5.
<u>Step-by-step explanation</u>:
The sequence is 5,6,7,8,.....
- The first term = 5
- The second term = 6
- The third term = 7
where x= 1,2,3,4,...
The sequence follows the pattern (x+4).
- For x=1, then (1+4) = 5 which is the first term of the sequence.
Similarly,
- For x=2, then (2+4) = 6 which is the second term of the sequence and the sequence follows the same pattern.
Answer:
x = -3.5 ± √17/2
or
x = -1.44, -5,56 to the nearest hundredth.
Step-by-step explanation:
x^2 = –7x – 8
x^2 + 7x + 8 = 0
Using the quadratic formula:
x = [-7 ± √(7^2 - 4*1*8)] / 2
x = -3.5 ± √17/2
