The correct option is B): "<span>Let x = 1st integer. Let x + 2 = 2nd integer.</span><span>"
Given that "The sum of two consecutive odd integers is 28."
Now the difference between two odd numbers is 2.
So this means that one odd number has to be greater than the other by 2.
Let the smaller number be 'X' therefore the bigger number will be 'x+2'
thus
x + (x+2) = 28
therefore,
x + x + 2 = 28
now we subtract "2" from both the sides
therefore,
2x = 26
now dividing throughout by 2 we get:
x = 13
therefore,
x + 2 = 13+2
= 15
therefore, the numbers are
13 AND 15</span>

hi
Step-by-step explanation:
What do you use Phone no. Hi what
Answer:
Step-by-step explanation:
step a system of two equations c = child ticket a = adult ticket
eq 1) 2c + 1a = 8.2 multiply by 2
eq 2) 3c + 2a = 14.1
I will multiply eq 1 times TWO and subtract eq 2 from eq 1a)
eq 1a) 4c + 2a = 16.4
eq 2) 3c + 2a = 14.1
subtract (4c - 3c) + (2a -2a) = 16.4 - 14.1
c + 0 = 2.3 euros for one child ticket
Now find the adult ticket price, plug 2.3 for c into eq 1)
eq 1) 2c + 1a = 8.2
eq 1) 2(2.3) + 1a = 8.2 solve for a
4.6 + a = 8.2 substract 4.6 from both sides
a = 8.2 - 4.6
= 3.6 euros for one adult ticket
double check using eq 2) we know c and a values
eq 2) 3c + 2a = 14.1
eq 2) 3(2.3) + 2(3.6) = 14.1
6.9 + 7.2 = 14.1
14.1 = 14.1
Vertex =(1,2). It’s is also the minimum of our parabola
Y-intercept (0,3)
Axis ps symmetry is x=1
I think 14 is B (idrk) and 15 is definitely C
