Odd numbers are represented as 2n+1 where 2 is a natural number ( negative and possitive whole numbers)
consecutive odd numbers are 2 away from each other so 3 consecutive odd numbers would be
(2n+1),(2n+1+2),(2n+1+2+2)
the all add to -15 so they must all be negative
2n+1+2n+1+2+2n+1+2+2=-15
add like terms
6n+9=-15
subtract 9 from both sides
6n=-24
divide both sides by 6
n=-4
subsitute
first number=2n+1=2(-4)+1=-8+1=-7
second number=2n+1+2=2(-4)+3=-8+3=-5
third number=2n+1+2+2=-8+5=-3
the numbers are -7,-5, -3
the answe ris B
Here is the solution for this question.
Are you providing steps...or just want us to solving showing you what to do?
.................................
3 + 4d - 14 = 15 - 5d - 4d
First, combine like terms on each side of the equals.
-11 + 4d = 15 - 9d
now, move the -11 over to the right by addition
4d = 26 - 9d
now, move the -9d over to the left by addition
13d = 26
now, divide each side by 13
d = 2
Answer:
108 boys and 81 girls
Step-by-step explanation:
If B is the number of boys and G is the number of girls, then:
B + G = 189
B − G = 27
To solve, use substitution or elimination. In this case, I recommend elimination. Add the equations together:
2B = 216
B = 108
Therefore:
G = 81
So there are 108 boys and 81 girls.
Answer:
3 3/4 x 2 10/11 = 120/11 which is equal to 10 10/11 which is the simplified answer
Step-by-step explanation:
make them inproper so you have 15/4 and 32/11 which the product is 120/11 which you can make a proper fraction which is 10 10/11
