Answer: jackson is 12
explanation:
let the age be represented by x
jackson is 2 times older than shelly so
2x is jackson’s age and x is shelly’s age
since the sum of their ages is 18 then:
2x + x = 18
solve:
3x = 18 ➔ divide by 3 on both sides
x = 6
so now we know shelly is 6
jackson is 2 times older than her so:
2(6) = 12
Answer:
three consecutive odd integers are.

Step-by-step explanation:
Let x be the first term of odd integer,
Therefore, the second consecutive odd integers = 
Similarly, the third consecutive odd integers = 
Given:
The sum of the first term and second term is 344.
first term + second term = 344
Here first term is x and second term is
.





Therefore, the first odd integers is 171.
And the second consecutive odd integers = 
Similarly, the third consecutive odd integers = 
Answer:126 pounds
Step-by-step explanation:
The ratio from dolphins to pound of fish in one day is 1:7
So you have to multiply the ratio on both sides by 18
So you will get 18:126

Answer:
C. x²+12x+36
Step-by-step explanation:
Since a square's area is figures out with
and since the length is x+6, then we get:
(x+6)²=
(x+6)(x+6)=
<em>Use </em><em>FOIL</em><em> method.</em>
First: x²
Outer: 36
Inner: 6x
Last: 6x
x²+36+6x+6x=
x²+12x+36
The answer that fits is C. x²+12x+36.
