Answer:
S=H+2
Step-by-step explanation:
OK, so hailey is the variable H. And she is 2 years younger than her sister.
What is the age of her sister?
So we know it has to be, hailey's age + something? = age of her sister.
what is that +something? it's the number "2 years younger" so hailey's age; which is h, plus 2 is equal to her sister's age.
H+2=S
OK, why do we need to add 2? instead of minus two? Because hailey is 2 years younger than her sister, so you want hailey's age. If you were to minus 2, you'd be thinking that hailey is OLDER than her sister. Because if you want to her sister's age, you would have to SUBTRACT 2 because you are OLDER than her. So if you are younger than the sister, you would add to get your sister's age.

P= 2
T=6
3) 252$
Step-by-step explanation:
1) set up your equation 3/8p=6/8 then divide 3/8 from both sides (remember when you divide fractions you would multiply by the reciprocal so 3/8 x 8/6. Also make sure you simplify)
2) Do the same here. 38/7 divided by 19/21
3) Turn the fraction into an improper fraction then multiply 126 by that amount (3/6)
110 because avg speed is total distance over total time
Answer:
25 boxes.
Step-by-step explanation:
We have the inequality:
190 + 60x ≤ 1740 where x = the number of boxes of books.
60x ≤ 1740 - 190
60x ≤ 1550
x ≤ 25.83.
D=25m+50
D=(25)(8)+50
D=200+50
D=250
There will be $250 after 8 months.
