let's say the two numbers are x and x + 9. so we know x + x + 9 = 21, so 2x + 9 = 21. subtract 9 from both dies to get 12 = 2x. divide both sides by 2 to get x = 6. so your two numbers are 6 and 15.
What we know: Lucy's snake eat's 2 mice a week.
To find the answer, you'll have to multiply 2 by 6.
So, since Lucy's snake eats 2 mice a week for 6 weeks.
To find the amount of mice her snake has eaten in the past 6 weeks you'll have to multiply 2 and 6.
2x6=?
------------------------------------------------------------------
The first week the snake ate 2 mice.
The second week the snake ate 2 mice.
The third week the snake ate 2 mice.
The fourth week the snake ate 2 mice.
The fifth week the snake ate 2 mice.
The sixth week the snake ate 2 mice.
Your answer would be: 12
Answer:
Step-by-step explanation:
5/8 +1/n = 7/8
1/n= -5/8 +7/8
1/n = 2/8
1/n= 1/2
then you would try to get n by itself
by dividing n/1 to 1/n and 1/2
