Hannah is 2 times her sister’s age. the sum of their ages is no more than 18 years. 1) write an inequality that can be used to represent this situation. 2) using the inequality you just found, solve it to find the oldest age hannah's sister can be.

1)

2) 6 years old

Step-by-step explanation:

Let Hannah's age be and her sister's age be

It means

It means the sum is LESS THAN or EQUAL TO 18. So we can write:

1. We can substitute first equation into second equation to get our desired inequality of the situation. Thus,

2. To find MAXIMUM age of Hannah's sister, let's further simplify the inequality from number 1. So,

Hence, Hannah's sister's age is LESS THAN OR EQUAL TO 6. So maximum age of her sister is 6.

i think it is x = 1.2

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
