210- 30= 180 which is what she has left to pay after the down payment.
15x12= 180
So, if Adela pays 15 dollars a week it would take her 12 weeks to complete her layaway.
Hope this helped!
Call your unknown number x. The reciprocal would be1/xYou are supposed to add your unknown number to 8 times its reciprocal, orx+8(1/x)This is all supposed to equal 6, so you havex+8/x=6
Solve for x to get your number.
n + 8(1/n) = 6n^2 + 8 = 6nn^2 - 6n + 8 = 0(n - 4)(n - 2) = 0n = 2, 4
So 2 and 4 both are answers in my opinion.
Answer:
5⁄18 < x
Step-by-step explanation:
Start by adding like-terms [⅓ and 2⁄9] with 9 being the Least Common Denominator [LCD]. Since 2⁄9 already has a 9 in the denominator, it does not get touched, so in order to make ⅓ a denominator of 9, we simply multiply both terms by 3, to get 3⁄9. So, adding that to 2⁄9 gives you 5⁄9, also giving you <em>5⁄9</em><em> </em><em>+</em><em> </em><em>x</em><em> </em><em>></em><em> </em><em>⅚.</em><em> </em>Now, we have to find the LCD again because we have two unlike fractions. Now, our Least Common Denominator is 18, so multiply both terms in ⅚ by 3 [15⁄18] and multiply both terms in 5⁄9 by 2 [10⁄18]. Now you have two like fractions to work with, and you can clearly see that your answer is <em>x</em><em> </em><em>></em><em> </em>5⁄18. Although the answer is written in reverse, it is still the same concept.
