So first of all we can't start by changing them both into improper fractions
So it would be:
5/2 divided by 13/8
From there you would do 5/2 * 8/13 which could convert to
5/1 * 4/13 which would be 20/13
Answer:
<h3> 10,450</h3>
Step-by-step explanation:
21-13=8 and 29-21=8
So this is aritmetic series where a₁ = 13, and r = 8
Sum of the first n terms:
![S_n=\dfrac{a_1+a_n}{2}\cdot n=\dfrac{a_1+a_1+(n-1)r}{2}\cdot n=\dfrac{2a_1+(n-1)r}{2}\cdot n\\\\\\S_{50}=\dfrac{2\cdot13+(50-1)\cdot8}{2}\cdot50=(13+49\cdot4)\cdot 50=10,450](https://tex.z-dn.net/?f=S_n%3D%5Cdfrac%7Ba_1%2Ba_n%7D%7B2%7D%5Ccdot%20n%3D%5Cdfrac%7Ba_1%2Ba_1%2B%28n-1%29r%7D%7B2%7D%5Ccdot%20n%3D%5Cdfrac%7B2a_1%2B%28n-1%29r%7D%7B2%7D%5Ccdot%20n%5C%5C%5C%5C%5C%5CS_%7B50%7D%3D%5Cdfrac%7B2%5Ccdot13%2B%2850-1%29%5Ccdot8%7D%7B2%7D%5Ccdot50%3D%2813%2B49%5Ccdot4%29%5Ccdot%2050%3D10%2C450)
For question a) you can do 2 x 7 sine their are 7 days in a week 2 x 7 = 19 so by the end of each week Carmen has $19. in 10 weeks she will have $20 dollars. if in 10 weeks she has $20 wait if it is time two there can't be 35 try 17 cause that's closes so in 17 she will have $36. Same thing Lilly starts with $10 each week she gets $1 a week so 1 x 7 = 7 and since she started with $ 10 she has $17 Lilly must earn 19 dollars to be equal with Carmen. Hope this helps
