How do i evaluate 3/7r+5/8s when r=14 and s=8

Mathematics
1 answer:

Answer:

11

Step-by-step explanation:

3/7r + 5/8s

r = 14

s = 8

3/7 x 14 + 5/8 x 8

3/7 x 14 = 6

5/8 x 8 = 5

6 + 5 = 11

ok so it's like the 3/7 and 5/8 are fractions so you just multiply each one by the number their next you which in this case is r and s so it's like you're just multiplying a fraction and a number. does that make since?

Whats the area? thanks!
AlladinOne [14]
The area is 279. You do 11×19 to get the bottom portion. That will give you 209. Then for the top subtract 11 from 18 to get that side length and then do 7×10. With that you will get 70 and then you add 209 to that. 209+70=279.

Wheel world sold 875 cars last year if the sales this year are 120% of sales last year how many cars will they sell this year
inn [45]

okay so first you wanna turn that 120% into a decimal and the decimal form of that would be 1.2 or 1.20

Secondly you want to multiply 875 by the 1.2

875*1.2 = 1050

So if they sell 120% of last years sales they will sell 1050 cars this year.

Hope this helped :)
