Convert these amounts so they have the same units then express each pair as a ratio in its simplest form A) 5 days to 3 weeks and more l will tell yall once y'all ask pls hell ​

5:21

Step-by-step explanation:

To express the pairs in the same unit, 3 weeks has to be converted to days

7 days = 1 week

3 weeks = 3 x 7 = 21 days

the ratio can now be expressed as :

5 : 21

5:21 is already in its simplest form

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

ik how do do this just give me a few minutes and i will give it to
