Ihave either 1 or 2 attempts to get it

You just have to make equal fractions, so if c = 4 that means = so cross multiply to get 7a = 20; divide both sides by 7 to get a = 2.86 and do the same with the other ones

If c = 11 then = cross multiply to get 7a = 55; divide both sides by 7 to get a = 7.86 and so on

The answer is true to the other question

Hope this helps :)

x = 8

y = 14

Step-by-step explanation:

2x + 6 = 4x - 10 (Corresponding angles so they're equal)

2x - 4x = -10 - 6

-2x = -16

x = 8

2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)

2(8) + 6 + 13y - 24 = 180

16 + 6 + 13y - 24 = 180

13y - 2 = 180

13y = 182

y = 14
