Y=2x-2.5 find x if y=10​

x = 6.25

Step-by-step explanation:

y = 2x - 2.5

10 = 2x - 2.5

+ 2.5     + 2.5

12.5 = 2x

   2     2

6.25 = x

x is equal to 5

Step-by-step explanation:

10=2x-2.5 (to find x we are to make the equation equal to x)

10+2.5=2x-2.5+2.5 (eliminate the 2.5 on the side with the x by adding 2.5 on both sides)

12.5/2=2x/2 (now divide each side by 2 to make the equation equal to x)

6.25=x or x=6.25

6^2 + 8^2 = c^2

100 = C^2

c = 10
