5/4 as a decimal is 1.25 Hope this helped! :)
A)
3t = 7k/13 - 17
3t + 17 = 7k/13
13*(3t + 17) = 7k
7k = 13*(3t + 17)
7k = 39t + 221
k = (39t + 221) / 7
b)
7k = 4k/3t - 11t
11t = 4k/3t - 7k LCM = 3t
11t = (4k - 21kt) / 3t
11t*3t = (4k - 21kt)
33t² = k(4 - 21t)
33t² /(4 - 21t) = k
k = 33t² /(4 - 21t)
I hope this helps.
Its the table on the bottom left
For each increase of 1 of x y increases by 0.5 so its linear
16/155 = n
explanation
A linear equation is an equation of a straight line. To solve linear equations, it is important to keep the following key concepts in mind:
Maintain balance of the equation by applying the same operations to both sides of an equation
Isolate for the variable by collecting like terms
Use inverse operations to rearrange an equation
to show your work
-8/ 5 = -31/2 • n
- 8/5 = -31n/2
2(-8/5) = 2 • -31/n
-16/5 = -31n
-16/5 / -31 = -31n/31
16/155 = n
