Question

Evaluate r8+ 14s when
r =6 and s =1/4

Answer 1

51.5

Step-by-step explanation:

r8 + 14s

r = 6

s =
`\bold{(1)/(4) }`

Convert
`\bold{(1)/(4) }` to a decimal: 1 ÷ 4 = 0.25

Insert 6 for 'r' and 0.25 for 's' in the equation

6 · 8 + 14 · 0.25

48 + 14 · 0.25

14 · 0.25 = 3.5

48 + 3.5 = 51.5

What we can do here is to plug the given values into the expression.

8r+14s

8(6)+14(1/4)

Simplify.

48+3.5
