Question

What is 7(f-1)=45

Answer 1

7f-7=45 then 7f=52 divide 7 and you get a decimal 7.43

Answer 2

\[7(f-1)=45\]
distribute the 7:\[7f-7=45\]add the 7:\[7f=52\]divide by 7:\[f={52\over7}\]

Answer 3

or in decimal form: \(7.4285714...\)

Answer 4

which would round it up to \(f\approx7.439\)

Answer 5

distribute the 7
so,
7f - 7 = 45
add 7 over
7f = 52
divide by 7
so its f = 52/7
