Step-by-step explanation:
5(d - 68) = 85
Use distributive property
5*d - 68*5 = 85
5d - 340 = 85
Add 340to both sides
5d = 85 + 340
5d = 425
Divide both side by 5
d = 425/5
d = 85
Answer:
It's the same process, change 4 4/5 to an improper fraction = 24/5 then set up a proportion
4 bananas/(24/5) kg = 3 bananas/x kg take cross products
4x = 3 (24/5) = 72/5 divide by 4 (this is the same as multiplying by 1/4)
x = 72/20, change this to a mixed number = 3 12/20 = 3 3/5 kg

Answer: incomplete question
Find inverse
F(x)=5x-3/4
Ans: y/5+15/4=x
Step-by-step explanation: assuming f(x) to be y
Therefore y=5x-3/4
Y+3/4=5x
Dividing all through by 5 gives
Y/5+15/4=X
