the first and third equation
Step-by-step explanation:
when you divide 1/4 by 5, you get 1/20. dividing 1/4 by 5 is also the same as multiplying 1/4 by 1/5.
First we put the sentence into a function
9/10 * x + 6= 51Well then we solve<span>.</span><span>9/10* x= 51-6
9/10*x= 45
(<span>for</span> me is easier to make the fraction into a decimal...)
0.9*x= 45
x=45/0.9
x= 50
We check
9/10 * 50 + 6= 51
45+6=51
51=51
So the answer is x= 50</span>
