K added to 10 gives you 4 times the value of K.
If you wanted to solve the expression:
Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k
If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.
We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k
Distance = speed x time
Speed= 520÷10=52
52mi/hour
Answer:
m = 80 - 58h
Step-by-step explanation:
Expenses:
$120 for flours
$58h for salaries
Revenue:
$200 from sales of flours
m = 200 - 120 - 58h
m = 80 - 58h
