Just substitute in the number 3 for x then subtract 3 at both sides and youll have y=7
It's 18 it means 18 times 3 becomes 54 and that's how you get it
Set up an equation 20=k(0.4)....to find k divide 20 by 0.4
Answer:
The desired divisor is n = 21
Step-by-step explanation:
Let that number be n. Then:
-15/56 -5
---------- = ---------
n 6
Through cross-multiplication we get:
(-15/56)*6 = -5n, which reduces to:
(-15)(7) = -5n, or 3(7) = n
The desired divisor is n = 21
