Final answer:
To find x in the equations, we isolate x on one side of the equation. Solving each equation step by step, we find x = 50 (in equation a), x = 26 (in equation b), and x = 256 (in equation c).
Step-by-step explanation:
To find x in the equations, we need to isolate x on one side of the equation. Let's solve each equation step by step:
a) 2485/x = 49R35
We can cross-multiply to get 2485 = x * 49R35. The R represents a repeating decimal. To remove the repeating decimal, we can multiply both sides by 100 to get 100 * 2485 = x * (49R35 * 100). This simplifies to 248500 = x * 4935. Finally, by dividing both sides by 4935, we find x = 50.
b) 1348/x = 5R148
Again, cross-multiply to get 1348 = x * 5R148. Multiply both sides by 100 to remove the repeating decimal and get 100 * 1348 = x * (5R148 * 100). This simplifies to 134800 = x * 5148. Divide both sides by 5148 to find x = 26.
c) 984/x = 3R84
Repeat the previous steps: cross-multiply to get 984 = x * 3R84, multiply both sides by 100 to remove the repeating decimal, simplify to 98400 = x * 384, and divide both sides by 384 to find x = 256.
