3x minus one over five times the quantity 10x plus 5 equals 6 step 1: 3x – 2x – 1 = 6 step 2: x – 1 = 6 step 3: x – 1 – 1 = 6 – 1 step 4: x = 5 in which step was the error made and why?

The error was made in third step, because in this step 1 is subtracted instead of adding.

Step-by-step explanation:

Given equation,

3x minus one over five times the quantity 10x plus 5 equals 6

Step 1 : Apply distributive property on the left side,

Step 2 : By subtraction property on the left side,

Step 3 : Adding 1 on the both sides ( for isolating x on left side )

Step 4 : Combine the like terms,

Hence, by the above explanation it is clear that there was an error in third step,

Reason : 1 is subtracted instead of adding.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

the answer is 18 units because there are 18 small cubes inside the rectangle
