Explanation

Average of 10 values = 200

Total sum = Average × Number of values

= 200 × 10

= 2000

Sum of 9 values = 1850

10th value = 2000 − 1850 = 150

Explanation

Let the number be x.

3% of x = 60

3/100 x X = 60

X= 60 x 1000/3

$$x = frac{60 times 100}{3}$$ x=2000​

Explanation

Explanation

Look at how much it increases each time:

Term 1: x  

Term 2: x + 6 → increased by 6  

Term 3: x + 18 → increased by 12  

Pattern of increases: 6, 12, ...  

It goes up by 6 each time. So next increase = 18

Term 4 = Term 3 + 18 = (x + 18) + 18 = x + 36

If we take x = 18, then the terms are 18, 24, 36, 54

Explanation

Put x = -2 and y = 3 in x³y² + x²y  

x³ = (-2)³ = -8  

x² = (-2)² = 4  

y² = 3² = 9  

So x³y² = -8 x 9 = -72  

And x²y = 4 x 3 = 12  

Now add both: -72 + 12 = -60

Explanation

The equation |-x| = 0 simplifies to x = 0 since the absolute value of any number is zero only when the number itself is zero.

Therefore, the solution set contains only {0}.

Explanation

First find 3/4 of 92  

3/4 of 92 = 92 divided by 4 = 23  

23 times 3 = 69  

Then add 13  

69 + 13 = 82
