Explanation

To divide 0.213 by 0.00213, we can use a calculator or perform the calculation manually:

0.213 ÷ 0.00213 = 100

So, the correct answer is: 100

Explanation

• To solve 3 × 8 + 38:
• First, calculate 3 × 8 = 24.
• Then, add 24 to 38
• 24 + 38 = 62
• So, the answer is 62.

Explanation

To find the value of y in the equation 3x+y=2, we can substitute the given value of x into the equation and solve for y.

1. Given value of x: x = 4.

2. Substitute the value of x into the equation: 3(4) + y = 2.

3. Simplify the equation: 12 + y = 2.

4. Solve for y by isolating the variable: y = 2 - 12.

5. Simplify the right side of the equation: y = -10.

Therefore, when the value of x is 4 in the equation 3x+y=2, the value of y is -10.

Explanation

The pattern follows: +12, +13, +14, +15, +16

74 + 16 = 90

Explanation

To solve for X, subtract 8 from both sides of the equation:

3X + 8 - 8 = 20 - 8

3X = 12

Next, divide both sides by 3:

3X / 3 = 12 / 3

X = 4

So, the value of X is 4!

Explanation

• When you divide 185 by 5:
• 185 ÷ 5 = 37
• So, the answer is 37.

Explanation

(4 x 3 + 5 x 6) / (18 x 2 – 22)

= (12 + 30) / (36 - 22)

= 42 / 14

= 3

Explanation

To find 45% of 225, multiply 225 by 0.45.

225 × 0.45 = 101.25

So, 45% of 225 is 101.25.

Explanation

To find the answer, we need to calculate the percentage step by step:

• 20% of 30% = (20/100) × (30/100) = 6/100 = 6%
• 10% of 6% = (10/100) × (6/100) = 0.6/100 = 0.6%

So, the correct answer is: 0.6%
