The sum of three consecutive number is 633 ,find the numbers
chubhunter [2.5K]

Answer:

210, 211, 212

Step-by-step explanation:

If we denote the first number as x, then the second number can be written as x + 1 and the third number as x + 2.

The equation is:

x + (x + 1) + (x + 2) = 633

3x + 3 = 633

3x = 633 - 3

3x = 630

x = 210

So the three consecutive numbers we're looking for are: 210, 211, 212

If one kilogram is 2.2 pounds how many kilograms would it make for 11 pounds
Mila [183]

Answer:

5 kg

Step-by-step explanation:

To solve this problem, we can use the rule of three.

In fact, we know that:

- 1 kilogram is equivalent to 2.2 pounds

- The ratio between the mass in kilograms and in pounds is constant for every value of the mass

- Therefore, the mass in kilograms corresponding to 11 pounds can be found by writing the following equation:

\frac{1 kg}{2.2 p}=\frac{x}{11 p}

Where

x is the mass in kilograms corresponding to 11 pounds.

Solving the equation for x, we find:

x=\frac{(11p)(1kg)}{2.2p}=5 kg

what is the equation in point-slope form of the line passing through (4, 0) and (2, 6)? y = 4x − 2 y = 2x − 4 y = −3(x − 4) y =
Brilliant_brown [7]
Equation in point slope form is given by y - y1 = m(x - x1); where m = (y2 - y1)/(x2 - x1).

y - 0 = (6 - 0)/(2 - 4) (x - 4)
y = 6/-2 (x - 4)
y = -3(x - 4)
