Answer:
The possible combinations of two letters is 12
Step-by-step explanation:
Here, we want to count the possible combinations of two letters
Now, for the first letter any point in time, we have 4 letters to pick from,
For the second letter we have 3 letters to pick from
So therefore, we have the possible combinations as;
4 * 3 = 12
Answer:
Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation
x + 2x + 2x + 30 = 380
collect like terms
5x = 350
x = 70
the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm
Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct
Step-by-step explanation:
