For this problem,we use the Fundamental Counting Principle. You know that there are 7 digits in a number. In this principle, you have to multiply the possible numbers for every digit. If the first number cannot be zero, then there are 9 possible numbers. So, the value for the first digit is 9. The second digit could be any number but less of 1 because it was used in the 1st digit. So, that would be 10 - 1 = 9. The third digit must be the value in the second digit less than 1. That would be 9 - 1 = 8. And so on and so forth. The solution would be:
9×9×8×7×6×5×4 = 544,320 7-digit numbers
Answer:
x+2
Step-by-step explanation:
i put mi x as one so
....that how i get my anwser
The equation would be 3(x + 5)
Allison can make 4 fruit parfaits.
Since one parfait requires 1/8 cup of yogurt, add:
1/8 + 1/8 + 1/8 + 1/8
They all share a common denominator, so:
1/8 + 1/8 +1/8 + 1/8 = 4/8
Simplify your answer (divide numerator and denominator by the common factor of 2) :
4/8 = 1/2
1/2 represents the total amount of cups of yogurt used. Since it took adding 1/8 four times that represents 4 parfaits.
