Answer:
328
Step-by-step explanation:
If z is 0, then x has 9 choices. Therefore, z and x can be chosen in (1 × 9) + (4 × 8) = 41 ways. For each of these ways, y can be chosen in 8 ways. Hence, the desired number is 41 × 8 = 328 numbers 3-digit even numbers exist with no repetitions.
First, calculate the ones that is in the bracket, 4/5×1/3 = 4/15 (make the denominator the same), second finish the question, 7 - 4/15.
Answer, 6&11/15. (six and eleven over fifteen.
Answer:
Only Annabelle is correct.
Step-by-step explanation:
So we have the expression:
When multiplying exponents with the same base, we can use the following property:
Essentially, we add the exponents together.
So, first group them:
Use the property:
And so our answer is:
So, Annabelle's answer is correct.
Navene incorrectly used the property. The property adds the exponents, it doesn't multiply them.
So, only Annabelle is correct.
And that's our answer :)
P.S. Congratulations on finishing!
Divide 1075 by 105 to get 10.2 that way you dont get it wrong i hope that helped
Let's say the number is represented by x.
Five times the number is 5x.
5x - 58 = -23 (Add 58 to both sides)
5x = 35 (divide both sides by 5)
x = 7
The number is 7.
