The answer is 8/9n - 1 1/3.

Explanation:

When multiplying a fraction by a whole number, you multiply the numerator by the whole number. In this case, doing so would result in 8/9n. Because the same principle would apply for the other part of the equation, we can do 4/9 x -3 to get -12/9. -12/9 is improper, so we could standardize it to get the equation’s expression in simplified form. -12/9 simplified is -1 1/3. The answer would be 8/9n - 1 1/3 because when there is a negative factor, the expression becomes a subtraction problem. Thus, your equation is 8/9n - 1 1/3.

4) (p-4)(p+2)

5)(7x-10)(x+1)

6)(7n-1)(n-9)

Step-by-step explanation:

1) Factors of -5 that add up to 4

2) Factors of --12 that add up to -1

3) Factors of 4 that add up to -5

4) Factors of -5 that add up to 4

5) 7 $x^{2}$ -3x-10

7 $x^{2}$ +7x-10x-10

7x(x+1)-10(x+1)

(7x-10)(x+1)

6)7 $n^{2}$ -64n+9

7 $n^{2}$ -63n-n+9

7n(n-9)-(n-9)

(7n-1)(n-9)

The probability of a spinner landing on a 4 is 5/8. What is the probability that the spinner will land on a number other than 4?

Alja [10]

The probability that it doesn't land on 4 would be 3/8. This is because theres a 5/8 chance it lands on 4 so just do the opposite which would be 3/8.
