Find the value of n. -22*n = -44

Explanation
To find the value of n, we need to solve the equation -22*n = -44. To isolate n, we divide both sides of the equation by -22. This gives us n = -44/-22, which simplifies to n = 2. Therefore, the value of n is 2.

n*12 =-144

Explanation
The equation n*12 = -144 can be solved by dividing both sides of the equation by 12. This will give us the value of n. When we divide -144 by 12, we get -12. Therefore, the value of n that satisfies the equation is -12.

When you divide a positive times a negative the answer will be negative.

A.

True
B.

False

Correct Answer
A. True

Explanation
When you divide a positive number by a negative number, the result will be negative. This is because division is essentially the same as multiplying by the reciprocal, and when you multiply a positive number by a negative number, the result is always negative. Therefore, the answer to the question is true.

42/-6 =

Correct Answer
-7

Explanation
When we divide 42 by -6, we are essentially asking how many times -6 can be subtracted from 42. Since -6 can be subtracted 7 times from 42 (7 x -6 = -42), the answer is -7.

Solve the problems 5/3*-6/2

Correct Answer
-30/6
-5

Explanation
The given expression involves the division and multiplication of fractions. To solve it, we first multiply 5/3 by -6/2, which gives us -30/6. This fraction can be simplified to -5 when we divide both the numerator and denominator by 6. Therefore, the correct answer is -30/6, -5.

-5/2 / -4/6=

Correct Answer
20/12
5/3

Explanation
The given expression is a division of two fractions. To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of -4/6 is -6/4 or -3/2. Therefore, -5/2 divided by -4/6 is equal to -5/2 multiplied by -3/2, which simplifies to 15/4 or 3 3/4. However, none of the given answer options match this result. Therefore, the correct answer is not available.

-6/11 * 5/8 =

Correct Answer
-30/88
-15/44

Explanation
The given expression is a multiplication of two fractions. To multiply fractions, we multiply the numerators and denominators separately. In this case, multiplying -6/11 and 5/8 gives us (-6 * 5) / (11 * 8) = -30/88. Therefore, the correct answer is -30/88.
