Using this, we can see that anytime 3 negatives are multiplied, the answer will always be negative.

Solve the equation a + b - c = 180 for a. *

spin [16.1K]

Answer:

a = 180 - b + c

Step-by-step explanation:

a + b - c = 180

Move b by subtracting b from both sides.

a - c = 180 - b

Move c by adding c to both sides.

a = 180 - b + c

Therefore a equals 180 - b + c.

Multiply. (−23)(54) Enter your answer as a fraction, in simplified form, in the box.

Sati [7]

Answer: $-\frac{1242}{1}$

Step-by-step explanation:

By definition, negative numbers, positive numbers and zero are Integers.

It is important to remember the multiplication of signs:

$(-)(-)=+\\(+)(+)=+\\(-)(+)=-$

You can observe that you must multiply two integers, one of them is negative and the other one is positive. The product will be an integer. Then:

$(-23)(54)=-1242$

Since any Integer can be written as a fraction, you can rewrite the product by writing $-1242$ as the numerator and $1$ as the denominator.

Then, this is:

$=-\frac{1242}{1}$
