First we will do the plus sign for 2.
19 + 2 + 1 + 4 + 2 - 10

Add then subtract.

19 + 2 + 1 + 4 + 2 = 28

28 - 10 = 18.

Now we will do the negative sign for 2.

19 - 2 + 1 + 2 + 4 + 2 - 10

19 + 1 + 2 + 4 + 2 = 28

28 - 2 = 26 - 10 = 16.

Answer is 16 and 18.

What two numbers multiply to negative 8 but add to negative 7
Amiraneli [1.4K]
Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8 
Meaning that the two numbers are -8 and 1.

Seven less than the quotient of a number, x, and twelve is five times the number. Which answer represents this situation??
erica [24]

Answer:

Option b is correct.

Step-by-step explanation:

From the given condition : Seven less than the quotient of a number, x, and twelve is five times the number.

Here, the number is x

The quotient of a number x and twelve is expressed as ,  \frac{x}{12}

Seven less than the quotient of a number, x, and twelve is expressed as,  \frac{x}{12}-7

Five times the number mean, 5x

Therefore, we have an equation in the form of <em>x</em>  from the given condition as:

\frac{x}{12}-7=5x .
