Find the sum.
negative 4 plus 16

12

Step-by-step explanation:

To add a positive number and a negative number do this:

1. Keep the positive number as it is.

2. Make the negative number positive by dropping the negative sign.

3. Using the two positive numbers, subtract the smaller number from the larger number.

4. The sign of the answer is the same sign as the larger original number.

Now that you see the rule above, I'll do your problem one step at a time.

1. Keep the positive number as it is. 16 remains as 16.

2. -4 becomes 4.

3. Subtract the smaller number form the large number: 16 - 4 = 12.

4. The original numbers were -4 and 16. 16 is greater than 4, and 16 is positive, so our answer is positive.

-4 + 16 = 12

18a

step-by-step explanation:

simply because it is. it's the highest common factor

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
