larisa [96]

Answer: Total cost is $1.75

Explanation:

Since we have given that

Number of postcards bought by Doug's family= 7

Cost of each postcard including tax = $0.25

Total cost is given by

$7\times 0.25=\$1.75$

Now, we want to show this in number line :

On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.

Each step is of length 0.25 and there are 7 jumps to reach required answer.

So, after 7 jumps we reach at 1.75 which is the required answer.

Hence total cost is $1.75

In your notebook, set up the following subtraction in a vertical format and select the correct answer.

prohojiy [21]

Answer:

$4p^{2} +6p-8$

Step-by-step explanation:

Remember these rules for addition, substraction, multiplication or division:

Addition

+ + = +

- - = -

Big + number - = +

Big -number + = -

Substraction

change the sign!

And follow the rules for addition

Multiplication or division

+ + = +

- - = +

+ - = -

Now for the exercise

$2p^{2} + 3p - 4$

- ( $- 2p^{2} -3p +4$ )

Change the signal

$2p^{2} + 3p - 4$

( $+2p^{2}+3p-4$ )

$4p^{2} + 6p -8$
