Answer:

Step-by-step explanation:

You need to simply add all the given numbers together and enter the missing number that'll make the total 0. So:

-75 + (-25) = -100

-100 + 10 = -90

-90 + 90 = 0

Thus, adding a 90 in the empty box will make it 0.

Answer:

Step-by-step explanation:

This is the answer because:

1) -75 + (-25) = -100

2) -100 + 10 = -90

3) -90 + 90 = 0

Therefore, the answer is 90 because whenever a negative number is added with the same poitive number, it beomes a 0.

Hope this helps! :D

Is the quotient of 3.6 divided by 9 greater or less than 1?

Kisachek [45]

Answer:

Step-by-step explanation:

The given quotient is

$\frac{3.6}{9}$

In this case, before solving the quotient, we can ensure that its result is less than 1, because the numerator is less than the denominator, this is called a "proper fraction", and those fraction always ends in a number less than 1.

$\frac{3.6}{9}=0.4$

Therefore, the answer is "less than 1".

Rewrite the expression 2(x + 5) using the Distributive Property.

ehidna [41]

Answer:

2x + 10

Step-by-step explanation:

To expand (using the distributive property) multiply the number outside the bracket i.e. in this case '2', with the values inside the brackets.

So multiply '2' and 'x' and '2' and 5' and add or subtract on basis of whether the second value is positive or negative.

2(x + 5)

= (2*x)+(2*5)

=2x+10

extention note: be careful when the symbol within the equation within the brackets is a subtraction because it implies that the second value would instead be a negative number and should be treated as such.

an example

2(x-5)

= (2*x)+(2*-5)

=2x -10

Anyhow, I hope this helped!
