The blank is -8 because -6 +-8=-14+-3=-17.

The answer to this problem would be -8.

__ + (-6) + (-3) = -17

Since the parentheses are only there to differentiate the pluses from the negative signs, we can add together -6 and -3, which equals -9.
Now we have __ + (-9) = -17

We want to get the blank on its own side. To do this, you do the opposite of whatever's on the other side. Since it's a negative nine, you have to add a positive nine to the negative seventeen.

So, we have ____= -17 + 9

-17 + 9 = -8

Hope this helped, and feel free to ask more questions!! (:

Answer:

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

the question states that a person named Ben has two copies of the same poster having different sizes , provided they both are squares !

further , we've been given that the side length of the posters are in the ratio of 3:7 and the perimeter of the smaller posted is 27 cm .

We've been asked to find the perimeter of the bigger poster !

so let's start ~

$let\: the \: length \: of \: the \: smaller \: poster \: be \: 3x \\ \\ let \: the \: length \: of \: the \: bigger \: poster \: be \: 7x \\ \\ now \: , \: \\ \\ perimeter \: of \: square = 4 \times side \\ \\ \implies \: perimeter \: of \: shorter \: square = 4 \times 3x \\ \\ \implies \: 27 = 3x \\ \\ x = \cancel\frac{27}{3} \\ \\ \implies\red{\boxed{ \: x = 9 \: cm}}$

now ,

$side \: length \: of \: bigger \: square = 7x \\ \\ \implies \: 7 \times 9 = 63 \: cm \\ \\ \therefore \: perimeter \: of \: bigger \: square = 4 \times 63 \\ \\ \bold\pink{\implies \: 252 \: cm}$

hope helpful :D

Answer:

-3 b + 16

Step-by-step explanation:

Simplify the following:

-3 (b - 3) + 7

-3 (b - 3) = 9 - 3 b:

9 - 3 b + 7

Grouping like terms, 9 - 3 b + 7 = -3 b + (9 + 7):

-3 b + (9 + 7)

9 + 7 = 16:

Answer: -3 b + 16

What fraction is greater than 1/2 but less than 3/4

aliya0001 [1]

1/2 = 50%

3/4 = 75%

So something in between that could be 2/3 (which equals 66.67% )

A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%)

Hope that helps :)
