Answer:

-7x-1

6-(9x+7)+2x

-(9x+7): -9x-7

= 6-9x-7+2x

6-9x-7+2x=-7x-1

Answer:

-7x - 1

Step-by-step explanation:

Well to start off we have to multiply because of the - symbol at the start of the parenthesis.

So - * 9x is -9x and - * 7 is -7 so our equation looks like this now 6-9x-7+2x=.

Now we have to combine like terms so 6 + -7 is -1 and -9x + 2x is -7x.

So now our equation looks like this -7x-1=.

So that is simplifued all the way.

Makovka662 [10]

Answer:

Option D is correct.

75 miles is the total distance in miles to Kirk's grandmother's house

Step-by-step explanation:

Let x represents the total distance in miles to Kirk's grandmother's house.

As per the statement:

Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house

⇒ Distance Kirk's family drove = 36 miles.

then;

36 = 48% of x

36 = \frac{48}{100}x

Multiply both sides by 100 we get;

3600 = 48x

Divide both sides by 48 we have;

75 miles = x

Therefore, the total distance in miles to Kirk's grandmother's house is 75 miles
