The answer is going to be 29 because

I calculate the sum from starting with (-7+10))

So once I did that it’s 2-3(3-4(3)

Now you multiply the digits

2-3(3-12)

Now you subtract for 3-12


Which is -9 now you have 2-3(-9)

A negative times a negative is a positive

So 2+27=29

That’s how I got my answer. If this helps please give me brainiest and have a wonderful day

3(x + 4) = 27 what is x
Alla [95]

Answer:

x = 5

Step-by-step explanation:

This is a simple equation if you look at it right and don't get scared by the "x."

All we need to do is figure out what times 3 = 27. We can do this easily by diving 27 by 3.

27 ÷ 3 = 9

Since our "equation" is 3(x + 4) = 27 we know whatever is in the parenthesis () has to equal to 9. We already get 4 so:

5 + 4 = 9.

3 times 9 = 27.

5 is your answer.

<u>Hope this helps and have a nice day!</u>

PS if you could mark brainliest that'd be great! I'm very close the "expert" rank. Haha, sorry I usually don't ask.

WHAT IS THE SLOPE OF THE LINE PASSING THROUGH THE POINTS (-2, -7) AND (3, 5)?????? PLZ ANSWER QUICKLY!!​
jarptica [38.1K]

Answer:

The slope of the line with points A(-2, -7) and B(3,5)  is  m =  (12/5).

Step-by-step explanation:

The two pints are given as A(-2, -7) and B(3,5)

Slope of a line with points (a,b) and (c,d) is given as

m =( \frac{d -b}{c-a} )

So, here the slope of line AB is

m =( \frac{5 - (-7)}{3 - (-2)} )  = \frac{5+ 7}{3 +2}   = \frac{12}{5}

or, m = 12/5

Hence, the slope of the line with points A(-2, -7) and B(3,5)  is (12/5).
