Don’t trip just use the distributive property. -5(3x-2)= -50 which would end up being -15x -7 = -50; then add 7 to both -7 which then they will cancel out and add 7 to -50 which equal -43 so x = -43

Answer:

x = 4

Step-by-step explanation:

Okay so for this equation we have this:

-5(3x - 2)= - 50

because the 3x and -2 are in a parentheses that shows we have to multiply -5 we do like this:

(3x(-5) - 2(-5)) = -50

-15x + 10 = -50

Since we want to get rid of the 10 we are going to subtract 10 from both sides:

-15x + 10 = -50

       - 10    -10

Since we are actually going to add -10 to -50 its going to look more like this:

-15x = -60

Now we are going to divide -15 from -15x and -60 in order to segregate -15 from x:

-15x/-15 = -60/-15

x = 4

Now we double check our work by placing 4 where x once was:

-5(3(4) - 2)= - 50

-5(12 - 2) = -50

-60 + 10 = -50

-50 = -50

Hope this helps

Phantasy [73]

Perimeter of triangle = 3(side)

P = 3(s)

12 = 3s

12/3 = s

4 = s

I think there is a typo in your post.

The question should be: WHICH ONE OF THE FOLLOWING IS A POSSIBLE SIDE OF THE TRIANGLE?

In that case, 4 cm is the answer. However, 4 cm is not listed among the choices. So, choice d is the answer.

The Falcone family is planning to drive from Syracuse, New York to Buffalo, New York. On a map with a scale of
Ad libitum [116K]

Answer:

The Falcones have to travel at 25 m/h to make the trip in 2 hours.

Step-by-step explanation:

In order to find the answer you have to use the formula to calculate speed:

speed=distance/time

distance=50 miles. The stament indicates that the distance between Syracuse and Buffalo is 1 inch and that the map has a scale of inch = 50 miles.

time=2 hours

Now, you can replace the values on the formula:

speed=50 miles/2 hours

speed=25 m/h

According to this, the answer is that the Falcones have to travel at 25 m/h to make the trip in 2 hours.
