-5= -5x-10

Plus 10 from both sides

5=-5x
X = -1

To solve this you would have to use a reverse PEMDAS- it would be easy to start out simplifying the equation so -12 + 7 would be -5. (-5 = -5 (x+2))Next you can try to get rid of the -5 outside the parentheses by adding 5 to both sides, now making the problem 0 = x + 2. So, subtract the two from both sides and you are left with your answer -2= x

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ Carla would weigh 30 pounds.

38/100 x 78 = 29.64

29.64 rounded to the nearest pound is 30.

So, Carla would weigh 30 pounds.

These figures are....
Andre45 [30]

Answer:

C) Similar but not congruent

Step-by-step explanation:

These figures are similar not congruent because:

In order for a triangle to be congruent it has to be the same size and shape.

There is no such thing as congruent but not similar as if it's congruent it is similar.

However, in order for a triangle to be similar it must have the same shape( angles).

So we can see that both triangles are isoceles and the sides of each are in a ratio of 2:1. Meaning that the bigger triangle has sides that are exactly twice as large as the smaller trinage. This also means that the angles are equal. Hence they are similar but not congruent.
