-3+3x=-2(x+1) First: I will get rid of the bracket:


-3+3x=-2x-2

Now, all the x goes to the left side, all the numbers without x to the right side:


3x+2x=-2+3

we add up"

5x=1

divide by 5:

x= \frac{1}{5}

-3 + 3x = -2(x + 1)

First, regroup your terms. / Your problem should look like: 3x - 3 = -2(x + 1)
Second, expand. / Your problem should look like: 3x - 3 = -2x - 2
Third, add 3 to both sides. / Your problem should look like: 3x = -2x - 2 + 3
Fourth, simplify -2x - 2 + 3 to -2x + 1. / Your problem should look like: 3x = -2x + 1
Fifth, add 2x to both sides. / Your problem should look like: 3x + 2x = 1
Sixth, add 3x + 2x to get 5x. / Your problem should look like: 5x = 1
Seventh, divide both sides by 5. / Your problem should look like: x =  \frac{1}{5}

Answer as fraction: x = \frac{1}{5}
Answer as decimal: x = 0.2

1. Name the triangle. Tell whether each angle is acute, right, or obtuse -------------------------------------------------------
gregori [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the figure of the 3 triangles is not given.

However, I'll give a general tip on how to identify the types of triangles.

1. Right-angled

When one of the three angles of the triangle is 90 degrees, then that triangle is a right-angled triangle

2. Acute triangle

When all the three angles of the triangle are less than 90 degrees, then that triangle is an acute triangle

3. Obtuse triangle

When one of the three angles of the triangle is greater than 90 degrees, then that triangle is an obtuse triangle.

If 18 , x , y , -3 are in A.P then find x + y.
AleksandrR [38]

Answer:

15

Step-by-step explanation:

If this is an arithmetic progression, then there is a common difference.

-3-18 = -21

-21/3 = -7

18 - 7 = x

x = 11

11 - 7 = y

y = 4

4 - 7 = -3

x + y

11 + 4 = 15
