You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x
2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
Answer:
∠ A = 50°
Step-by-step explanation:
The angle adjacent to 145° inside the triangle is
180° - 145° = 35°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
85° is an exterior angle of the triangle , then
∠ A + 35° = 85 ( subtract 35° from both sides )
∠ A = 50°
For this case we have to:
x: Let the variable representing the unknown number
We algebraically rewrite the given expression:
Twice a number plus 10, is represented as:
Three times that number less 4. is represented as:

Thus, the complete expression is:

Subtracting 3x from both sides of the inequality:

Subtracting 10 from both sides of the inequality:

Equal signs are added and the same sign is placed:

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

The solution is given by all values of "x" less than 14.
Answer:

The side of the small triangle that will correspond to the side of HI is side IK.
<h3>How to find corresponding side of similar triangles?</h3>
Similar triangles are triangles that have the same shape but different size.
In similar triangles, corresponding sides are always in the same ratio.
The corresponding angles are equal.
Therefore, the side of the small triangle that will correspond to the side of HI is side IK.
