Translate into an algebraic expressions: x is increased by 50% and decreased by 30% . What is the result?

1.05x

Step-by-step explanation:

From the question, we are informed to translate into an algebraic expressions: x is increased by 50% and decreased by 30%. This will be calculated thus:

Firstly, we'll increase x by 50%.

= x + (50% of x)

= x + (0.5 × x)

= x + 0.5x

= 1.5x

Then, we'll decrease 1.5x by 30%. This will be:

= 1.5x - (30% × 1.5x)

= 1.5x - (0.3 × 1.5x)

= 1.5x - 0.45x

= 1.05x

The answer is 1.05x.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
