Ben is 20 years older than daniel. ben and daniel first met two years ago. three years ago, ben was 3 times as old as daniel.
how old is daniel now?

Daniel=13.

Step-by-step explanation:

We can use the given information to write down two equations that describe the ages of Ben and Daniel.

Let Ben's current age be b and Daniel's current age be d.

The information in the first sentence can be expressed in the following equation:

Three years ago, Ben was b−3 years old, and Daniel was d−3 years old.

The information in the third sentence can be expressed in the following equation:

Now we have two independent equations, and we can solve for our two unknowns.

Because we are looking for d, it might be easiest to use our first equation for b and substitute it into our second equation.

Our first equation is: b=d+20. Substituting this into our second equation, we get the equation:

which combines the information about d from both of our original equations.

Simplifying both sides of this equation, we get: d+17=3d−9.

Solving for dd, we get: 2d=26.

d=13.

step-by-step explanation:

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
