I assume you mean "if you switch the numbers." If so, I am now 73 and my daughter is 37. Last year, she was 36, while I was 72, which is twice as old as 36.

Solve the equation 1/3 (x + 1) +2x =2

            Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

Let's solve your equation step-by-step.

\frac{1}{3} (x+1)+2x=2

Step 1: Simplify both sides of the equation.

\frac{1}{3} (x+1)+2x=2

(\frac{1}{3}) (x) + (\frac{1}{3} ) (1) + 2x = 2 (Distribute)

\frac{1}{3} x  + \frac{1}{3} + 2x = 2

( \frac{1}{3} x + 2x ) + (\frac{1}{3}) = 2 (Combine Like Terms)

\frac {7}{3} x + \frac{1}{3} = 2\\\frac{7}{3} x + \frac{1}{3} = 2

Step 2: Subtract 1/3 from both sides.

\frac{7}{3} x + \frac{1}{3} - \frac{1}{3} = 2 - \frac{1}{3} \\\\\frac{7}{3} x = \frac{5}{3}

Step 3: Multiply both sides by 3/7.

( \frac{3}{7} ) * (\frac{7}{3}x) = ( \frac{3}{7}) * \frac{5}{3}   \\\\x = \frac{5}{7}

So the answer is : x = \frac{5}{7}

A swim coach wants to test whether practicing with swim paddles improves swimmers' breaststroke times in the 100-
arsen [322]

Answer: experimental

Step-by-step explanation:

In a research design such as the one described in the scenario above, participants are separated into two distinct groups. The hypothesis (if swimming with paddles is faster than without paddles) being tested is applied on one of the two groups while the other group remains as before. Hence, the group which receives the treatment which is to be tested (those who swim with paddles) are called the experimental group. The other group of participants who continue to swim without paddles are the control group.

Hence, the other group of three member who were asked to swim with paddles for two weeks are the experimental group because they are the ones who received the actual treatment in the experiment.
