4b=a then plus 10 to see if the age holds true to 3b=a in ten years. Then since the question is how old is she today? You must either add 6 to young age (of20) or minus 4 from the older (of 30).
So Betty would be 26 today.

The dimensions of the swimming pool and the gym are proportional.
Paladinen [302]
<h3>The dimensions of the gym floor could be 150 feet by 120 feet</h3><h3>The dimensions of the gym floor could be 225 feet by 180 feet</h3>

<em><u>Solution:</u></em>

Given that,

The dimensions of the swimming pool and the gym are proportional

The pool is 75 feet long by 60 feet wide

To find: set of possible dimensions for the gym

To determine the possible dimensions for the gym, you would use the same number to multiply both 75 and 60

<em><u>One set of dimensions are:</u></em>

75 x 2 = 150

60 x 2 = 120

The dimensions of the gym floor could be 150 feet by 120 feet

<em><u>Other set of dimensions:</u></em>

75 x 3 = 225

60 x 3 = 180

The dimensions of the gym floor could be 225 feet by 180 feet

Nostrana [21]

Answer:

I don't know if you want the beginning to so-

Variable - A unknown value represented by a set letter.

4x+6 = 26

(Incase: Subtract 6 from 6, and 6 from 26. 6 cancels out, and 26-6 is 20. Divide both sides by 4. And x=5)

And the answer to the question is: -27 is the smallest, and then the 3 consecutive numbers are -27, -28, and -29.
