Ahealth club chargers non-members $5 per day to swim and $9 per day for an exercise class. members pay a yearly fee of $300 plus $4 per day to attend an exercise class and no swim fee. if robert swims and takes an exercise class every time he goes to the gym, which equation shows the number of days, d, he must use the gym to make the membership worthwhile?
5d+9d
= 4d
300
5d+9d
=300
4d
5d+9d=300-4d
5d+9d=300+4d

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !

i think da answer is

d.square root of 3
