A swimming pool charges $6 for adults and $4 for children. On a particular day, they made $1,326 in admissions. If a total of 28
muminat
X= # of adults
y= # of children

1326= 6x + 4y
289= x + y

We are going to do substitution.

x = 289-y
1326= 6(289-y) + 4y
1326= 1734 -6y + 4y
1326= 1734 + -2y
-408= -2y
204 = y

Since we now have a value for y, we should plug that back into the equation we got the x value from to find the actual numerical value of x.

289= x + y
289= x + 204
85= x

In conclusion, 85 adults and 204 adults went to the swimming pool.

Divide 35b^5 +20ab^3 +20a^2b^2 by 5b^2
Nookie1986 [14]
Basically, you just divide each term in the equation by b^2.
So 35b^5 / b^2 = 35b^3, 30ab^3 / b^2 = 30ab, and 20a^2b^2 / b^2 = 20a^2.
So your final answer is 35b^3 + 30ab + 20a^2.

120 is increased by b% then increased by 25%. What is the result?
Allushta [10]

Answer:

150 + 1.5d

Step-by-step explanation:

increase 120 by d%

d% = d/100

So, increasing 120 by d % means

120 + (d/100 * 120)

= 120 + 1.2d

Then increase this by 25%

= (120 + 1.2d) + 25/100(120 + 1.2d)

= 120 + 1.2d + (120+1.2d)/4

= 120 + 1.2d + 30 + 0.3d

= 120 + 30 + 1.2d + 0.3d

= 150 + 1.5d
