Simplify the rational expression:<br> 5y+5/2 ÷ 25y-20/40y²-32y
NNADVOKAT [17]

Step-by-step explanation:

Your problem → 5y+5/2 / 25y-20/40y^2-32y

5y+5/2÷25y-20/40y^2-32y

=5⋅y+5/2÷25×y-20/40×y^2-32×y

=5y+5/2÷25×y-20/40×y^2-32y

=5y+5/2×1/25×y-20/40×y^2-32y

=5y+y/10-20/40×y^2-32y

=5y+y/10-y^2/2-32y

=5y×10+y-y^2×5-32y×10 ÷ 10

=50y+y-5y2-320y ÷ 10

= -269y-5y^2 / 10

The Children’s Hospital sponsors a 10K race to raise money. It receives $75 per race entry and $10,000 in donations, but it must
svetlana [45]

THE ANSWER:


There would need to be at least 1,800 entries in order for them to meet their goal.


Step-by-step explanation:


To find this, we must write an equation that helps solve it. We know that for every entry (x), we gain 75 and lose 25. We can express this as the following.


75x - 25x


Then we can add the number of donations.


75x - 25x + 10,000


Then we can set it as greater than or equal to the goal number.


75x - 25x + 10,000 ≥ 100,000


Now we solve this using the order of operations.


75x - 25x + 10,000 ≥ 100,000 ----> Combine like terms


50x + 10,000 ≥ 100,000 ------> Subtract 10,000


50x ≥ 90,000 -----> Divide by 50


~~~~~~~~~x ≥ 1,800~~~~~
