Answer:
y= -3/2x +30
Step-by-step explanation:
There are 550 students at the green country middle school and 220 of them ride the bus to school. What percent of the students ride the bus?
The fraction 
represents the number of students that ride the bus to school out of all the students.
To find what percent of students ride the bus to school, we can turn the fraction 
into a percent.
We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 220 and 500 using 20.
220 ÷ 20 = 11
500 ÷ 20 = 25
11 ÷ 25 = 0.44
0.44 × 100 = 44%
Therefore, 44% of the students ride the bus to green country middle school.
Answer:
y=6x-6
Step-by-step explanation:
i think not sure tho
This is equal to (x -5)(x - 5), or (x - 5)².
<span>Therefore, using the formula given above, the side's length is equal to (x - 5). </span>
<span>Muliply that by four to obtain the perimeter. </span>
<span>4(x - 5) = 4x -20. </span>
<span>For the second problem, disregard the brackets since there are no other operations besides subtraction and addition. </span>
<span>So it would become 3x^4 -x + 2 + 9x^5 - x² + x. </span>
<span>Now simplify everything and rewrite it in decreasing terms of power, </span>
<span>9x^5 + 3x^4 - x² + 2. </span>
