Answer:
The appropriate equation for the above mentioned conditon would be
x+y=7
225x+70y=1110
Step-by-step explanation:
As mentioned in the question the meals contain just two delicacies (i.e. sliders and chicken wings)
Let the number of Sliders be represented by “x”
Let Number of Chicken wings be represented as “y”
As given in the question the total number of sliders and chicken wings equals 7
Hence x + y =7… Equation 1
Further, it is mentioned that each slider carries worth 225 calories of energy and chicken wing carries 70 calories of energy. Total calorie of a meal which contains sliders and wings is 1110 calories.
Thus, Total energy carried by sliders individually = total sliders* energy carried by one slider= 225x
Similarly, Total energy carried by wings individually = total chicken wings* energy carried by one wing= 70y
Thus 225x+70y=1110
Answer:
It would be best if Peter's report card percentage was based on<em> </em><em>the mean</em><em> </em>and if he could drop a percent, he should drop the <em>44%</em><em>.</em>
<em />
Step-by-step explanation:
The median (without dropping a score) of this set would be 75%
( 44%, 64%, 71%, 75%, 84%, 90%, 98% )
The mean (without dropping a score) of this set would be 75.1428571%
526 ÷ 7 = 75.14 ( 7<em>5.1428571 </em>)

Answer:
Let's suppose that one cubic foot of marble is x.
20x = 3400
But because the weight has a range of +-100, then 20x is between 3300 and 3500. Write it like this:
3300<20x<3500
Divide by 20:
165<x<175
The meaning of this is that one cubic foot of marble weight between 165 and 175 pounds
