Let us assign variables.
Let x = egg mcmuffins
Let y = hash brown
Randy had:
2x + y = 750
Jack had
x + y = 450
Using systems of linear equation, we can get the value for x and y by elimination. Subtract the equations.
2x + y = 750
x + y = 450
--------------
x = 300
Get y
x + y = 450
300 + y = 450
y = 150.
So there are 300 calories for McMuffins and 150 calories for hash brown.

Step-by-step explanation:
total number of students in 1 class: 12 + 6 = 18 students
percentage of student wearing glasses are:

Done :))
Average thickness of book = Total thickness/mo. of books
= 28 cm/ 10
= 2.8 cm
Thus, on average, each book has 2.8 cm thickness.
If the y intercept isn't -5 go to ur coordinate that is given and find where the y intercept is and plug in the y intercept to y=mx+b
