Mr.Utley’s class has a greater band to chorus student ratio
Step-by-step explanation:
Step 1 :
Number of students in band in Mrs.Washington’s class = 2 for every 3 students in chorus.
Number of students in band in Mr.Utley’s class class = 5 for every 7 students in chorus.
Hence
the ratio of band students to chorus students in Mrs.Washington’s class = 2 : 3
the ratio of band students to chorus students in Mr.Utley’s class = 5 : 7
We need to determine which is the greater ratio
Step 2 :
Ratio 1 = 2: 3
Ratio 2 = 5:7
Converting to common denominator we have
Ratio 1 = 14 : 21 and ratio 2 = 15:21
So the ratio 15:21 = 5:7 of Mr.Utley’s class is greater
Step 3 :
Answer :
Mr.Utley’s class has a greater band to chorus student ratio
I don’t know yet but calculated is 30
. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
B is right option
4x + 2y = 32
5x + 2y = 36 subtracting
-x=-4
x=4
4(4)+2y=32
16+2y=32
2y=16
y=8
hope this helps
Hello,
Simplifying is simply putting the expression into it's lowest terms. It's like simplifying a fraction. See how it can get put into it's lowest terms, then you complete it. I can't help you any further without a real equation.
