Answer:
Step-by-step explanation:
-3(3x - 4) = - 9x - 12 ...distribute thru the parenthesis

-9x + 9x = -12 - 12
0 = -24 (nope)

Answer:
The answer is 5 students taking English and Math but not History
Step-by-step explanation:
The total students are 28 which are divided into 5 possible groups with no students taking either English only or History only:
- Taking Math only
- Taking English and Math but not History
- Taking Math and History but not English
- Taking English and History but not Math
- Taking triple subjects
The number of students in group 3 is 6. Hence, the total number in group 1, 2, 4 and 5 is: 28 - 6 = 22
Also, the number of students in group 4 is five times the number in group 5, therefore: group 2 + group 5 = 6 times group 5
Additionally, the number of students in group 1 equals that in group 2.
Hence, the equation is: 6 x group 5 + 2 x group 2 = 22 => group 2 = 11 - 3 x group 5 => group 2 = 5 because group 5 is an even number and non-zero, it must be 2.
