To solve this first, you need to know that we have to note that (+) × (-) = (-). Therefore, 1.25+(-0.75) will be thesame as writing 1.25 - 0.75. This will then be:
= 1.25 - 0.75
= 0.50

Answer:
y = -4/5x + 2/5
Step-by-step explanation:
Let x = the number of robotics club students
Then x + 11 = number of science club students
The total number of students = 75 = x + x + 11
so 2x + 11 = 75
2x = 75 - 11
2x = 66
x = 33
and
x + 11 = 33 + 11 = 44 = number of science club students
