This is how I do it. If it is a negative minus a negative, I combine the two - signs to make it an addition problem. Ex. -3 - -4 makes -3+4. The answer would be one.
If it is a negative plus a negative, keep the sign on the greater number and take away the sign the smaller number. Ex. -7 + (-9). Keep the sign on the 9. -7 - 9. The answer would be -16.
you have to simplify it
then isolate the variable
then you will get x=6
Answer:
24.2 marks
Step-by-step explanation:
25 + 36 + 20 + 15 + 24 + 30 + 38 + 32 + 22 = 242
since there are 10 students we divide 242 by 10 and get 24.2
0.3
according to the graph the intercept is on point line of 0.003 so we take that run it through some multiples we get 0.3
1 x 5 = 5 + 3 = 8
