Answer:
40?
Step-by-step explanation:
I did 30/6=5 (assuming he took the same amount per week) then added 10 to get 40
Andy took 40 quizzes in 8 weeks
6 goes into 30 5 times. Next multiply 5 by 8 and you will get your answer of 40.
x = -6
Distribute the 2 into the brackets:
2x + 10 = -2
leave the 2x alone on one side:
2x = -2 -10
2x = -12
divide both sides by 2:
just divide 18 by 1920 duh
