-30x - 20: We can see that both numbers have a factor of -10, because 30 and 20 are multiples of 10 and -30x and -20 are both negative. So the factored form is -10(3x + 2).
12x - 28: The greatest common divisor of the two numbers is 4, so the factored form is 4(3x - 7).
-10x - 5: Like the first problem, the biggest factor is -5, so the factored form is -5(2x + 1).
Answer:22
Step-by-step explanation:22
You must first attach the problems with your question.
So x=7 and y=10 because 35+70 equals 105 what i did is just plugged in numbers.
Answer:
90%
Step-by-step explanation:
First, find the total number of tickets sold.
810 discount + 90 full-price = 900 tickets
Now you need to find what percent 810 is of 900.
% of 900 = 810
810/900 = 0.9
Convert this to a percentage.
0.9 × 100% = 90%
90% of tickets were sold at a discount.
