Answer:
1 x 10 = 10
2 x 10 = 20
3 x 10 = 30
4 x 10 = 40
5 x 10 = 50
6 x 10 = 60
7 x 10 = 70
8 x 10 = 80
9 x 10 = 90
10 x 10 = 100
11 x 10 = 110
12 x 10 = 120
Step-by-step explanation:
So we go up in 10's. It simply goes like this, 10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160,170,180,190,200... etc.
The expression would be 5x + 2y = 20
We let x be no of hardcover books, and 5x the cost of those books
Same for paperbacks.
then we add them up to 20.
Done!
4, -3
The quadratic formula is .
When using the formula for both the negative and positive value of the sqrt, you will get:
x = 4, -3

32 jelly beans were in the bag
We know 75% is 3/4 and that she ate 24, so divide 24 by 3 then multiply it by 4:
24/3= 8
8 x 4 = 32
