1:2:3...total is 6
1/6 of 5 1/4 = 1/6 * 21/4 = 21/24 = 7/8
2/6 of 5 1/4 = 2/6 * 21/4 = 42/24 = 1 3/4
3/6 of 5 1/4 = 3/6 * 21/4 = 63/24 = 2 5/8
7/8, 1 3/4, 2 5/8...total = 5 1/4 inches
Step-by-step explanation:
5(2x+4)=15
10x+20=15
10x=15-20
<u>1</u><u>0</u><u>x</u>= <u>-</u><u>5</u>
10. 10
x=-1/2
- Anything times(x) 1 is ONE
- Anything times 2 always has an even number at the end
On and On
Here's a picture I got from online.
Let the number of bike be x and the number of skates be y, then
21x + 20y ≥ 362 . . . (1)
2y = x . . . (2)
Putting (2) into (1), then
21(2y) + 20y ≥ 362
42y + 20y ≥ 362
62y ≥ 362
y ≥ 5.84
The least number of pairs of skates they need to rent each day to make their minimum is 6.
