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.
4.5 x 10 to the power of 4
Answer:
x = 10
<u></u>
Step-by-step explanation:
2x - 4 = 16 try to get x on the left side, and the integers on the right
You then get:
2x = 20
Now, divide by 2 on both sides
2x/2 = 20/2
<u>x = 10</u>
When billy turns 18 he will have $3,099.6 in his account because .021 percent x $8,200= $172.20 per year x 18 years = $3,099.60
That square in a means that it’s 90 degrees and b is 70. Well it says that ab = bc. And ab together is 90+70 which is 160. A straight line is 180 in total so to figure that other side of b out do 180-70 which is 110. So now you have 110, and to match ab you need 50 more degrees for bc. Therefore c is 50 degrees
