Answer:
(x,y) = (3x,3y)
Step-by-step explanation:
0.250*140,000,000=35,000,000
40,000,000/35,000,000= 1.14
So about 1 time
Answer:
24 minutes
Step-by-step explanation:
Working at the same speed, the ratio of time to length is the same:
time/length = t/12 = 3/(1.5)
t = 12(3/1.5) = 12(2) = 24
It will take Mark 24 minutes to make a 12-inch bracelet.
The answer is 12 because you have to subtract
32-20
As we are given with
