2÷5=0.4
1÷4=0.25
0.4÷0.25=0.016
so she walks at a rate of 0.016 miles per hour
The cost of the 7.5lbs of walnuts would be $2.16
Answer: 75ft
Step-by-step explanation: if you take 3 yards and multiply it by 25 you get 75, or you can do It the long way and add 3, 25 times.
Y=2×2
y=4
4=-3x-1
now add 3x on both sides
3x+4= -1
now substract 4 on both sides
3x = -5
divide 3 on both side
x=-5/3
y= 4
x= -5/3
Answer:
610 feet
Step-by-step explanation:
From the question :
1 scarf = 2.5 yards of yarn
84 scarves = x yards
Cross Multiply
1 scarf × x yards = 84 × 2.5 yards
x yards = 210 yards
Hence, 84 scarves require 210 yards
Converting yards to feet
1 yard = 3 feet
210 yards = x feet
x feet × 1 yard = 210 yards × 3 feet
x feet = 210 yards × 3 feet/1 yards
x feet = 610 feet
Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn
