They are both running at the same speed.Let me explain mathematicallyLets set up a unit rate.We want to know how many miles they all ran in 1 minute. Izzy did 2 1/4 divided by 15 which gives point 15 miles.Julia did 3 3/4 divided by 25 witch gives Point 15After that you can see who ran faster.you can convert it per minute instead of hours. you will get the same answer
11% the answer is that because 32 +18= 50 then 26+13=39 add 50 and 39 it = 89 then left is 11 so 11%
Answer:
x + y = 15
0.5x + 0.65y = 9
Step-by-step explanation:
x = number of oranges
y = number of apples
total of apples and oranges is 15 so x + y = 15
total cost of apples and oranges is $9 so 0.5x + 0.65y = 9
Calculation
y = 15 - x
0.5x + 0.65(15-x) = 9
0.5x - 0.65x + 9.75 = 9
-0.15x = - 0.75
x = 5
y = 15 - x = 15 - 5 = 10
Independent variable = $20
dependent variable = $0.05 cents per min
y = total month cost
x = month minutes used
y = 20 + 0.05x
