Answer:
Step-by-step explanation:
In 30 minutes she can walk 2 miles. We'll put that as a ratio. 30:2. Now to figure out how much she walks in 45 minutes, we set variable to x and make it stand for how much she walks. We have 30:2 = 45:x We cross multiply to get 30x=90, x=3. Tara can walk 3 miles in 45 minutes.
Answer:
10/3
Step-by-step explanation:
Multiply 2/3 by 5 because 1/5*5=1 hr
2/3*5=10/3
4x+y=16 multiply both sides by -3 and will get
2x+3y=-2
-12x -3y = -48
2x +3y = -2
--------------------------
-10x 0 = -50
-10x = -50
x = -50/(-10) = 5
x = 5
4x+y=16
4*5+y=16
20+y=16
y = 16-20
y = -4
x = 5
y = - 4

The interest rate due is $63.12. Hope that helps you.
Y=12x
Check: 72=12(6)
72=72
y=12x
y=12(10)
y=120
when x is 10 y is 120
