Answer:
The first rate is 6 miles per hour
The final rate is 6+2 or 8 miles per hour
Step-by-step explanation:
We know d = rt where distance is equal to rate times time
First part
d1 = r * 1/3
Second part
d2 = (r+2)(3/4)
We know the total distance is 8 miles and is
d1+d2 = 8
r * 1/3 + (r+2)(3/4) = 8
Multiply each side by 12 to get rid of the fractions
12( r * 1/3 + (r+2)(3/4)) = 8*12
4r +(r+2) 9 = 96
Distribute
4r+ 9r +18 = 96
Combine like terms
13r +18 = 96
Subtract 18 from each side
13r+18-18 = 96-18
13r = 78
Divide each side by 13
13r/13 = 78/13
r=6
The first rate is 6 miles per hour
The final rate is 6+2 or 8 miles per hour
Answer:
x=2
Step-by-step explanation:
8x- 1/3 y = 16
when y = 0
8x = 16
x = 2
x-intercept (2,0)
The shirts can be called A, B, C, D, E, F.
the pants can be called 1, 2, 3, 4.
if you combine these together you get
A1, A2, A3, A4, B1, B2, B3, B4, C1, C2, C3, C4, D1, D2, D3, D4, E1, E2, E3, E4, F1, F2, F3, F4 OR 24
You get 24 outfits.
The difference is that each number that comes after gets multiplied by 4
