Answer:
B. W = (P - 2L) / 2
Step-by-step explanation:
(I'm gonna use capitals so it's easier to identify length and width variables)
P = 2L + 2W
Isolate w:
P - 2L = 2W
(P - 2L) / 2 = W
Divide two corresponding sides:
GN is corresponding to AL
15 /20 = 3/4
The scale is 3/4
Answer: 22 miles
Step-by-step explanation:
1/4 times 4 = 1 gallon
if Rob can travel 5 and 1/2 miles on 1/4, then to find how far he can travel on 1 gallon we multiply 51/2 by 4
5 1/2 x 4 = 22
28. This equation satisfies the condition
-x - 10 = -17
29. You can use this equation
x/5 + 5 = 0
30. The error is dividing the equation first by 3. The solution should have been
3x + 2 = 15
3x = 15 - 2
3x = 12
3x/3 = 12/3
x = 4
31.
x/4 - 6 = 2
x/4 = 2 + 6
x/4 = 8
x = 8(4)
x = 32
