Step-by-step explanation:
160 miles = 20 gallons
400 miles = x gallons
160 × x = 20 × 400
x = 8, 000/160
x = 50 gallons
4pm because it takes them 3 hours to get set and sunset is at 7pm so 7-3=4pm boom!
Answer:
x= -674
Step-by-step explanation:
Solve for x and check: x + 5 = 3
Solution
Solve for x and check: - 3x = 12
Dividing each side by -3, we obtain
Another way of solving the equation
3x - 4 = 7x + 8
would be to first subtract 3x from both sides obtaining
-4 = 4x + 8,
then subtract 8 from both sides and get
-12 = 4x.
Now divide both sides by 4 obtaining
- 3 = x or x = - 3
Solve for c: 3(x + c) - 4y = 2x - 5c
First remove parentheses.
Remember, abx is the same as 1abx.
We divide by the coefficient of x, which in this case is ab.
Y4 - y3 + 2y2 + y - 1 over (y + 1) • (y2 - y + 1)
