Marlene drove 540 miles to visit a friend. She drove 3 hours and stopped for gas. She then drove 4 hours and stopped for lunch. How many more hours did she drive if her average speed for the trip was 60 miles per hour?
With an average speed of 60 miles per hour, the time she needs to finish 540 miles is: 540/60 = 9 hours. 9 hours - (3 + 4) hours = 2 hours. She drove 2 more hours.

Carlos has \$3.35 in dimes and quarters. If he has a total of 23 coins, how many dimes does he have? a 9 b 11 c 16 d 18
Updated 4/9/2014 8:13:29 PM
Let x be the number of dimes he has and y be the number of quarters,
we were given:
x + y = 23
10x + 25y = 335
Solve the equation we get x = 16
Carlos has 16 dimes.

Solve each system of equations. If possible, write your answer as an ordered pair. y = -3x + 2 y = 4x - 5
Weegy: 4x + 12 = -3x - 6 + 4x, 4x + 12 = x - 6, 12 + 6 = x - 4x, 18 = -3x or -3x = 18, x = -6 (More)

y = -3x + 2
y = 4x - 5
replace y in the first equation we get:
4x - 5 = -3x + 2
4x + 3x = 2 + 5
7x = 7
x = 1
y = 4(1) - 5 = -1
The solution for the system of equations y = -3x + 2 y = 4x - 5 is (1, -1)

Solve each system of equations. If possible, write your answer as an ordered pair. y = 5x - 3 y = 2x + 6
Updated 4/9/2014 8:04:27 PM
y = 5x - 3
y = 2x + 6
replace y in the first equation we get:
2x + 6 = 5x - 3
2x - 5x = -3 - 6
-3x = -9
x = 3
y = 5(3) - 3 = 15 - 3 = 12
The solution for the system of equations y = 5x - 3 y = 2x + 6 is (3, 12)

Solve each system of equations. If possible, write your answer as an ordered pair. x + y = 8 x + 3y = 14
Weegy: 1 x - 3 y = - 6 ? y = x 3 + 2 (More)

x + y = 8
x + 3y = 14
the first equation - the second equation: 2y = 6
solve the equation: y = 3
x + 3 = 8, x = 5
The solution for the system of equations x + y = 8, x + 3y = 14 is (5, 3)

Solve each system of equations. If possible, write your answer as an ordered pair. y = -2x + 6 y = 3x - 9
Weegy: x = 2.5 (More)

y = -2x + 6
y = 3x - 9
Replace y in the first equation:
3x - 9 = -2x + 6
5x = 15,
x = 3
y = -2(3) + 6 = 0
The solution for the system of equations y = -2x + 6 y = 3x - 9 is (3, 0)
