Answer:
x = length of sitcoms = 21 minutes
y = length of dramas = 42 minutes
Step-by-step explanation:
Let
x = length of sitcoms
y = length of dramas
6x + 6y = 372 (1)
2x + 6y = 288 (2)
Subtract (2) from (1) to eliminate y
6x - 2x = 372 - 288
4x = 84
x = 84/4
x = 21
Substitute x = 21 into (1)
6x + 6y = 372
6(21) + 6y = 372
126 + 6y = 372
6y = 372 - 126
6y = 246
y = 246/6
y = 41
x = length of sitcoms = 21 minutes
y = length of dramas = 42 minutes
Answer:
AOB = 73
BOC = 107
Step-by-step explanation:
So make an equation.
9x + 27 = 180
9x = 153
x = 17
AOB = 73
BOC = 107

Answer:
See explanation
Step-by-step explanation:
There are 4 red tulips and 9 white tulips in a vase.
1. You can group 1 red tulip and 9 white tulips. This group of tulips consists of
1 red tulip + 9 white tulips = 10 tulips.
If there were 4 red tulips, then
4 - 1 = 3 red tulips left.
In total,
10 tulips + 3 remaining red tulips = 13 tulips.
2. You can group 4 red tulips and 6 white tulips. This group of tulips consists of
4 red tulips + 6 white tulips = 10 tulips.
If there were 9 white tulips, then
9 - 6 = 3 white tulips left.
In total,
10 tulips + 3 remaining white tulips = 13 tulips.
