Answer:
Supplementary = two angle together is 180 degrees
Step-by-step explanation:
180-156= 24
24 degrees is X
So with this type of question, you are expected to solve the systems of equations simultaneously
Let 4x + 4y = -12 ..... (1)
3x - 4y = -23 ..... (2)
By summing (2) and (1)
⇒ 4x + 3x + 4y + (-4y) = -12 + (-23)
7x = -35
⇒ 7x ÷ 7 = -35 ÷ 7
⇒ x = - 5
By substituting x into (1)
If 4x + 4y = -12 ..... (1)
then 4 (-5) + 4y = -12
⇒ 4y = -12 + 20
⇒ y = 8 ÷ 4
⇒ y = 2
∴ the solution for the system of equation are x = - 5 ; y = 2
Answer:
x is the seats in the small van.
y is the seats in the large van = (x + 6). Since the large has 6 more seats.
Since the 2 vans can transport 57 people.
Small van makes 2 trips = 2x.
Large van makes one trip = (x + 6).
2x + (x +6) = 57
2x + x + 6 = 57
3x + 6 = 57
3x = 57 -6
3x = 51
x = 51/3
x = 17.
The larger van has (x + 6) = (17 + 6) = 23.
The larger van has 23 seats.
Step-by-step explanation:
Answer:
1. D: ( -4, 3 ) R: [ -1, 6 )
2. D: ( -oo, 5 ] R: ( -oo, oo )
