Answer:
x = 7
Step-by-step explanation:
( x +16)° = (4x - 5)°
x + 16 = 4x - x
16 + 5 = 4x - x
21 = 3x
7= x
hence, x =7
Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
Multiply both sides by sin(80)
172.274641 = x
x = 172.27 in. (to 2 decimal places)

Answer:
124 million in 2007
Step-by-step explanation:
This is a proportion match question, we consider 121-116 to represent a 9 year change = 5 rate of change per 9 years. We need to find one year so we divide 5/9=0.55 per year growth. =2002- 2007= 0.55 million x 5 = 2.8million growth add 121 million = 121 =123.8 in 2007 = 124 million to nearest m.
Answer:
-12x - 10 or -2(6x +5)
Step-by-step explanation:
4x + 10 - 4(-4x + 5)
first, distribute the -4 among the parentheses
4x + 10 - 16x - 20
combine like terms
-12x - 10
if they want you to take it further, take out a -2
-2(6x + 5)
