Answer:
a = -0.6b + 0.2c
Step-by-step explanation:
Simplifying
5a + 3b = c
Solving
5a + 3b = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3b' to each side of the equation.
5a + 3b + -3b = -3b + c
Combine like terms: 3b + -3b = 0
5a + 0 = -3b + c
5a = -3b + c
Divide each side by '5'.
a = -0.6b + 0.2c
The amount he will get on that day = the guaranteed wage + the amount of table he waits x 14
So, Marques expect to make 25 + 14 x 17 = 25 + 238 = $263
The correct answer would be (C.) x>90
2.5 plus 13.5 times 10
Hope that helps
Answer:
Step-by-step explanation:
cot²(3x)=y
y²-3y+2=0
y²-y-2y+2=0
y(y-1)-2(y-1)=0
(y-1)(y-2)=0
y=1,y=2
cot3x=1
tan 3x=1=tan (π/4)=tan (nπ+π/4)
3x=nπ+π/4=(4nπ+π)/4=(4n+1)π/4
x=(4nπ+1)π/12,n is an integer.
cot 3x=2
tan 3x=1/2
3x=tan^{-1}(1/2)≈26.57°+360n
x≈8.86°+120n
