Answer:
Step-by-step explanation:
2x + 3 = 1
Collecting like terms
2x = 1 - 3
2x = -2
x = -2/2
x = -1
3 < k
Step-by-step explanation:
Simplify by undoing addition to both sides, then divide both sides by the coefficient of k.
Answer:
x = 30°
Step-by-step explanation:
So the total angle of a quadrilateral is 360°.
Your goal is to find x which associate numbers in each corner.
The equation to the quadrilateral is this:
a + b + c + d = 360°
a = ∠ABC = 4x
b = ∠BCD = 3x
c = ∠CDA = 2x
d = ∠DAC = 3x
∠ABC + ∠BCD +∠CDA + ∠DAB = 360°
4x + 3x + 2x + 3x = 360°
7x + 5x = 360°
12x = 360°
x = 360 ÷ 12
x = 30°

Answer:
Combined equation is 
Step-by-step explanation:
a varies directly as b and inversely as c.
This can be written as
a =
a = kb
where k is the proportionality constant
-------------------------------------(1)
Now lets find the k value bu substituting the given a, b,c values


36 = 12 k

k = 3
Thus the eq(1) becomes

Let us now find the value of a when b=7 and c = 3


a = 7
