Answer:
no solution
Step-by-step explanation:
3x - 7x - 16 = -4x + 5 - 16
combine like terms
-4x - 16 = -4x - 11
move the terms with variables to one side and constants to the other
add 4x to move it
-4x + 4x = 0
-16 = - 11
this is not possible so there is no solution
Answer:
0=5
Step-by-step explanation:
3x - 7x - 4x + 5 - 16
-4x - 16 = -4x + 5 -16
-4x - 16 = -4x -11
-4x -16 + 16 = -4x - 11 + 16
-4x = -4x + 5
-4x + -4x = -4x + 5 + 4x
combine like terms
repeat that
0 = 5

The values of x, y, and z. The diagram is not to scale.
x=67z =113y=55This is further explained below.
What are the values of x, y, and z. The diagram is not to scale.?Generally, Angle in a triangle is 180^{\circ}
Therefore
45+68+x=180
x=180-(45+68)
x=67
The angle on a line is also 180^{\circ}
x+z =180
67+z =180
z =180-67
z =113
In conclusion
180=113+12+y
-180-(113+12)=y
y=55

An aeroplane when flying at a height of 2000m from the ground passes vertically above a helicopter at an instant when their angles of elevation from the same point on the ground are 60⁰ and 30 respectively. Find the vertical distance of the helicopter from the ground.
The vertical distance of helicopter from the ground is equal to 2000 / 3 m.
Let the distance between the two planes A and B be x.
In △ ADC, we get that:
tan 60° = 2000 / y
√3 = 2000 / y ...(1)
Now, in △ BCD, we get that:
tan 30° = 2000 - x / y
1 / √3 = (2000 - x) / y ... (2)
Divide (1) from (2):
3 = 2000 / (2000 - x)
6000 - 3 x = 2000
3 x = 6000 - 2000
3 x = 4000
x = 4000 / 3
(2000 - x) = 2000 - 4000/3 = 2000 / 3
Therefore, the vertical distance of helicopter from the ground is equal to 2000 / 3 m.

Given data
50 vehicles belong to an enterprise that has three departments, A, B and C
6 vehicles are available for the use of all three departments
2 vehicles give service to neither of the departments
24 vehicles are administrated by department B
16 of the 24 used by B are also used by the others departments
There are twice as many vehicles in department A as there are in department C.
equal numbers of vehicles are allocated when used by any two departments
How to find the number of vehicles administrated by each departmentnumber of vehicles on department A = 2 * number of vehicles in department C.
say A = 2C
B = 24
let x represent the number of vehicles used by any two departments
16 of the 24 used by B are also used by the others departments and equal numbers of vehicles are allocated when used by any two departments hence
16 = 2x + 6
2x = 16 - 6
2x = 10
x = 5
B only = 24 - 2x - 6 = 18 - 2x = 18 - 10 = 8
A only = A - 2x - 6 = 2C - 10 - 6 = 2C - 16
C only = C - 2x - 6 = C - 10 - 6 = C - 16
adding up all the vehicles as allocated to get to the sum of 50
24 - 2x - 6 + A - 2x - 6 + C - 2x - 6 + x + x + x + 6 + 2 = 50
24 - 6 - 6 - 6 + 6 + 2 - 2x - 2x - 2x + x + x + x + A + C = 50
24 - 10 - 6x + 3x + 2C + C = 50
14 - 3x + 3C = 50
3C - 3X = 50 - 14
3C - 3(5) = 36
3C - 15 = 36
3C = 36 + 15 = 51
C = 17
C only
C only = C - 16
C only = 17 - 16
C only = 1
A only
A only = 2C - 16
A only = 2 * 17 - 16 = 34 - 16 = 18
The number of vehicle administered by department A only = 18

Given: g(x)=√x-4 and h(x) = 2x - 8.
What is g(h(10))?
O 2√2
√6
√6-8

The value of g(h(10)) is 2√2. the correct option is A.
Given that the functions are g(x)=√x-4 and h(x)=2x-8.
A function is defined as the relationship between a set of inputs where each input has an output.
Firstly, we will find the value of h(10) by substituting x=10 in the function h(x)=2x-8.
h(10)=2(10)-8
h(10)=20-8
h(10)=12
Now, we will find g(h(10)) where h(10)=12.
By substituting h(10)=12 in g(h(10)), we get
g(h(10))=g(12).
Further, we will find g(12) by substituting x=12 in the function g(x)=√x-4, we get
g(12)=√(12-4)
g(12)=√8
g(12)=2√2
Hence, the value of function g(h(10)) when g(x)=√x-4 and h(x)=2x-8 is 2√2.

Answer:
Step-by-step explanation: Let x be the smaller and y be the largest number.
Since x+y=13, we deduce y=13-x
Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x
Their sum is y+2+2x
And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x

The cost of gas in England is 96.4 pound sterling/liter is 549.1185 U.S. dollars/gallon
The cost of gas in England is 96.4 pound sterling/liter.
3.875 liters = 1 gallon
1 liter = 1/3.875 gallon
1.47 US$= 1 pound sterling
pound sterling / liter = 1.47/(1/3.875)) U.S. dollars/gallon
= (1.47)(3.875) U.S. dollars/gallon
96.4 pound sterling / liter = (96.4)(1.47)(3.875) U.S. dollars/gallon
= 549.1185 U.S. dollars/gallon

The intersection of Sets :
The intersection of sets for two given sets is the set that contains all the elements that are common to both sets. The symbol for the intersection of sets is "∩''. For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets, and are the common elements of A and B.
Intersections of sets have properties similar to the properties of numbers. The properties of the intersection of sets include the commutative law, associative law, the law of null set and universal set, and the idempotent law. The following table lists the properties of the intersection of sets.
Name of Property/Law Rule
Commutative Law A ∩ B = B ∩ A
Associative Law (A ∩ B) ∩ C = A ∩ (B ∩ C)
Law of ϕ and U ϕ ∩ A = ϕ , U ∩ A= A
Idempotent Law (A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)
(A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C)
Important Notes:
(A ∩ B) is the set of all the elements that are common to both sets A and B.
If A ∩ B = ϕ, then A and B are called disjoint sets.

In triangle ABC, the size of angle B is 3 times the size of
angle A, and the size of angle C is 16° less than 6 times
the size of angle A.
Find the size of the angles.
Step-by-step explanation:
Here,
angle B = 3 x angle A
angle C = 6 x angle A - 16
now, for a triangle,
angle A + angle B + angle C = 180
or, angle A + 3 x angle A + 6 x angle A - 16 = 180
or, 10 x angle A = 196
so, angle A = 19.6 degrees
angle B = 3 x 19.6 = 58.8 degrees
angle C = 6 x 19.6 - 16 = 101.6 degrees
