x = 12 * 7/2
x=84/2
x=42
2X-Y=4
x=4-y
please explain each step
Step-by-step explanation:
2X-Y=4 ---------(1)
x=4-y---------(2)
since x = 4 – y just substitute for eqn 1
2(4–y) – y = 4
8 – 2y –y=4
8 –3y = 4
–3y=4–8
–3y=–4
y=–4/–3
y= 4/3
since y = 4/3 just substitute for y in eqn (2)
x=4–4/3
multiply both sides by 3
3x=12–4
3x=8
x=8/3 or 2 2/3

Find the midpoint of the segment with the following endpoints
(5,5) and (1,1)
The midpoint of the segment given (5,5) and (1,1) is (3, 3).
What is midpoint?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Coordinates of the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂)= [(x₁ + x₂)/2 , (y₁ + y₂)/2].
The midpoint of the line segment with endpoints (5,5) and (1,1)
= [ ( 5 + (1))/2 , ((5) + 1)/2 ]
= [ (6)/2 , 6/2 ]
= [ 3, 3
Therefore, the midpoint of the line segment with endpoints is (3, 3).

Answer:
The second company should get the contract.
Question
The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway.
Reason
Based on the least expensive price per mile per year, the second company should get the contract. This is because the price per mile per year for the second company is lower than the price per mile per year for the first company.
The first company gives a bit of $120,000 per mile and will guarantee the web for eight years. The second company bids the word for $150,000 per mile using a new asphalt material made from used tires.

A concrete drain is 10m long, with an outside diameter of 1m and an inside diameter of 0.8m. Determine the volume of the concrete required to make the drain, to the nearest tenth of a cubic metre
Answer: To calculate the volume of the concrete required to make the drain, we need to find the volume of the cylinder formed by the outside diameter of the drain and subtract the volume of the cylinder formed by the inside diameter of the drain.
The formula for the volume of a cylinder is:
V = πr^2h
where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.
The radius of the base of the outside cylinder is 0.5m (the diameter of 1m divided by 2) and the height is 10m. The radius of the base of the inside cylinder is 0.4m (the diameter of 0.8m divided by 2) and the height is also 10m.
So the volume of the outside cylinder is:
V = π * 0.5^2 * 10 = 15.7 m^3
and the volume of the inside cylinder is:
V = π * 0.4^2 * 10 = 12.6 m^3
To find the volume of the concrete required to make the drain, we subtract the volume of the inside cylinder from the volume of the outside cylinder:
15.7 m^3 - 12.6 m^3 = 3.1 m^3
So the volume of concrete required to make the drain is approximately 3.1 cubic metres. To the nearest tenth of a cubic metre, this is 3.1 m^3.

Sharon started with $42 in her bank account and
added $16 per week. Neil started out $70 in debt and deposited $30 per week. Determine how many weeks it will take them to have saved the same amount of money.
Answer:
8 weeks
Step-by-step explanation:
The two equations I got from this are y=16x+42 and y=-70+30x
I graphed both equations online to see what the intersection would be the intersection between both equations is (8,170). I think that this means that in 8 weeks they would both be at 170 dollars, so I think that it will take them 8 weeks to have the same amount of money saved

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Sharon began with $42 in her financial balance and added $16 each week. Neil began $70 underwater and kept $30 each week.
Let 'x' be the number of weeks and 'y' be the total amount. Then the equations are given as,
y = 16x + 42 ...1
y = 30x - 70 ...2
From equations 1 and 2, then we have
30x - 70 = 16x + 42
14x = 112
x = 8

Step-by-step explanation:
1. -2y + 7 = -5
-2y + 7 - 7 = -5 - 7
-2y = -12
y = 6
2.-3(x + 5) = -9

The value of the angles of the given quadrilateral are;
8) ∠X = 124° = ∠W
∠Y = 56° = ∠Z
9) ∠J = 44° = ∠K
∠L = 136° = ∠M
How to find the angles of a quadrilateral?The sum of angles of a quadrilateral is equal to 180 degrees. Now, in the quadrilateral given, the two angles on the slant side always equal 180 degrees. Thus;
8) From the given trapezium, we can use the definition above to say that;
∠X + ∠Y = 180°
Thus;
(13x - 7)° + (8x - 2)° = 180°
21x - 9 = 180
21x = 189
x = 189/21
x = 9
Thus;
∠X = (13(9) - 7)°
∠X = 124° = ∠W
∠Y = 180° - 124°
∠Y = 56° = ∠Z
9) From the above, we can apply the same to this quadrilateral to get;
7x + 2 + 25x - 14 = 180
32x - 12 = 180
32x = 180 + 12
32x = 192
x = 192/32
x = 6
∠J = (7(6) + 2)
∠J = 44° = ∠K
∠L = 180 - 44
∠L = 136° = ∠M

The nth term of the given quadratic sequence is 2n².
What is quadratic sequence?
The ordered sets of numbers known as quadratic sequences are based on the rule n^2 = 1, 4, 9, 16, 25,.... (the square numbers). Every quadratic sequence has a n^2 term.
Consider, the given quadratic sequence
2, 8, 18, 32, 50, ...
we have to find nth term of this quadratic sequence ; 2 , 8 , 18 , 32, 50, ...
To find the nth term, we have to find the relation between the given terms.

The sum of three consecutive integers is 42. Which of the equations could represent this relationship? Select the two correct answers. x + (x + 1) + (x + 2) = 42 x + (x + 2) + (x + 4) = 42 (x minus 1) + x + (x + 1) = 42 (x minus 2) + x + (x + 2) = 42 x + 2 x + 3 x = 42
The two equations that can represent the relationship is
i. x +( x+1) + (x+2) = 42 and
Ii. (x-1) +x + (x+1) = 42 ( option A and C)
What are consecutive integers?Consecutive integers are those numbers that follow each other. They follow in a sequence or in order. For example, a set of natural numbers are consecutive integers.
For example, 4,5,6,7 are consecutive integers. This means that the difference between two consecutive numbers is 1.
If the first number is x, then the second number is (x+1 ) and the third number is (x+3)
The sum of the three number is x +( x+1) + (x+2) = 42
if the second number is x, then the first number is (x-1) and the third number is x+1
Therefore the sum of the three numbers can also be written as (x-1) +x + (x+1) = 42
