Answer:
25) A 26) B 27) y=-3/5-6 28) y=-15/18+4 29) y=5/4+12 30) y=-4x+3
Step-by-step explanation:
25) the line perpendicular would have the equation of y=-1/4x+b. In A, I plug in those to coordinated and they both have b as equal to -2 so they are both in the same line.
26) Find the slope of those two points (-1). Parallel lines means same slope but different y-intercepts and only B has a slope of -1.
27) Substitute those two points into the formula equation y=mx+b and solve for b
28) Solve for the slope and then solve for b by substituting
29) Write that equation into slope intercept form (y=5/4x-1). Parallel lines has the same slope but different y-intercepts. Use that slope of 5/4 and substitute those coordinates
30) Write the equation into slope intercept form (y=1/4x-5). Perpendicular lines have opposite reciprocal slopes. Find the opposite reciprocal of that slope and then substitute those coordinates

answer
n=3
The value of n is given by the equation n = 3
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2n = n + 3 be equation (1)
On simplifying the equation , we get
Subtracting n on both sides of the equation , we get
2n - n = 3
n = 3
Therefore , the value of n is 3
Hence , the equation is n = 3

The internal measures of a cuboidal room are 9m, 5m and 6m respectively. Find the total cost of
whitewashing all four walls of a room, if the cost of white washing is ₹ 5 per sq.m. What will be the cost of white washing if the ceiling of the room is also whitewashed.
Answers
Answer:
₹ 1290Step-by-step explanation:
The total surface area of the room = 2(LW + WH + LH)
TSA = 2(9*5 + 9*6 + 5*6)
TSA = 2(45 + 54 + 30)
TSA = 2(129)
TSA = 258
Hence the total surface area of the room is 258m²
If 1m² = ₹ 5
258m² = 5(258) = ₹ 1290
The cost of white washing if the ceiling of the room is also whitewashed is ₹ 1290

You must bye one hundred eggs with 100 cents. There are three types of eggs and you will need to buy all three types of eggs.Goose eggs must be bought in multiples of twenty. 1 chicken egg costs 5 cents 1 duck egg costs 1 cent 20 goose eggs costs 1 cent How many chicken, duck and goose eggs do you need to buy?
Answers
Answer:
1 duck egg
19 chicken eggs
80 goose eggs
Step-by-step explanation:
Given that:
Goose eggs must be bought in multiples of 20
20 goose eggs = 1 cent
1 chicken egg = 5 cents
1 duck egg = 1 cent
Total amount to spend = 100 cents
Total number of eggs to purchase = 100
In other to ensure that 100 cents is spent and 100 eggs is purchased :
Using logical analysis :
1 cent is spent on duck egg, so 1 duck egg is purchased
Goose eggs (sold in multiples of 20) for 1 cent each ; 4 cents is spent on (20 * 4) = 80 goose eggs
100 - (4 + 1) = 100 - 5 = 95 cents is spent on chicken eggs ; 95 / cost per chicken egg = 95 / 5 = 19 chicken eggs
Hence,
1 duck egg = 1 cent
(20 *4) goose eggs = 80 eggs ; 4 * 1 = 4 cents
19 chicken eggs = 19 * 5cent = 95 cents
(1 + 80 + 19)eggs = (1 + 4 + 95)cents
100eggs = 100centa
