Name three non-collinear points. Please help :)
Answer: M, K, N
Step-by-step explanation: In order points to be non-collinear,
the points can't lie on the same line.
So what we are looking for are points that don't lie on the same line.
The correct answer would be points M, K, N.
Although M, K, R, and R, N, K, look like points that are non-collinear,
they aren't all points since R is the name of the plane.

Jacob wanted to purchase a boat. The dealership offered the following payment terms for Jacob: a $800 down payment and $275 a month for 36 months. If Jacob makes all the payments on time, he will be refunded $400. What will be the total cost of the boat, if Jacob makes all of his payments on time?
Answer:
$10,700
Step-by-step explanation:
The total cost of the boat if Jacob makes all of his payments on time is $10,300
The total cost of the boat is the sum of the total amounts paid less the amount refunded for swift payment
Total amount paid = $800 + ($275 x 36) =
$800 + $9900 = $10,700
Amount refunded = 400
Total cost = $10,700 - $400 = $10,300

What is the answer for this equation or problem? y+6=52 and what does y equal.
Answer: y=46
Step-by-step explanation:
Subtract 6 from either side to ensure that the y is alone. This then equals y=52-6.
52-6= 46
So therefore, y=46
Answer:
y=46
Step-by-step explanation:
We are given the equation:
y+6=52
and asked to solve for y. Therefore, we must isolate y on one side of the equation.
6 is being added to y. The inverse of addition is subtraction. Subtract 6 from both sides of the equation.
y+6-6=52-6
y=52-6
y= 46
Let’s check our solution. Plug 46 in for y and solve.
y+6=52
46+6=52
52=52
This checks out, so we know our solution is correct.
The solution to the equation y+6=52 is y=46
a shopkeeper sold watch allowing 15 percent dis.. and levying 13 percent vat .if the dis.. amount was rs 750 .find the vat amount
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \: Rs \: 552.5}}}}}[/tex]
Step-by-step explanation:
Given,
Discount percent = 15 %
Vat percent = 13 %
Discount amount = Rs 750
Vat amount = ?
Finding the Marked price ( MP )
[tex] \boxed{ \sf{Discount \: amount = \: discount\% \: of \: MP}}[/tex]
⇒[tex] \sf{750 = 15\% \: of \: MP}[/tex]

Equivalent expressions to an-1
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Write the expression 6 - 15 as an equivalent addition expression
Answer:
6 + (-15)
Step-by-step explanation:
6 - 15 would also be written as 6 + (-15). If you distribute the '+' into the '-15', you would get the negative 15.
1 * -15 = -15
So, 6 + (-15) would be the equivalent addition expression.

The quotient of a number t and 4.2 is at most 15.
Answer:
[tex]t \leq 63[/tex]
Step-by-step explanation:
Quotient of two numbers also means the result of the two numbers after division.
If the quotient of a number t and 4.2 is at most 15., this can be expressed using the inequality;
[tex]\dfrac{t}{4.2}\leq 15[/tex] (note that at most 15 means that the highest value we can have is 15 after taking the quotient of the number hence the reason of the inequality sign.)
On solving the inequality for the variable t
[tex]\dfrac{t}{4.2}\leq 15\\\\multiply \ both \ sides \ by \ 4.2\\\\\dfrac{t}{4.2}* 4.2\leq 15 * 4.2\\\\t \leq 63[/tex]
Hence t is at most 63
Which expression is represented by the diagram? ( Marked 1-4, I can't paste the question.)
Answer:
-6-(-1)
Step-by-step explanation:
Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6. Then since the last box is being taken away, we are subtracting it. The last box is still negative though so the last part is -1. Since -6 subtracted by -1 is -6-(-1), the answer is:
-6-(-1)

An angle measures 112º more than the measure of its supplementary angle. What is the
measure of each angle?
Answer:
The angles measure 34 degrees and 146 degrees.
Step-by-step explanation:
The supplement measures x.
The angle measures x + 112.
The measures of supplementary angles have a sum of 180 deg.
x + 112 + x = 180
2x + 112 = 180
2x = 68
x = 34
x + 112 = 146
The angles measure 34 degrees and 146 degrees.
Complete the table for the equation of the line y = 3x - 1 X
f(x)
-1
0
2
Answer:
Step-by-step explanation:
Given the equation of a line expressed as y = 3x-1, we are to find y = f(x) for the following values of x in the table.
If y = 3x-1, then f(x) = 3
When x = -1
f(-1) = 3(-1)-1
f(-1) = -3-1
f(-1) = -4
Hence when x = -1, f(x) = -4
When x = 0
f(0) = 3(0)-1
f(0) = 0-1
f(0) = -1
Hence when x = 0, f(x) = -1
When x = 2
f(2) = 3(2)-1
f(2) = 6-1
f(2) = 5
Hence when x = 2, f(x) = 5

Mario and Luigi want to purchase some extra controllers for their friends. Each controller costs $29.99. Use an algebraic expression to describe how much they will spend in total, before sales tax, based on purchasing the console, the number of games, and the number of extra controllers
Answer:
C = 299x + 59.99y + 29.99z
Step-by-step explanation:
An algebraic expression is an expression in which it involves the numbers like 1,2,3 also it includes the operations such as additions, subtraction, multiplication, etc
Fo mentioning an algebraic expression, we do have following components
x = number of consoles purchased
y = number of games purchased
z = number of controllers purchased
C = total cost
Also, the total cost would be equivalent to the sum of the price and then it multiplied with the numbers as stated above
So, the algebraic expression is
C = 299x + 59.99y + 29.99z

If the length,l, of the yard is 18 feet longer than the width ,w, of the yard, what is the area of the yard , in square yard
Answer: The area is [tex]w^{2}[/tex] + 18w
Step-by-step explanation:
We could represent the length of the yard by l = w+18 and the width as w .
And to find the area we will have to multiply the length by the width.
A= w(w+18 ) multiply
A= [tex]w^{2}[/tex] + 18w
Answer:
27^2 yards
Step-by-step explanation:
Perimeter = 2W + 2L ..... and the width is 18 more than the length....therefore
Perimeter = 2[L + 18] + 2L
72 = 2L + 36 + 2L
72 = 4L + 36 subtract 36 from each side
36 = 4L divide both sides by 4
9 = L and the width is 18 more = 27
So....the area = W x L = 27 x 9 = 243 ft^2 = 27^2 yards
(divide the area value by 9 )
