Answer:
estimate: $80
exact amount paid: $82
Step-by-step explanation:
If you round $246 to 240, then divide it by 3, you should get $80. The cost per pair should be around $80 each
For the exact answer you take the amount spent (246) and divide it by the amount of jeans she bought (3).
246/3 = 82
Last month you spent $20 on clothing. This month you spent 180% of what you spent last month. How much did you spend this month?
Does an isosceles triangle have three congruent sides?
Answer:
It can... an isosceles triangle by definition has two or more congruent sides. An equilateral triangle will always have three congruent sides. An equilateral triangle will always be an isosceles triangle but an isosceles triangle will not always be an equilateral triangle. I hope this helps!

The number of hours, h, that Mr. Hampton works varies directly with the number of tasks, t, he has to perform. If he has 6 tasks to perform and works for 15 hours, what is k the constant of variation?
i think its 2.5 because 15/6= 2.5 so 2.5t=h and the equation is kt=h so 2.5 makes the most sense.

A quadratic equation is in the form of ax²+bx+c. The solution of the given quadratic equation is 2 and -5.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Given the quadratic equation x²+3x-10=0, the solution to this equation can be done as shown below.
x² + 3x - 10 = 0
Keep x terms on the left and move the constant to the right side by adding it on both sides,
x² + 3x = 10
Take half of the x term and square it,
x = (3/2)² = 9/4
Then add the result to both sides
x² + 3x + (9/4) = 10 + (9/4)
Combine terms on the right,
(x + 3/2)² = 49/4
Taking under root,
x + 3/2 = ± 7/2
Now,
x = 7/2 - 3/2 = 2
x = -7/2 - 3/2 = -5
Hence, the solution of the given quadratic equation is 2 and -5.

IM DESPERATE FOR AN ANSWER Customers of a phone company can choose between two service plans for long distance calls. The first plan has an $18 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has no monthly fee but charges $0.17 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
450 minutes
Step-by-step explanation:
1st plan
18 + 0.13x = y
2nd plan
0.17x = y
x is minute of calls
y is the total price customers must pay
both of them equal as y = y
y = y
18 + 0.13x = 0.17x
18 = 0.17x - 0.13x
18 = 0.04x
x = 18/0.04
x = 450 minutes
can you figure how much they should pay?

1) Through any two points, there is exactly one line.- postulate
2) A line segment is a part of a line and is bounded by two endpoint. - Definition
3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem
What are postulates?"These are statements that are assumed to be true without proof."
What is definition?"It is used to give a precise meaning to a new term."
What is theorem?"It is a statement that can be proved to be true by accepted mathematical operations and arguments"
For given question,
We have been given three statements.
We need to classify them as theorem, postulate and definition.
The first statement is 'Through any two points, there is exactly one line.'
We know that this is the fundamental postulate use in Geometry.
The second statement is 'A line segment is a part of a line and is bounded by two endpoint.'
Above statement is the definition of line segment.
The last statement is 'If two lines intersect, then each pair of opposite angles are congruent.'
We can prove above statement by using Euclid's axiom.
So, above statement is a theorem.
Therefore, 1) Through any two points, there is exactly one line.' - postulate
2) A line segment is a part of a line and is bounded by two endpoint. - Definition
3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem

Answer:
The answer would be (-1,7)
Step-by-step explanation:
Using the process of elimination we can subtract the two equations to cancel out the y variable. That is subtract the second equation from the first.
3x + y = 4
- 2x + y = 5
x = -1
Now that we have found x we can substitute -1 for x into any equation for y. So, in substituting -1 for x in the second equation we get:
2(-1) + y = 5
-2 + y = 5
y = 5 + 2
y = 7
ANSWER: (-1, 7)

Answer:
x=13
z=79
Step-by-step explanation:
The angles given are supplementary. This means that when added their sum will be 180. So add the 2 expressions together and set them equal to 180.
This looks like, (8x-25)+(6x+23) = 180. Then, combine like terms in the equation to get the next step, 14x-2 = 180. Next, add 2 to both sides. Finally, divide both sides by 14.Therefore, x=13Then, you have to find z. The angle z is congruent to the angle with the measure (8x-25). This is because they are vertical angles, and therefore congruent. So, plug 13 into the expression, 8(13)-25=79 degrees. Since that angle equals 79, z must also equal 79.

Use the table to work out the values of a , b , c , and d .
Answer:
a = 16, b = 6, c = - 4, d = - 9
Step-by-step explanation:
Substitute the appropriate values of x into the equation and evaluate.
x = - 3 : y = 1 - 5(- 3) = 1 + 15 = 16 → a
x = - 1 : y = 1 - 5(- 1) = 1 + 5 = 6 → b
x = 1 : y = 1 - 5(1) = 1 - 5 = - 4 → c
x = 2 : y = 1 - 5(2) = 1 - 10 = - 9 → d
Answer:
a=16; b=6, c= -4, d= -9
Step-by-step explanation:
[tex]f(x)=1-5x\\f(-3) = 1-5(-3)=1+15=16\\f(-1) = 6\\f(1)=-4\\f(2)=-9[/tex]
