The first night in a hotel costs 40 dollars. All additional nights cost 27 dollars. How many nights did we stay
at this hotel if the total bill was 148 dollars?
Answer:
5
Step-by-step explanation:
First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)
Answer:
4 nights
Step-by-step explanation:
148-40=108
108÷27=4
So, you spent 4 nights at the hotel.

What type of quadrilateral is ABCD? Move segments and words to blanks to classify quadrilateral ABCD
The quadrilateral that is illustrated based on the information and diagram is a square.
What is a quadrilateral?A quadrilateral is a plane figure with four edges and four corners, also known as vertices. The quadrilateral's four vertices or corners all have angles. A quadrilateral has four straight sides and is a two-dimensional shape. Parallelograms, trapezoids, rectangles, kites, squares, and rhombuses are a few examples of quadrilaterals.
A quadrilateral with four equal sides and angles is called a square. Due to its equal sides and angles, it is also a regular quadrilateral. A square has four 90° angles, just like a rectangle does. It can also be thought of as a rectangle with equal lengths on its two adjacent sides. A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral.

Jake lives 2⅓mile from school. He decides to walk to the shop on his way home. The shop is 1⅜mile from school. A) What is the shortest possible distance from the shop to his home? B) What is the largest possible distance from the shop to his home?
Answer:
Shortest distance = 23/24
Farthest distance = 3 17/24 miles
Step-by-step explanation:
Distance of home from school = 2 1/3 miles
Distance of shop from school = 1 3/8 miles
Shortest distance possible :
(2 1/3 - 1 3/8) miles
(7/3 - 11/8) miles
L. C. M = 24
(56 - 33) / 24
23 / 24 miles
The farthest distance :
(2 1/3 + 1 3/8) miles
(7/3 + 11/8) miles
L. C. M = 24
(56 + 33) / 24
89 / 24
= 3 17/24 miles
The vertex form of the equation of a parabola is y = 5(x-3)2 - 6.
What is the standard form of the equation?
9514 1404 393
Answer:
y = 5x² -30x +39
Step-by-step explanation:
Multiply it out and collect terms.
y = 5(x -3)² -6
y = 5(x² -6x +9) -6 . . . . . expand the square
y = 5x² -30x +45 -6 . . . . use the distributive property
y = 5x² -30x +39 . . . . . . collect terms
_____
The expansion of a binomial square is ...
(a +b)² = a² + 2ab + b²
In this problem, we have a=x, b=-3.

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5

Answer:
x,y =3,-4
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 10
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-10) = 17
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-10
// Use the x value to solve for y
y = 2(3)-10 = -4
