Answer:
41.5
23.5
Step-by-step explanation:
Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:
x + y = 65
The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:
x - y = -18
Now solve equation B for x to get the revised equation B:
x = -18 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 65
-18+y+y=65
-18 + 2y = 65
2y = 83
y = 41.5
Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:
x + y = 65
x + 41.5= 65
X = 23.5
DIfference : 23.5 - 41.5 = 18
Sum: 41.5 +23.5 = 65
Hence, The two number are 23.5 and 41.5

Whats the range of the graph?
A- y= -1
B- y< -1
C- x> -1
D-x> 1
Other:________
Answer: Range is y > -1
Explanation:
The lowest point is where the open hole is. This is when y = -1. The open hole means we exclude it from the graph, so we can't reach y = -1
We can have any y value larger than -1 as part of the range. So the range is the set of y values such that y > -1
Side note: the domain is x > 1 for similar reasoning, but we're looking at the possible x values now.

Answer: A = 198.6cm²
Step-by-step explanation: The figure includes two semi circles on both ends. These can be solved as a whole circle with a diameter of 10cm because each semi circle is 5cm.
r = 10/2= 5cm
Area of circle:
A = πr²
A = 3.142*5²
A = 3.142*25
A = 78.55
A = 78.6cm²
The remaining section of the shape is a rectangle with a length of 12cm.
To get this, you subtract 10 from 22 because each semi circle is 5cm which adds up to 10cm.
The rectangle has a width of 10cm.
Area of rectangle:
A = lw
A = 12*10 = 120cm²
The total area of the shape:
A = 120 + 78.6
A = 198.6cm²

Step-by-step explanation:
Using Pythagoras' identity in right triangle ABD , then
AD² + BD² = AB² , substitute values
AD² + 12² = 15²
AD² + 144 = 225 ( subtract 144 from both sides )
AD² = 81 ( take square root of both sides )

Que pase por el punto ( 2 , 3 ) y es perpendicular a la recta x − 4 y + 1 = 0
Answer:
y = -4x+11
Step-by-step explanation:
x − 4 y + 1 = 0
x+1 = 4y
4y = x+1
y = 1/4x+1/4
pendiente de una recta perpendicular es el recíproco negativo
negative reciprocal 1/4x is -4x
y = -4x+1/4
Con la nueva pendiente, use la forma de intersección de la pendiente y el punto para calcular la intersección usando (2,3) :
y = mx + b or y = -4x+b
3 = -4(2) + b
3 = -8 + b
11 = b
b = 11
y = -4x+11

What is profit?
Profit is a financial benefit that is realized when the amount of revenue gained from a business activity.
Given
|Soccer nets per day | Total Cost | Total Revenue |
| 1 | 7$ | $30 |
| 2 | 9$ | $60 |
| 3 | 10$ | $90 |
| 4 | 11$ | $120 |
| 5 | 13$ | $150 |
The total cost in the four soccer = $11
The total revenue in the four soccer = $120
The profit does the company make from producing and selling four soccer nets is;
[tex]\rm Profit = Total \ revenue -Total \ cost\\\\Profit= 120-11\\\\Profit = 109[/tex]

Marcel and Floyd are playing games at an arcade. Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games. Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining. Jorge's work is shown below.
Given that,
Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games.
Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining.
The attached figure shows the equation that Jorge had :
8.25-0.25x=9.75-0.75x
Subtract 9.75 to both sides
8.25-0.25x-9.75=9.75-0.75x-9.75
-1.5-0.25x=-0.75x
Add 0.25x to the both sides,
-1.5-0.25x+0.25x=-0.75x+0.25x
-1.5=-0.5x
⇒ x = 3
Jorge is incorrect at step 2 where he taken -0.25x to the RHS such that -0.75x+0.25x, he get 0.5x instead of (-0.5x). Hence, From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.

Equilateral triangle ABC is inscribed in circle X. What is the measure of arc CB?
===========================================================
Explanation:
An equilateral triangle has three sides of the same length, which in turn means that the curved arc pieces AB, BC and AC are the same length (but longer than each side of the triangle).
Furthermore, it leads to the fact that we split a 360 degree circle into three equal portions of 360/3 = 120 degrees each.
Imagine we drew in the line segments AX, BX, and CX. This splits the circle into 3 equal pie slices. Central angle BXC is 120 degrees because of the earlier calculation done before.

Jacobs school is selling tickets to a fall musical. First day of ticket sales the school sold 28 tickets. If adult tickets cost $8 each and child tickets cost $5, how many adult and child tickets were sold? Total ticket sales: $176
Answer:
12 adult tickets, 16 child tickets
Step-by-step explanation:
x is the amount of adult tickets
y is the amount of child tickets
----------------------------------------------------------
lets make 2 equations:
1) x + y = 28
2) 8x + 5y = 176
----------------------------------------------------------
now we can substitute either x or y into the second equation so that we only have to deal with one variable at once.
x + y = 28
subtract y from each side:
x + y - y = 28 - y
which gives you:
x = 28 - y
-------------------------------------------------------
Then we plug that into the second equation, which will give us:
8(28 - y) + 5y = 176
now you want to expand 8(28 - y), so you use the distributive property.
8(28 - y) = 8*28 - 8*y = 224 - 8y
now that we have solved that, plug it back into the equation:
224 - 8y + 5y = 176
subtract 224 from each side:
224 - 8y + 5y - 224 = 176 -224
which gives us:
-3y = -48
now if you multiply each side by ( -1 ) you get:
3y = 48
now divide both sides by 3 and you get:
y = 48 / 3
48 / 3 is 16
y = 16
-------------------------------------------------------------------------------
now plug y = 16 into equation 1
equation 1 was x + y = 28
plug 16 in for y which gives us:
x + 16 = 28
subtract 16 from both sides
x + 16 - 16 = 28 - 16
Which finally gives us
x = 12
---------------------------------------------------------------------------------
Remember:
x is the amount of adult tickets
y is the amount of child tickets
x = 12 means that 12 adult tickets were sold
y = 16 means that 16 child tickets were sold
----------------------------------------------------------------------------------

He walks 5/6 of a mile each day.
Multiply the distance each day by the number of days:

When multiplying a fraction by a whole number, multiply the numerator ( top number) by the whole number and leave the denominator ( bottom number as is)
5/6 x 5 = (5 x5)/6 = 25/6 now rewrite as a proper fraction:
