What's 2 + 2 in a mathematical sense
In a mathematical sense..
Not to make it too complicated, however, here's where we get on to the real mathematics.
There are infinite equations for 2 + 2. The gap between any number can be infinite if you keep giving it more numerical content. However, solving 2 + 2 can be very tricky.
1 + 1 + 1 + 1 = 4. Easy, right? Wrong. We can deduct from this equation that 1 + 1 = 2, so if we do 1 + 1 PLUS 1 + 1, (1 + 1 + 1 + 1 again), that equals four, because 1 + 1 is 2 and if we add another 1 to 2, 1 + 2, it equals 3, so 1 + 3 = 4. I'd like to remind you-- this works both ways, whether or not it's 3 + 1 or 1 + 3, it equals 4. If we carry the 1 from the three and put it in a separate number in an equation, said equation is now 1 + 1 + 2. It still equals 4, because 1 + 1 = 2 and if you take 2 and put it in 1 + 1's place, it's 2 + 2.
2 + 2 = 4.
(this was a joke answer, don't take anything said in this answer seriously.. OR you can if you want, because it's all true.. 2 + 2 = 4.)
Hope this helped!

. Solve for x
10 = 5(x + 8)
Answer:
x = -6
Step-by-step explanation:
10 = 5(x+8)
=> 5(x+8) = 10
=> 5x + 40 = 10
=> 5x = 10 - 40
=> 5x = -30
=> x = -30/5
=> x = -6
0.6x + 2.7 = 0.9x
"solve the equation. show all your steps"
Answer:
x=9
Step-by-step explanation:
0.6x+2.7=0.9x
move the terms
0.6x-0.9x=-2.7
collect like terms
-0.3x=-2.7
divide both sides
x=9

Answer:
118.73
Step-by-step explanation:
Answer:
118.74 ft²
Step-by-step explanation:
First, you're going to get the are of the following shapes, one by one.
Area of A Circle = πr²
Area of a Rectangle = bh
Area of a Square = s²
Step 1: Let's find the area for the Circle.
Diameter = 6
Radius = Diameter ÷ 2
6 ÷ 2 = 3
The Radius is 3.
A = (3.14)(3)²
Simplify:
(3.14)(9) = 28.26 ft²
Step 2: Find the Area of the Rectangle.
A = bh
11 × 2 = 22
Area of Rectangle = 22 ft²
Step 3: Find the Area of the Square
A = s²
13² = 13 × 13 = 169 ft²
Step 4: Subtract the Aea of the Circle and Rectangle form the Are of the Square.
169 - 28.26 - 22 = 118.74 ft²
For what value of x is the rational expression below equal to zero?
(x+5)(x - 1)
A. 4
ОО
B. 1
C. -5
d
D. -4
SUBMIT
Answer:
I can only guess that by x^2-2x-24 you mean the entire denominator. In cases like this is is important to use parentheses to remove any doubts. For example:
(x+8) / (x^2-2x-24).
This rational expression is undefined at any x for which the denominator, x^2-2x-24, is zero.
x^2-2x-24 factors into (x+4)(x-6). The roots are -4 and +6.
Thus, the given expression is undefined at {-4,6} (set notation).

A girl 1.0 m in height, standing on top of a vertical building 45.0 m high sees a car some distance away when the angle of depression is 55 degree. What distance is the car from the base of the building?
The distance is the car from the base of the building is 32.21m.
The building forms a right angled triangle. Check the attached image for the diagram of the right-angled triangle.
The height is 45 + 1 = 46m
The base is what we are to determine.
Remember SOHCAHTOA.
We have the length of the opposite side and we are to determine the length of the adjacent side. So, we would use Tan
Tan = opposite / adjacent
Tan 55 = 46 / adjacent
1.42814 = 46 / adjacent
adjacent = 46 / 1.42814
= 32.21 m

What is meant by the order of operations?
Answer:
Step-by-step explanation: The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
The rectangle shown has a perimeter of 148 cm and the given area. Its length is 8 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
System of equations:
L = 5W + 7
2W + 2L = P
L = 62 cm
W = 11 cm
Step-by-step explanation:
Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.
The formula for perimeter of a rectangle is: 2W + 2L = P, where W = width and L = length. We also know that the L is '7 more than five times its width'. This can be written as: L = 5W + 7. Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:
2W + 2(5W + 7) = 146
Distribute: 2W + 10W + 14 = 146
Combine like terms: 12W + 14 = 146
Subtract 14 from both sides: 12W + 14 - 14 = 146 - 14 or 12W = 132
Divide 12 by both sides: 12W/12 = 132/12 or W = 11
Put '11' in for W in the equation for 'L': L = 5(11) + 7 or L = 55 + 7 = 62.

The equation 180 - X= 132 represents
the number of stamps in Colin's collection,
Solve the equation for X.
Answer:
x = 48
Step-by-step explanation:
equation:
180 - x = 132
subtract 180 from each side:
180 - 180 - x = 132 - 180
-x = -48
divide both sides by -1:
[tex]\frac{-x}{-1} = \frac{-48}{-1}[/tex]
x = 48
to check, substitute 48 for x:
180 - x = 132
180 - 48 = 132
132 = 132

Answer:
let cost of washer be x
cost of dryer be $745-x
we have
cost of washer =$95+($745-x)
x=$95+$745-x
x+x=$840
2x=$840
x=$840/2=$420
the cost of washer =$420
cost of drier=$745-x=$745-420=$325
$325 is the cost of dryer.
