Saskia is solving an equation in one variable and gets the equivalent equation 3=3. Assuming her work is correct, what can she conclude about the original equation?
Answers
Answer:
The second option is correct. There are infinitely many solutions.
Step-by-step explanation:
Let's use the equation x + 3 = x + 3
We can simplify this two ways: x = x, or 3 = 3
We can use any value of x so that both sides are equivalent to each other.
For example:
x + 3 = x + 32 + 3 = 2 + 35 = 5or
x + 3 = x + 3-3 + 3 = -3 + 30 = 0As you can see, both sides of the equations are always the same with any value of x.

How do I solve this proportional problem?
Phone 1 has the length of 2.6 and height of 5.4
Phone 2 has the height of 6.21 and the length of _____
What is the length of the Phone 2? Keep in mind that the answer is gonna to proportional.
Answers
If the phone goes from 5.4 to 6.21 then to find the proportional relationship we divide 6.21/5.4 which equals 1.15 and then multiply 1.15 x 2.6 which equals 2.99
I’m really bad at explaining sorry
The length of the phone 2 is 2.99 units.
Given data:
Phone 1 has the length of 2.6 and height of 5.4
Phone 2 has the height of 6.2 units.
The length of the phone 2 is represented as L.
So, the lengths and heights are in proportion.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
So, [tex]\frac{6.2}{5.4} =\frac{L}{2.6}[/tex]
On cross multiplying:
L = 1.15 * 2.6
L = 2.99 units.
Hence, the length is 2.99 units.

92 x 49 = 4508 which is the area of the rectangle because you do length times height.
To Find the area of a circle you need to find the radius which is half of your diameter which is 20
20/2=10
Then for the area of your circle the formula is Pie r squared (π r^2)
Plug into your calculator π x 10^2 to get 314.16
Finally you subtract 314.16 from 4508 to get your answer 4193.84

x = 18
Step-by-step explanation:
The given angle is a right-angled triangle.
Such triangles have an angle that equals 90°.
The square attached at the base represents 90°. [Whenever you such a square between two sides, simply put the angle between those sides equal to 90.]
So, the points we know about this triangle:
One angle is = 90Another angle given in the question is 72°.*Property*
The sum of all angles in a triangle = 180
==> 90 + 72 + x = 180
==> 162 + x = 180
==> x = 180 - 162
==> x = 18
