x<-5
Step-by-step explanation:
-3x<12+3
3x>15 divide both sides with ÷3
x<-5
XE(-œ,-5)
Answer:
It depends, see answer below
Step-by-step explanation:
By arithmetic, we refer to the elementary operations between numbers. You can build the integer, rational, real and complex number systems from the natural numbers, so it is enough to obtain arithmetic for natural numbers.
In the axiomatic formulation of natural numbers, you assume that there exists a non empty set N such that multiplication and addition are defined in N with the commutative, associative, distributive and modulus properties. If you take this approach, you need all of the above: Numbers exist, Multiplication, Addition.
A different approach is the following: assume the Peano axioms: The set of natural numbers exists, and it obeys an inductive structure (without going in further details, every natural number has a unique sucessor, and mathematical induction is valid). You can define addition and multiplication inductively, so in this case you only need to assume that numbers exist.
Answer:
If an angle of 1 isosceles triangle is congruent to an angle of another isosceles triangle the triangles are similar. sometimes If the corresponding sides of 2 similar triangles are in a ratio of 3:4 then the there perimeters are in a ratio of 3:4.

Answer:
I think it's 2 out of 4
Step-by-step explanation:
I think this because no matter how many times u spin the probability/likelihood stays the same
Alright, lets get started.
I hope, the dimensions of rectange are asked in this question.
Suppose the width of rectangle = x in
Given that length of the rectangle is 3 in longer than the width.
It means length of the rectangle = (x+3) in
Now, the area of the rectangle = lenght * width
area of the rectangle = 
area of the rectangle =
The area of a rectangle is 70 in square (given in question)
Equalling both areas
Subtracting 70 in both sides
Factoring
It will give two values of x
x = -10 (which is not possible because length could not be negative)
x = 7
Means width 
length 
Means the dimensions of rectangle are 7 in and 10 in. : Answer
Hope it will help :)
