The given statement "A theorem is a statement that can be easily proved using a corollary" is false.

Answer: False

<u>Step-by-step explanation:</u>

A statement that would be proven on the basis of postulates and before proven theorem is called Theorems. "Corollary", a theorem that should come from a previous theorems (part of another statement). Contrary to the definitions, this may be reversible or irreversible if they are presented in the form "if - then."

Example for theorem: The measured angles of a triangle added to 180 degree.

The theoretical aspects of geometry consists of definitions, theorems, and postulates. Basically, these are elements of geometric proof.

How are the solutions to the inequality -2x ≥ 10 different from the solutions to -2x > 10?

CaHeK987 [17]

Answer:

First lets find the solutions to each inequality.

-2x $\geq \\$ 10 and -2x>10 (divide both sides by -2 to solve)

x $\leq$ -5 and x<-5

x $\leq$ -5 tell us that x could be -5 or less.

x<-5 tells us that x could be -6 or less.

The first one is less than or equal to which tells you that there is a possibility that the number is shows is could be an answer

Hope this helps ;)

Deangelo has $7 worth of dimes and quarters in a jar. He has 7 more quarters than dimes.

svlad2 [7]

D=number of dimes
q=number of quarters

let's count everything in cents
dimes are worth 10 cents
quarters are worth 25 cents

10d+25q=700
divide both sides by 5
2d+5q=140

he has 7 more quarters than dimes
q=7+d
subsitute 7+d for q in other equation

2d+5q=140
2d+5(7+d)=140
2d+35+5d=140
7d+35=140
minus 35 both sides
7d=105
divide both sides by 7
d=15

sub back

q=7+d
q=7+15
q=22

22 quarters and 15 dimes
