Congruence Properties
In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!
The Reflexive Property of Congruence
The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.
G:$2.99
R:$16.99
For every 1R we have 3G.
1R+3G=$16.99+3($2.99)
So 1R+3G=$25.96
If we take $129.80÷$25.96, we get 5.
So let's try 5.
5R+15G=5($16.99)+15($2.99)
So 5R+15G=$129.80

Answer:
Step-by-step explanation:
Given expression is 
Let us perform the operations inside the parentheses first.
Answer:
The missing exponent = power of 3
852.763 x 10³ = 852763
Step-by-step explanation:
The expression 852.763 x 10?
A number that is 1,000 times the value of 852.763 is calculated as:
852.763 × 1000 = 852763
Converting this to exponent
852.763 × 10³ = 852763
Therefore, the missing exponent that would result in number that is 1,000 times the value of 852.763 is power of 3 meaning 10³
