Answer:
<em>4.9 - 4n</em>
Step-by-step explanation:
Given the expression;
2.4 - 5.5 -4n + 8?
Collect like terms;
2.4 - 5.5 -4n + 8?
2.4 - 5.5 + 8-4n
-3.1 + 8 - 4n
<em>4.9 - 4n</em>
<em></em>
<em>Hence the simplified form of the equation is 4.9 - 4n</em>
Though these segments aren't marked congruent in the diagram, the two lines inside the circle making up the bases of the triangles are congruent as all radii are congruent. So the triangles are congruent by SAS.
Answer:
8 and 10
Step-by-step explanation:
Set the first number as x, the second as y
x+y=18
2x-y=6
This is an binary system of first order equations
3x=24
x=8
y=10
Answer:

Step-by-step explanation:
To rid the denominators, multiply both sides by
.
We get:

Simplifying, we have:

Solving, we get:

Therefore, the solution with the greatest value is 
Answer:
x =27
Step-by-step explanation:
3x - 4y=65
lets substitute the value of y in the equation:
3x -4(4) =65
3x = 65 +16
3x= 81
x= 81/3
x = 27
