-5x - 3(-4x - 9) = 83
Add 5x to both sides
-3(-4x-9) = 83 + 5x
Divide by -3
-4x-9 = 83/3 + 5/3x
Subtract 5/3x
-4x -5/3x -9 = 83/3
Add 9
-17/3x = 110/3
Multiply by 3
-17x = 110
Divide by -17
X = 6 and 8/17

-5x-3(-4x -9)= 83

Distribute. 

-5x+12x+27= 83 (two negatives equal a positive) 

Combine like terms.

7x+27= 83

Subtract 27 from both sides.

7x= 56

Divide 7 into both sides.

x=8

I hope this helps!

The Perimeter of a rectangle is 36. If there's 5n + 3 and 1/4n + 2, what's the value of n?
seropon [69]
Perimeter: 36

5n + 3 = 36
5 · 6.6 + 3 = 36

N = 6.6
------------------------------------------
Perimeter: 36

1/4n + 2 = 36
1/4 · 136 + 2 = 36

N = 136

Hopefully i understood the question correctly :) Hope this helps

Unit 1 geometry basics quiz 1-3 angle measures and relationships
ASHA 777 [7]

Answer/Step-by-step explanation:

1. Side CD and side DG meet at endpoint D to form <4. Therefore, the sides of <4 are:

Side CD and side DG.

2. Vertex of <2 is the endpoint at which two sides meet to form <2.

Vertex of <2 is D.

3. Another name for <3 is <EDG

4. <5 is less than 90°. Therefore, <5 can be classified as an acute angle.

5. <CDE is less than 180° but greater than 90°. Therefore, <CDE is classified as an obtuse angle.

6. m<5 = 42°

m<1 = 117°

m<CDF = ?

m<5 + m<1 = m<CDF (angle addition postulate)

42° + 117° = m<CDF (Substitution)

159° = m<CDF

m<CDF = 159°

7. m<3 = 73°

m<FDE = ?

m<FDG = right angle = 90°

m<3 + m<FDE = m<FDG (Angle addition postulate)

73° + m<FDE = 90° (Substitution)

73° + m<FDE - 73° = 90° - 73°

m<FDE = 17°
