Answer:

x=12

Step-by-step explanation:

3(x-1)=2x+9       - Original equation

3x-3=2x+9        - Distribute 3 through the parentheses

3x-2x-3=9         - Move variable to the left-hand side and change sign

3x-2x=9+3        - Move constant to the right-hand side and change its sign

x=9+3               - Collect like terms and add

x=12                  - Answer

Hope this helps

5(8n+ 7) &lt; 5-5(n+3)
svet-max [94.6K]

Answer:

n<-1

Step-by-step explanation:

Distribute 5 and -5 into each parenthesis respectively: 40n+35<5-5n-15

Combine like terms: 40n+35<-5n-10

Add 5n to both sides: 45n+35<-10

Subtract 35 from both sides: 45n<-45

Divide both sides by 45: n<-1

Geomtry plz help 15 points
VladimirAG [237]

Answer:

m∠E=57°

Step-by-step explanation:

∠FDE=∠FED=(4x+1)° (base angles of isos triangle)

2(4x+1)+(5x-4)=180 (angle sum of triangle)

    8x+2+5x-4=180

             13x-2=180

                 13x=180+2

                       =182

                     x=182÷13

                       =14

Hence, m∠E = (4x+1)°

                     = [4(14)+1]°

                     = (56+1)°

                     = 57°
