1/3(a + b) = 60
a + b = 60 * 3 = 180

1/4(a - b) = 28
a - b = 28 * 4 = 112

a + b = 180
a - b = 112
---------------add
2a = 292
a = 292/2
a = 146

a + b = 180
146 + b = 180
b = 180 - 146
b = 34

so ur 2 angles are : 146 and 34

Combine like terms.<br> - 2x - 14 = -3.- 1
UNO [17]

Answer:

combine -3-1

- 2x - 14 =  - 4

if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.

- 2x - 14 =  - 4 \\    \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  + 14 \:  \:  + 14

your equation there will be

- 2x = 10

then you will divide -2 on both sides

\frac{ - 2x}{ - 2}  =  \frac{10}{ - 2}

finally x will equal

x =  - 5

PLEASE HELP I NEED IT TO PASS THIS CLASS
andreyandreev [35.5K]

Answer:

Angle 5 = 37°

Angle 8 = 143°

Step-by-step explanation:

Angle 2 = Angle 8

Reason : Alternate exterior angles are equal.

Therefore,

Angle 8 = 143°

Angle 5 + Angle 8 = 180°

Reason : Angle 5 & 8 are in a linear pair.

Angle 5 + 143° = 180°

Angle 5 = ( 180 - 143 )°

Angle 5 = 37°
