What is 2\3y plus y minus 4 equals 31

steposvetlana [31]

2/3 y+y-4=31

Simplify both sides of the equation

2/3 y-4=31

Combine like terms

(2/3 y+y)+(-4)=31

5/3 y-4=31

Add 4 to both sides

5/3 y-4+4=31+4

5/3 y=35

Multiply both sides 3/5

(3/5)*(5/3 y)=(3/5)*35

y=21

I hope that's help !

8. Solve the following triangle for all missing sides and angles.

vova2212 [387]

Answer:

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : $\frac{sin 42}{a} = \frac{sin 55}{175}$ ⇔ $a = sin42 \frac{175}{sin 55}$ ⇔ a= 142.95

Parte3 :

Using the same law : $c = sin 83\frac{a}{sin 42}$ or $c= sin 83\frac{175}{sin 55}$ ⇔ c= 212.04
