Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3
You need to find the mass and the volume first to be able to figure out the density
Answer:
add all given angle
sum of all angles is equal to 180 degree
2t + j = 80
3(0.5)t + 2(0.5)j = 70
j = 80 - 2t
1.5t + j = 70
1.5t + 80 - 2t = 70
-0.5t = 70 - 80
-0.5t = -10
t = -10/-0.5
t = 20
j = 80 - 2t
j = 80 - 2(20)
j = 80 - 40
j = 40
so ur answer is C
