x = 15
if zabc = 130º
zabc = (6x+40)° = 130º
this equation can be rearranged to solve for x by isolating it (moving everything over to the other side).
(6x+40)° = 130º
solve it without the degrees sign because it looks confusing.
6x+40 = 130
6x+40 - 40 = 130 - 40 (subtract 40 from both sides)
6x = 90
6x/6 = 90/6 (divide both sides by 6)
x = 15
therefore x is 15. the degrees symbol is already included outside the bracket.
d. the population of california was approximately two times the population of florida.
california's population was 4 x 10^7= 40,000,000
florida's population was 2 x 10^7= 20,000,000
so therefore califirnia's population was approximately two times the population of florida.
i hope this
the volume of the sun is approximately one thousand times the volume of jupiter.
the value of x.
