Answer:
x = -5
Step-by-step explanation:
-4(x+3)=8
(-4)(x)+(-4)(3)=8 (distribute)
-4x - 12 = 8
-4x - 12 + 12 = 8 + 12
-4x = 20
-4x/-4 = 20/-4 =
x = -5

Answer: The primary cause of low pH in precipitation over northeastern North America is sulphuric acid (H2SO4) from industrial and urban emissions of sulphur dioxide (SO2). Nitric acid (HNO3) generated from emissions of nitrogen oxides (NOx) is a significant contributing factor in this region.
Step-by-step explanation:
Answer:
first option
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin30° = , cos30° =
sin30° = = = ( cross- multiply )
2x = 32 ( divide both sides by 2 )
x = 16
----------------------------------------------------------
cos30° = = = ( cross- multiply )
2y = 32 ( divide both sides by 2 )
y = 16
