Okay let’s go through this together I’ll break it down.
2x+3/ x-2 = 38/12
Cross multiply
12(2x+3) = 38(x-2)
24x+36 = 38x-76
- 36= -36
—————————-
24x= 38x-112
-38x= -38x
———————-
-14x = -112
—————— divided
-14x = -14
X= 8
There is a total of 0.00425 grams of iron in the liquid.
Answer:
C
Step-by-step explanation:
For the lines to be parallel, then the 2 given angles are alternate and congruent, thus
15x - 46 = 9x + 8 ( subtract 9x from both sides )
6x - 46 = 8 ( add 46 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9 → C
X-intercept is 8
Y-intercept is 3
