2(4x-1) + 3x = 8x - 2 + 3x
= 11x - 2
Hope this helps
So you would do 5*2x +5*-8 +15=-15
Then simplify so it would be 10x + -40 + 15 = -15
Then add -40 and 15 together
Then it would be 10x + -25 = -15
Then add 25 to -25 and -15
So it would be 10x = 10
And then divide 10 from 10 with would be 1 so x = 1
Answer:
0.32 mL
Step-by-step explanation:
d = m/v
v = m/d
v = 4.0 g ÷ 12.5 g/mL
g ÷ g cancels out the unit g
v = 0.32 mL
