Answer: 873
Step-by-step explanation:
let age = x
x/3 - 76 = 215
x/3 = 291
x = 873
first, distribute -6 to (2b + 1), giving you -12b - 6, and then on the another side of the equation, distribute -2 to (5 + 4b) giving you, -10 - 8b. now we need to put our coefficients on one side so we will add 8b to each side of the equation, giving us -6 = -10 - 8b + 12b, then we will add 10 to both sides of the equation giving us, 10 -6 = -8b +12b, this gives u 4 = 4b. then, you would solve for b, which equals 1.
Answer:
A
Step-by-step explanation:
We are starting with 51
50x10=50
1x1=1
since there were 0.21 seconds, we first have to find the tenths place.
0.1x2=0.2
now that we found the tenths place, we need to find the hundredths place
0.01x1=1
FINAL ANSWER
(5 x 10) + (1 x 1) + (2 x 0.1) + (1 x 0.01)
Answer:
pH = 3.3
Step-by-step explanation:
pH is given by the formula; pH = –log[H+]
The concentration of hydrogen ions is 5.0 × 10–4 moles per liter.
Therefore;
pH = - log₁₀(5.0 × 10^–4)
= -( - 3.301)
= 3.301
Thus;
The approximate pH will be; 3.3
