Plug 50 into y and find x.
5x + 10 (50) = 800
5x + 500 = 800
5x = 800 - 500
5x = 300
x = 300 ÷ 5
x = 60
Heres the formula and steps
The six is in the hundredths place so we will out the fraction as “over a hundred”, meaning 16/100. But this can be simplified to 4/25 :)
So 4/25 is your answer
Answer:
The equivalent ratios are:
s = \frac{LA}{r}s=
r
LA
r = \frac{LA}{s}r=
s
LA
The formula LA = rsLA=rs is given
In order to determine the equivalent ratios, make r the subject of the formula and s the subject of the formula in the above equation
To make s, the subject of the equation, divide both sides of the equation by r
s = \frac{LA}{r}s=
r
LA
To make r, the subject of the equation, divide both sides of the equation by s
r = \frac{LA}{s}r=
s
LA

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
