Answer:
x = 6
Step-by-step explanation:
→ Rewrite equation
x + 3 = 9
→ Minus 3 from both sides
x = 6
Answer:
x = 5
Step-by-step explanation:
Given
2x - 2 + 5 = 13, that is
2x + 3 = 13 ( subtract 3 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Answer:
No, they are not scaled copy's.
Step-by-step explanation:
So we can flip figure F to where it is facing the direction that figure A is.
First we do 105 divided by 35, the corresponding sides, and get 3. If you do 96 divide by 19, you get 5.052631579. You are free to use my explanation word for word as your reason why.
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
Answer:
14 mi
Step-by-step explanation:
V = 718.38 mi³, r = 7 mi, find h
Use V = πr²h/3
718.38 = 3.14 * 7² * h/3
718.38 = 51.287 h
h = 718.38/51.287 = 14 mi
