20 points!! What is the value of p? 10p+5= 18p–6/2 A–8 B–1/8 C4 D8
Artemon [7]

The answer is D.) 8

Explanation: 10p+5= 18p–6/2

Subtraction Property of equality states that you subtract the same number from both sides of an equation.

Subtract 10p from both sides of an equation

10p+5-10p = 18p-62-10p

Simplify:

5 = 8p -62  

Addition Property of equality states that you add the same number from both sides of an equation.

Add 62 to both sides of an equation:

5+62 = 8p -62 +62

Simplify:

67 = 8p        

Division Property of equality states that you divide the same number from both sides of an equation.

Divide by 8 in equation [3] ;

Simplify;

p = 8.375 ≈ 8 (approx)

Therefore, the value of p is, 8

Hope this helps :) sorry if wrong and sorry about confusion.

What’s 4 1/5 X 2 1/4
maxonik [38]

Answer:

9 9/20

Step-by-step explanation:

4 1/5 * 2 1/4

Change the mixed nubers to improper fractions

4 1/5 = (5*4+1)/5 = 21/5

2 1/4 = (4*2+1) /4 = 9/4

21/5 * 9/4 = 189/20

Now we change it back to a mixed number

20 goes into 189   9 times   (20*9 = 180  with 9 left over)

9 9/20

IceJOKER [234]
Given that the function

C(h)=\frac{2h^2+5h}{h^3+8}

models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue.

The number of hours it will take for the concentration of the injection to be less than 0.5% is given by:

0.5\ \textgreater \ \frac{2h^2+5h}{h^3+8} \\ \\ \Rightarrow0.5(h^3+8)\ \textgreater \ 2h^2+5h \\ \\ \Rightarrow h^3+8\ \textgreater \ 4h^2+10h \\ \\ \Rightarrow h^3-4h^2-10h+8\ \textgreater \ 0 \\ \\ \Rightarrow h\ \textgreater \ 5.54

Given that the first injection was given at 8:00 am, the time the next injection should be given is 2 pm.
