Answer:

p=7

Step-by-step explanation:

4p+5=33

33-5=28

4p=28

28/4=7

p=7

4(7)+5=33

Answer:

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

4p - 28 = 4 • (p - 7)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : 4 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : p-7 = 0

Add 7 to both sides of the equation :

p = 7

5(2/5) how to solve it?

mina [271]

Answer:

Step-by-step explanation:

Solve. Technically, there are two methods. You can first multiply, or first divide.

Essentially the question is:

(5 * 2)/5

2 * (5/5)

Solve. Remember to follow PEMDAS. First solve the parenthesis, then simplify:

(5 * 2)/5 = (10)/5 = 2

2 * (5/5) = 2 * 1 = 2

2 is your answer.

This is my next Trigonometry question I am needed help on- I just want to be sure I've got it right, or if not, then the steps I

$\bf \textit{simmetry identities}\\\\
sin(-\theta)=-sin(\theta)\\\\
-------------------------------\\\\
sin(-\theta)=\cfrac{1}{5}\implies -sin(\theta)=\cfrac{1}{5}\implies sin(\theta)=\cfrac{-1}{5}\cfrac{\leftarrow opposite=b}{\leftarrow hypotenuse=c}
\\\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\implies \pm\sqrt{5^2-(-1)^2}=a
\\\\\\
\pm\sqrt{24}=a\implies \pm2\sqrt{6}=a$

so. hmm which is it? the +/- ? well, neverminding for a second, the value of tangent, just looking at the sign, the tangent is positive,

tangent = opposite/adjacent.... so that only happens, when both are the same sign, + or - both

now, we know the sine is -1/5.. if the sine is negative, the cosine also has t to be negative, so we'd use the -2√(6) = a

thus $\bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies cos(\theta)=\cfrac{-2\sqrt{6}}{5}$
