So, the equation is

(5+2a)+a=29

5+3a=29

Can someone give me the steps to solving this?

DerKrebs [107]

Answer:

$\tan \theta = \dfrac{8}{15}$

Step by step explanation:

$\text{Given that,}\\\\~~~~~~~\sin \theta = \dfrac{8}{17}\\\\\implies \sin^2 \theta = \dfrac{64}{289}\\\\\implies 1-\cos^2 \theta = \dfrac{64}{289}\\\\\implies \cos^2 \theta = 1-\dfrac{64}{289}\\\\\implies \cos^2 \theta = \dfrac{225}{289}\\\\\implies \cos \theta =\pm\sqrt{\dfrac{225}{289}}\\\\\implies \cos \theta = \pm\dfrac{15}{17}$

$\text{In quadrant I, all ratios are positive, so,}~ \cos \theta = \dfrac{15}{17}\\\\\text{Now,}\\\\\tan \theta = \dfrac{\sin \theta }{\cos \theta}\\\\\\~~~~~~~~=\dfrac{\tfrac{8}{17}}{\tfrac{15}{17}}\\\\\\~~~~~~~~=\dfrac{8}{17} \times \dfrac{17}{15}\\\\\\~~~~~~~=\dfrac{8}{15}$

Joan gets $1,000 paycheck each month. She saves $50 from each paycheck. What percent of her paycheck does Joan save?

kirill [66]

Answer:

The percentage of paycheck Joan saves is 5% .

Step-by-step explanation:

Given as :

The paycheck that Joan gets each months = x = $1,000

The money that Joan saves from each paycheck = y = $50

Let The percentage of paycheck Joan saves = z%

Now, According to question

The percentage of paycheck Joan saves = $\dfrac{\textrm money that Joan saves from each paycheck}{\textrm total paycheck money}$ × 100

Or, z = $\dfrac{y}{x}$ × 100

Or, z = $\dfrac{50}{1000}$ × 100

Or, z = 5%

So, The percentage of paycheck Joan saves = z = 5%

Hence,The percentage of paycheck Joan saves is 5% . Answer

Solve the system using any method. y = 3x + 2 y = 7x - 10

Marysya12 [62]

Answer:

x=3

y=11

Step-by-step explanation:

y = 3x + 2 equation 1

y = 7x - 10 equation 2

using equation 1 in equation 2 we have:

3x + 2 = 7x - 10

2=7x - 3x -10

2 = 4x -10

2+10 = 4x

12= 4x

12/4 = x

we have:

x= 3

using equation 1:

y = 3x + 2

y= 3(3)+2

y=9+2

y=11
