How to do: 4(x+7)=2(x+7)

Mathematics

In this question, you're solving for x.

Solve for x:

4(x+7) = 2(x+7)

<em>use distributive property</em>

4x + 28 = 2x + 14

<em>subtract 2x from both sides</em>

2x + 28 = 14

<em>subtract 28 from both sides</em>

2x = -14

<em>divide both sides by 2</em>

x = -7

4(x+7) becomes 4x+28 you multipli the 4 in parentheses ans 2(x+7) becomes 2x+14

4x+28=2x+14 you move the x termes to the left and other numbers to the right look:

4x-2x=14-28 when you change the sides always change the sign +or-
2x=-14
2x/2=-14/2
X=-7

Si se invierten $ 500 a una tasa de 5% anual. Hallar el valor futuro a 3 años si el interés es compuesto trimestralmente.
9966 [12]

Answer:

the future value is $5800.38

Step-by-step explanation:

Given that

The invested amount i.e present value is $500

The rate is 5 % per year so quarterly rate is 5% ÷ 4 = 1.25%

The time period is 3 per year so for quartely it is 3 × 4 = 12

We need to find out the future value

So as we know that

Future value = Present value × (1 + rate of interest)^time

= $500 × (1 + 0.0125)^12

= $580.38

hence, the future value is $5800.38

How would you solve cos(5x)=sin(10x) ?
Tomtit [17]
We will use double angle identities:
cos (5x ) = sin (10x )   
cos (5x ) = 2 cos (5x ) sin ( 5x )
cos ( 5 x) - 2 cos ( 5 x ) sin ( 5x ) = 0
cos ( 5 x ) · [ 1 - 2 sin (5 x) ] = 0
cos ( 5 x ) = 0                    or :       1 - 2 sin (5 x) = 0
5 x = π/2 +kπ,  k∈Z                        sin (5 x) = 1/2
x1 = π/10 + kπ/5                           5 x = π/6+2kπ    , k∈ Z
                                                       5 x = 5π/6 +2kπ , k∈ Z
                                                       x 2 = π/30 +2kπ/5
                                                       x 3 = π/9  + 2kπ/5

Airida [17]

Answer:

\frac{z+11y}{5}

Step-by-step explanation:

z=5x-11y

+11y on both sides

z+11y=x

divide by 5 on both sides

Answer: 0.8 or 80% (either way is correct)

Explanations 80/100 equals 80 divided by 100 which equals 0.8 ; 0.8 equals 80%

(Hope this helps!)
