Can you help me? <br><br> 4+3(x+5)=5x-7

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

4 + 3(x + 5)=5 x - 7

3x + 19=5x - 7

3x + 19 - 19=5x - 7 - 19

3x =5x - 26

3x - 5x=5x - 26 - 5x

-2= -26

-2x/-2 = -26/-2

x= 13

It might be wrong. I may have made a mistake with typing sorry.

Hope this helps a bit.

You are rolling two dice at the same time. What is the probability of rolling a sum of 5 or 9?

baherus [9]

You can get a 5 by rolling :
1 and 4
2 and 3
3 and 2
4 and 1

You can get a 9 by rolling :
3 and 6
4 and 5
5 and 4
6 and 3

There are 36 possible outcomes, hence your probability is $\frac{4\cdot2}{36}=\boxed{\frac29}$

Which are the solutions of x2 = 19x + 1?

Finger [1]

Answer:

$(\frac{19-\sqrt{365}} {2},\frac{19+\sqrt{365}} {2})$

Step-by-step explanation:

we have

$x^2=19x+1$

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-x^{2}-19x-1=0$

$a=1\\b=-19\\c=-1$

substitute in the formula

$x=\frac{-(-19)\pm\sqrt{-19^{2}-4(1)(-1)}} {2(1)}$

$x=\frac{19\pm\sqrt{365}} {2}$

$x=\frac{19+\sqrt{365}} {2}$

$x=\frac{19-\sqrt{365}} {2}$

$(\frac{19-\sqrt{365}} {2},\frac{19+\sqrt{365}} {2})$

therefore

StartFraction 19 minus StartRoot 365 EndRoot Over 2 EndFraction comma StartFraction 19 + StartRoot 365 EndRoot Over 2 EndFraction
