5. -[-2(x-4) - |1-3|] = -2x18

irina [24]

Solving the expression $-[-2(x-4) - |1-3|] = -2x18$ we get value of x: $x=\frac{3}{19}$

Step-by-step explanation:

We need to solve the equation $-[-2(x-4) - |1-3|] = -2x18$ and find value of x

Solving:

$-[-2(x-4) - |1-3|] = -2x18$

Multiply -2 with terms inside the bracket

$-[-2x+8 - |1-3|] = -2x18$

Solving |1-3| we get |-2|=2

$-[-2x+8 - 2] = -2x18$

$-[-2x+6] = -2x18$

Multiply (-) sign with terms inside the bracket

$+2x-6 = -2x18$

Multiply 2x with 18

$2x-6 = -36x$

Add 36x on both sdides

$2x-6+36x =0$

$38x-6 =0$

Add 6 on both sides:

$38x =6$

Divide both sides by 38

$x=\frac{6}{38}$

Simplifying:

$x=\frac{3}{19}$

So, Solving the expression $-[-2(x-4) - |1-3|] = -2x18$ we get value of x: $x=\frac{3}{19}$

The probability of three independent events happening one after the other is the multiplication of the probability of the single events.

The probability of spinning an odd number is 5/10=1/2, because there are 5 odd numbers (1,3,5,7 and 9) out of the 10 numbers from 1 to 10.

The probability of spinning a number less than 4 is 3/10, because there are 3 numbers (1,2 and 3) that are less than 4 out of the 10 numbers from 1 to 10.

The probability of spinning a 7 is 1/10, because you only have one good outcome out of 10.

So, the probability of winning the game is

$\dfrac{1}{2}\times\dfrac{3}{10}\times\dfrac{1}{10} = \dfrac{3}{200}$

1.4 – 5.5 – 1.73 + 1.8 – 1.09 –5.12 –8.72 5.12 –1.66

Novay_Z [31]

We'll do two by two,
1.4 – 5.5= -4.1
– 1.73 + 1.8= 0.07
Leaving – 1.09,

You get 
=-4.1+ 0.07- 1.09
=-4.03-1.09
=-5.12

Show your work 2x+y=-4;5x+3y=-6

miss Akunina [59]

Answer:

x = -6

y = 8

Step-by-step explanation:

Using substitution method.

2x + y = -4 -----------(I)

y = - 4 - 2x -----------(II)

5x + 3y = -6 -------------------(III)

Substitute y = -4 -2x in equation (III)

5x + 3(-4-2x) = - 6

5x - 12 - 6x = -6

5x - 6x - 12 = -6

Combine like terms

-x - 12 = -6 {Add 12 to both sides}

-x = -6 + 12

-x = 6 {Multiply by (-1)}

x = -6

Substitute x = -6 in equation (II)

y = - 4 - 2*(-6)

= -4 + 12

y = 8
