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

angle EPF = angle DPG

=> 4x + 48deg = 7x

=> 3x = 48 deg

=> x = 16

=> angle EPF = 4(16) +48 = 112deg

Three workers can load a truck in 8 minutes. How many workers need to join this team so that they can load that truck in 6 minut

slamgirl [31]

Answer:

1 extra worker

Step-by-step explanation:

If three workers load the truck in 8 minutes we have that:

3 workers = 8 minutes

We know that if we wanted to reduce the time at, for example, half, we would need to increase the workers in a half. More generally, if we want to reduce the time in 1/X me need to multiply the workers by X.

Here me need to reduce the time in 6/8 as 8*6/8 = 6. So, we will need:

3*8/6 = 24/6 = 4 workers.

So, we will need 1 more worker as we already have 3.
