Answer

X=4 or X= - 10

Step one divide both sides by -4

-4(|x+3|) over -4 = -28 over -4

|x+3|=7

We know either

X+3=7 or x+3=-7

X+3=7 (possibility 1)

X+3-3= -7 - 3 (subtract three from both sides)

X=-10

Answer

X=4 or X=-10 both are the correct answer it could go either way

White and black shapes are used in a game Some of the shapes are circles All the other shapes are squares The ratio of white to

PIT_PIT [208]

Answer:

The fraction of all shapes which are square in shape is $\frac{23}{32}$ .

Step-by-step explanation:

Given that , in a game , white and black shapes are used. Some of them are circle in shape and remains are square in shape.

The ratio of white to black shapes are 5:11.

Consider 5x= the number of shapes which are white in color.

11x= The number of shapes which are black in color.

There are (5x+11x)= 16x shapes in the game.

The white circle and white square are in the ratio 3:7.

The number of white square is

$=(\textrm{The number of white shape})\times (\frac{7}{3+7})$

$=(5x)\times (\frac{7}{10})$

$=\frac{7x}{2}$

The black circles and black square are in the ratio 3:8

The number of black square is

$=(\textrm{The number of black shape})\times (\frac{8}{3+8})$

$=(11x)\times (\frac{8}{11})$

=8x

Therefore the total number of shape which are square is

$=\frac{7x}{2}+8x$

$=\frac{7x+16x}{2}$

$=\frac{23x}{2}$

The fraction of all shape are square is

$=\frac{\textrm{shape in square}}{\textrm{Total number shape}}$

$=\frac{\frac{23x}{2}}{16x}$

$=\frac{23}{32}$

Oliga [24]

15\x and 80\100
15 times 100=1500
1500=8x
then you divide 1500 by 80 so x is by itself
x=18.75

kramer

Answer:

Step-by-step explanation:

Use PEDMAS. So first addition has to be done as it is inside parenthesis. After that multiplication has to be done

0.060 +

In decimal multiplication, first multiply the numbers ie, 2 * 68 which is 136. Then count the number of decimal places in both the multiplicands and keep the same number of decimal places in the result(136).

0.02 * 0.068 = 0.00136
