Answer:

x = 40

Step-by-step explanation:

5= 1/5x -3

Add 3 to each side

5+3= 1/5x -3+3

8 = 1/5x

Multiply by 5 to isolate x

5*8 = 1/5x *5

40 =x

Hello! :)

Answer:

$\boxed{x=40}$

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

First, you switch sides of an equation.

$\frac{1}{5}x-3=5$

Then, you add by 3 from both sides of an equation.

$\frac{1}{5}x-3+3=5+3$

Add by the number from left/right.

$5+3=8$

$\frac{1}{5}x=8$

Multiply by 5 both sides.

$5*\frac{1}{5}x=8*5$

Multiply by the numbers.

8*5=40

x=40

Hope this helps!

Leona [35]

Option B. is true.

A isn't true because 0.9919 is lesser than 0.999.
C is false because 2.6953 is lesser than 2.75. They are not equal.
D is also false because 4.9395 is not greater than 5.0.

Answer:

B. 1.4359 < 1.446

Hope you could get an idea from here.

Triangle ABC has vertices A( -3, 5) B ( 6, 9) and C ( -4, - 12) in the coordinate plane. The triangle is reflected over the x- a

hichkok12 [17]

Answer:

The coordinates of triangle A"B"C" will become

A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )

Step-by-step explanation:

Original vertices of triangle ABC are ;

A ( -3, 5 ) B( 6, 9 ) C ( -4, -12 )

after reflection over x-axis

A( -3,-5 ) B( 6, -9 ) C( -4,12 )

when the triangle is rotated

x coordinates becomes -y while y coordinates becomes x

The coordinates of triangle A"B"C" will become

A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )

If the length of a rectangle is increased by 120%, and its width is decreased by 20%, what is the percentage change in the area

velikii [3]

Answer:

The area of the rectangle is increased in 76 percent.

Step-by-step explanation:

The area of a rectangle ( $A$ ) is represented by the following formula:

$A = w\cdot l$

Where:

$w$ - Width.

$l$ - Length.

If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: ( $l = 2.2\cdot l_{o}$ , $w = 0.8\cdot w_{o}$ )

$A = (2.2\cdot l_{o})\cdot (0.8\cdot w_{o})$

$A = (2.2)\cdot (0.8)\cdot w_{o}\cdot l_{o}$

$A = 1.76\cdot A_{o}$

The area of the rectangle is increased in 76 percent.
