First change the 0.05 to a fraction.
0.05 = 1/20
Then you have the equation:
10/20 = 0.5

Answer:

0.05= \frac{0.5}{10}

Step-by-step explanation:

In this question we have given an equation

0.05*10 = 0.5..............(1)

we have to rewrite this equation as a division equation

we can rewrite this equation as division equation in two ways

First form

devise the equation (1) by 0.05

we got

10= \frac{0.5}{0.05}

second form

divide equation (1) by 10 we got

0.05= \frac{0.5}{10}

SOLVE FOR X??? <br><br><img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B3%7D%20%2B2%20%3D%5Cfrac%7Bx%7D%7B4%7D%2B3" id="TexFor

Answer:

\boxed{ \bold{ \boxed{ \sf{1. \:  \:  \:  \:  \: x = 12}}}}

\boxed{ \bold{ \boxed{ \sf{2. \:  \:  \:  \:  \: x = 3}}}}

Step-by-step explanation:

\sf{1. \:  \:  \:  \:  \frac{x}{3}  + 2 =  \frac{x}{4}  + 3}

Move x / 4 to left hand side and change its sign

Similarly, move 2 to right hand side and change it's sign

\longrightarrow{ \sf{ \frac{x}{3}  -  \frac{x}{4}  = 3 - 2}}

Take the L.C.M of 3 and 4

L.C.M of 3 and 4 = 12

\longrightarrow{ \sf{ \frac{x \times 4 - x \times 3}{12}  = 3 - 2}}

\longrightarrow{ \sf{ \frac{4x - 3x}{12}  = 3 - 2}}

\longrightarrow{ \sf{ \frac{x}{12}  = 3 - 2}}

Subtract 2 from 3

\longrightarrow{ \sf{ \frac{x}{12}  = 1}}

Do cross multiplication

\longrightarrow{ \sf{x  = 1 \times 12}}

\longrightarrow { \sf{x = 12}}

--------------------------------------------------------------------

\sf{2. \:  \:  \:  \: 3(4 + 2x) = 33 - x }

Distribute 3 through the parentheses

\longrightarrow{ \sf{12 + 6x = 33 - x}}

Move x to left hand side and change it's sign

Similarly, move 12 to right hand side and change it's sign

\longrightarrow{ \sf{6x +  x = 33 - 12}}

Collect like terms

\longrightarrow{ \sf{7x = 33 - 12}}

Subtract 12 from 33

\longrightarrow{ \sf{7x = 21}}

Divide both sides by 7

\longrightarrow{ \sf{ \frac{7x}{7}  =  \frac{21}{7} }}

Calculate

\longrightarrow{ \sf{x = 3}}

Hope I helped!

Best regards! :D

(Figure is provided below)
DanielleElmas [232]

Answer:

The measure of ∠z   = 137°

Step-by-step explanation:

Here, angle 1  = 43°

To find : ∠z

Straight line Angle:  The angle which measures exactly 180° and is extended by a point on a straight line is called straight angle.

According to the given figure:

  ∠1 + ∠z  = 180 °  (STRAIGHT LINE ANGLE)

or,   ∠z  = 180 ° - 43° = 137°

Hence, the measure of ∠z   = 137°.
