Mathematics

Answer:

Step 1: Simplify both sides of the equation.

0= 8− $\frac{2x}{5}$

0 = 8 + $\frac{-2}{5}x$

0 = $\frac{-2}{5}x+8$

Step 2: Flip the equation.

$\frac{-2}{5} x + 8=0$

Step 3: Subtract 8 from both sides.

$\frac{-2}{5} x+8-8=0-8$

$\frac{-2}{5} x=-8$

Step 4: Multiply both sides by 5/(-2).

$(\frac{5}{-2} ) *( \frac{-2}{5} x) = (\frac{5}{-2} )*(-8)$

<h2>Therefor, the answer is x=20</h2><h2 />

-2(2x - { }) + 1 = 17 - 4x<br><br> For what missing value is the equation an identity?

leva [86]

<span>When we put 8 in the bracket we can get the answer as 17 - 4x i.e Consider the LHS -2 ( 2x - 8) + 1 = -2 (2x-8) + 1 = -4x+16+1 = -4x + 17 = 17-4x = RHS LHS = RHS Proved</span>

A room has dimensions 6.8m x 9.2m. Steven wants to paint the walls of the room. A large tin of paint covers 20m^2 and cost £11.7

Dmitry_Shevchenko [17]

Answer:

Total cost to paint the room = £73.51

Step-by-step explanation:

Given:

Dimensions of the room = 6.8 m $\times$ 9.2 m

Cost of tin of paint = £11.75

A tin of paint covers an area = 20 $m^2$

To find the cost of painting the room with two coats of paint.

Solution:

Area of the room = $length\times width=6.8\ m\times 9.2\ m= 62.56\ m^2$

We will use unitary method to find the amount of paint required for the room.

If $20\ m^2$ of area is covered by 1 tin of paint.

For $1\ m^2$ of area, amount of paint required = $\frac{1}{20}$ of a tin

Then, for $62.56\ m^2$ amount of paint required = $\frac{62.56}{20}=3.128$ tins of paint.

<em>For double coats twice paint must be required.</em>

So, total amount of paint required for painting the room with two coats of paint = $3.128\times 2=6.256$ tins of paints.

Using unitary method to find total cost.

If 1 tin of paint costs = £11.75

<em>6.256 tins of paint will cost = $6.256\times \£11.75=\£73.508\approx\£73.51$ </em>

Total cost to paint the room = £73.51
