To find the answer:
4(x - 0.8) = 3.8x - 5.8 \\ 4x - 3.2 = 3.8x - 5.8 \\ 4x - 3.8x =  - 5.8 + 3.2 \\ 0.2x =  - 2.6 \\ x =   - \frac{ 2.6}{0.2}  \\ x =  - 13

Therefore, x=-13.

Hope it helps!

Answer:  The required solution is x = -13.

Step-by-step explanation: We are given to solve the following linear equation in variable x :

4(x-0.8)=3.8x-5.8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Solving equation (i) means finding the value of the unknown variable x.

The solution of equation (i) is as follows :

4(x-0.8)=3.8x-5.8\\\\\Rightarrow 4x-3.2=3.8x-5.8\\\\\Rightarrow 4x-3.8x=3.2-5.8\\\\\Rightarrow 0.2x=-2.6\\\\\Rightarrow x=-\dfrac{2.6}{0.2}\\\\\Rightarrow x=-13.

Thus, the required solution is x = -13.

Ber [7]

Answer:

15 more weeks

Step-by-step explanation:

425 - 125 (what shes already saved)

300 divided by 20 (amount shes saving each week)

Result is 15, so 15 more weeks.

Hope this helped :)

If you mean how many weeks total, 125 according to the 20 dollars a week would bring it 22 weeks i think.. since the answer answer is 21.2 weeks exactly when you divide 425 by 20.

zhuklara [117]

Answer:

The surface area of door is 33 680 cm².

Step-by-step explanation:

Given that the surface area of a cuboid which is the 3D of rectangle is :

s.a = 2(l \times w) + 2(l \times h) + 2(w \times h)

let \: l = 80 \\ let \: w = 3 \\ let \: h = 200

s.a = 2(80 \times 3) + 2(80 \times 200) + 2(3 \times 200)

s.a = 2(240) + 2(16000) + 2(600)

s.a = 480 + 32000 + 1200

s.a = 33680 \:  {cm}^{2}
