What is the x in this equation <br><br> 14x−8=4

Aleksandr-060686 [28]

Answer:

x = 6 / 7

Step-by-step explanation:

Let's solve your equation step-by-step.

14 x − 8 = 4

Step 1: Add 8 to both sides.

14x − 8 + 8 = 4 + 8

14x = 12

Step 2: Divide both sides by 14.

14 x / 14 = 12 / 14

x = 6 / 7

Hope it helps

The length of a rectangle is one foot more than twice its width if the area of the rectangle is 300 ft^2 find the dimensions of

umka21 [38]

Let's say the length is L, and the width is W
L is one foot more than 2W, so L=1+2W
the area of the rectangle: A=L*W=300
replace L with 1+2W: (1+2W)*W=300 =>2W^2+W-300=0
solve the quadratic equation: (W-12)(2W+25)=0
W=12 or W=-12.5 (impossible)
so the width is 12, and the length is L=1+2*12=25

please refer to this website for how to factor a quadratic equation

Mona wants to buy carpet for a floor in her house. The floor is rectangular with a width of 5 m and a length of 8 m. Two shops s

pshichka [43]

Answer:

Mona will save a total of $7 by going to Carpet World.

Step-by-step explanation:

First, we need to calculate the total area of the floor by multiplying the width by the length...

5m * 8m = 40m

Now we calculate the amount that it would cost to buy the carpet from each of the establishments. For the first establishment, we can buy 16 $m^{2}$ and get the next 8 $m^{2}$ half off and that would leave another 16 $m^{2}$ at full price. The second establishment we have a 5% off (0.95 of official price) for every 8 $m^{2}$ , since out total area is 5 times this amount then our total will have a 5% off.

Establishment 1: (16 $m^{2}$ * 2.20) + (8 $m^{2}$ * 1.10) + (16 $m^{2}$ * 2.20) = $79.20

Establishment 2: (40 $m^{2}$ * 1.90) * 0.95 = $72.20

Difference: 79.20 - 72.20 = $7

Mona will save a total of $7 by going to Carpet World.

Answer correctly please

Paul [167]

Answer:

$\$272,49$

Step-by-step explanation:

7. $\displaystyle /text{The answer makes sense because since the depreciation rate is 15%, we know that we need to use the "exponential decay" formula.}$

6. $\displaystyle /text{After a depreciation rate of 15% for the past 8 years, the stock is now worth approximately $272,49.}$

5. $\displaystyle 1000[0,85]^8 = 272,490525 ≈ \$272,49$

4. $\displaystyle 1000 = a \\ -15\% + 100\% = 1 - r; 85\% = 1 - r \\ 8\:years = time\:[t]$

3. $\displaystyle /text{We need to use the "Exponential Decay" formula} - f(t) = a[1 - r]^t, where a > 0$

2. $\displaystyle /text{How much is the stock worth after a depreciation rate of 15% per year?}$

1. $\displaystyle /text{initial amount: $1000, a depreciation rate of 15%, and a time period of 8 years}$

I am joyous to assist you anytime.
