Hello!

First, let's write the problem.
3\left(x-2\right)+2\left(x+1\right)=-14
Apply the distributive property on the left side of the equation.
=3x-6+2x+2
Add like terms.
=5x-4
Let's plug that in into the original equation.
5x-4=-14
Add 4 to both sides.
5x-4+4=-14+4
5x=-10
Divide both sides by 5.
\frac{5x}{5}=\frac{-10}{5}

Our final answer would be,
x=-2

You can feel free to let me know if you have any questions regarding this!
Thanks!

The selling price of a refrigerator, is $739.20. If the mark up is 20% of the dealers cost , what is the dealers cost of the ref
Lisa [10]

Mark up percentages are used to increase the prices of items

The dealers cost of the refrigerator is $591.36

<h3>How to determine the dealer cost</h3>

Represent the dealer cost of the refrigerator with x.

Given that the markup is 20% and the selling price of the refrigerator is $739.20, then we have the following equation

x = 739.20 * (1 - 20%)

Evaluate the product

x = 591.36

Hence, the dealers cost of the refrigerator is $591.36

Papessa [141]

Answer:

23 days

Step-by-step explanation:

Given that the mass of a particular substance is known to grow exponentially at a rate of 1.5% per day

Initial mass = 230 gm

After t days, mass = 325 gm

The equation is

P(t) = 325 = 230 (1+\frac{1.5}{100} )^t\\\frac{325}{230} =1.015^t\\log 1.413 = t log 1.015\\t = \frac{log 1.413}{log 1.015} =\frac{0.1502}{0.0065} \\=23.229

Approximately after 23 days the mass will become 325 gms.

Find the length of the third side. If necessary, round to the nearest tenth. 10 14 ​
abruzzese [7]

Answer:

9.8 units

Explanation:

According to Pythagoras theorem, the square of length of the hypotenuse is equal to the sum of squares of lengths of other two sides.

Let the third side be x units.

Then,

x² + 10² = 14²

=> x² + 100 = 196

=> x² = 196 - 100

=> x² = 96

=> x = √96

=> x = 4√6

=> x = 9.79....

=> x = 9.8 (Rounding to the nearest tenths)

So, the length of the third side is 9.8 units.
