A 14 foot is cut into two pieces so that one piece is 3 feet longer than twice the shorter piece
DochEvi [55]
To answer the question above, let x be the shorter one of the pieces. With the variable, we can express the longer piece as 2x + 3. Based on the given, the sum of the lengths of these pieces should sum up to 14 ft. 

                                        2x + 3 + x = 14 ft, x = 3 2/3 ft

Substituting this value for the longer piece, we get 10 1/3 ft. Thus, the lengths of the pieces are 3 2/3 ft and 10 1/3 ft.

Four points are always coplanar if they: Check all that apply. A. lie on the same line. B. lie on different planes. C. lie on di
kotykmax [81]
<span>D. lie in the same plane.
</span><span>
The definition of capillarity is that points are considered as co-planar when these points are on the same plane, so it is obvious that the answer D is true because this statement is the definition of capillarity. This is shown in Figure 1.

</span><span>A. lie on the same line.
</span><span>
If four points lie on the same line then there will be a plane that contains this line, therefore the definition is fulfilled. This is shown in Figure 2.

</span><em>Finally, the correct answers are A. and D.</em>

List three ways o express 3 to the 5 power as a product of powers
tia_tia [17]
3 ways to express 3 to the 5th power as the product of powers First expression => 3 x 3 x 3 x 3 x 3 - In this expression, we multiplied 3 5 times and the product is 243 Second expression => 3 ^ 5, in where ^ read as raised to the power, the product is also 243 Third expression => 3^2 x 3^3 => (3 x 3) x (3 x 3 x 3) => 9 x 27, the product also equals to 243.

Solve the following system of equations by substation.
Cerrena [4.2K]

Answer:

C. (-1, 3)

Step-by-step explanation:

Label the 2 equations:

5y= 7x +22 -----(1)

x= -6y +17 -----(2)

Substitute (2) into (1):

5y= 7(-6y +17) +22

5y= -42y +119 +22 <em>(</em><em>Expand</em><em> </em><em>bracket</em><em>)</em>

5y= -42y +141 <em>(</em><em>Simplify</em><em>)</em>

42y +5y= 141 <em>(</em><em>+</em><em>42y</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

47y= 141

y= 141 ÷47 <em>(</em><em>÷</em><em>4</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

y= 3

Substitute y= 3 into (2):

x= -6(3) +17

x= -18 +17

x= -1

Thus, the solution is (-1, 3).
