Answer:

3 (x+5) =6 (use the distributive property)

3x + 15 = 6  ( subtract 15 from both sides to isolate the x-term)

3x = -9 (divide both sides by 3 to get x alone)

x= -3 (the answer )

If angle w and angle v are supplementary angles and angle v=49, find angle w
Inessa05 [86]

Answer: 131°

Step-by-step explanation:

Supplementary angles are the angles that when we add them together, their sum is equal to 180°.

From the question, we are informed that angle w and angle v are supplementary angles and angle v=49.

V + W = 180°

49° + W= 180°

W = 180° - 49°

W = 131°

A party rental company has chair and tables for rent. The total cost to rent 6 chairs and 2 tables is $20. The total cost to ren
liubo4ka [24]
Based on the problem statement you can write two equations for the cost of tables (t) and chairs (c).
.. 6c +2t = 20
.. 3c +5t = 35

You can solve these by your favorite method to find the costs are
.. chairs cost $1.25
.. tables cost $6.25

_____
My favorite method is to use the graphing calculator at Desmos [dot] com. Many graphing calculators will solve equations like these either directly, graphically, or indirectly using matrix functions. If you want to solve them by "elimination," you can double the second equation and subtract the first to get
.. 8t = 50

A rectangle has a height of x+9 and a width of x^2+2x.
Irina-Kira [14]

Answer:

The area of the entire rectangle is given by: x^3 + 11x^2 + 18x

Step-by-step explanation:

The calculation of its area is straightforward, we only need to multiply its height times its width:

A = (x + 9)(x^2 + 2x)= x^3 + 2x^2 + 9x^2 +18x = x^3 + 11x^2 + 18x

Therefore the are are of the entire rectangle is given by: x^3 + 11x^2 + 18x
