Answer:

a) 9a + 6b

b) 5c - 3d

Step-by-step explanation:

4a + 7b + 5a - b =

= 4a + 5a + 7b - 1b

= 9a + 6b

6c + 4d - c - 7d =

= 6c - 1c + 4d - 7d

= 5c - 3d

Formula for pressure and volume

Alecsey [184]

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.

The dimensions of an ancient Egyptian rug are 6 feet by 8 feet. Priscilla is creating a drawing of the rug with the scale 4 cm =

Taya2010 [7]

Answer:

12 x 18 CM.

Step-by-step explanation:

Because 3 cm is 1 ft so if it is 4 you multiply that by 3 which equals 12 , and for 6 feet you multiply that by 3 cm and get 18. SO it is 12 x 18 cm.

a plane flies 5.0km due north from a point O and then 6.0km on a bearing of 060° the pilot then changes course on a bearing of 1

Virty [35]

The plane flies a distance of approximately 10.536 kilometers in straight line and with a bearing of approximately 035°.

A plane that travels a distance $r$ , in kilometers, with a bearing of $\theta$ sexagesimal degrees can be represented in standard position by means of the following expression:

$\vec r = r\cdot (\sin\theta, \cos \theta)$ (1)

We can obtain the resulting vector ( $\vec R$ ) by the principle of superposition:

$\vec R = \Sigma_{i=1}^{n} [r_{i}\cdot (\sin \theta_{i}, \cos \theta_{i})]$ (2)

If we know that $r_{1} = 5\,km$ , $\theta_{1} = 0^{\circ}$ , $r_{2} = 6\,km$ , $\theta_{2} = 60^{\circ}$ , $r_{3} = 4\,km$ and $\theta_{3} = 120^{\circ}$ , then the resulting vector is:
