Be careful you don't add unlike terms together (e.g. x^2 and x cannot be added or subtracted together).
<span>Be careful you don't mistake the 2 in x^2 as another number. Same for x^3, x^4. etc.</span>

Plz help

$x2y + z = 9 \\ \\ 1. \: x + 2y + z + - 2y = 9 + - 2y \\ x + z = - 2y + 9 \\ 2. \: x + z + - z = - 2y + 9 + - z \\ x = - 2y - z + 9 \\ \\ \\ x + y - z = 5 \\ \\ 1. \: x + y - z + - y = 5 + - y \\ x - z = - y + 5 \\ 2. \: x - z + z = - y + 5 + z \\ x = - y + z + 5 \\ \\ \\ 3x - y + 2z = 12 \\ 1. \: 3x - y + 2z + y = 12 + y \\ 3x + 2z = y + 12 \\ 2. \: 3x = y - 2z + 12 \\ 3. \: \frac{3x}{3} = \frac{y - 2z + 12}{3} \\ x = \frac{1}{3} y + \frac{ - 2}{3} z + 4$

If two fair dice are rolled at the same time, what is the probability that of it obtaining two multiples of 3?

Romashka-Z-Leto [24]

Im assuming this is a non biased 6 sided dice,

multiples of 3 would be 3 and 6 therefore chance of rolling one would be 2/6 = 1/3.

however since the question says two dice at the same time, you have to multiply the probability which would be 1/3 x 1/3 = 1/9

Find the volume of both shapes please answer will give brainiest Also please answer neatly.

SSSSS [86.1K]

Answer:

2). Volume = 14400 feet³

3). Volume = 157.5 ft³

Step-by-step explanation:

Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.

2). In this part of the question solid given is in the shape of an rectangular pyramid.

Volume of this oblique pyramid = $\frac{1}{3}(\text{Base})(\text{Height})$

Here 'B' = area of the base

h = height of the pyramid

Volume = $\frac{1}{3}(25\times 36)\times 48$

= 14400 cubic feet

4). Volume of a triangular cone = (Area of the triangular base)×(height)

= $[\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}$

= $\frac{1}{2}(7\times 9)\times {5}$

= 157.5 ft³
