Step-by-step explanation:

y = x - 6...(1) \\  3x - 2y = 8...(2) \\ substituting \: y = x - 6 \: in \: equation \: (2) \\ 3x - 2(x - 6) = 8 \\  3x - 2x + 12 = 8 \\ x = 8 - 12 \\ x =  - 4 \\  \implies \: y = x - 6 =  - 4 - 6 =  - 10 \\  \therefore \: y =  - 10 \\ \therefore \:  \{x, \:  \: y \} =  \{ - 4, \:  \:  - 10 \}

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>

ZP bisects ∠OZQ so that ∠OZP = 8x – 9 and ∠PZQ = 5x + 18. Find the value of x, and the measure of each angle. You must show all
Assoli18 [71]
<span>x = 9 Since ZP bisects â OZQ, that means that the measurements for â OZP and â PZQ are the same. So create an equation with their respective values set to each other. 8x - 9 = 5x + 18 Now solve for x 8x - 9 = 5x + 18 Subtract 5x from both sides 3x - 9 = 18 Add 9 to both sides 3x = 27 Divide both sides by 3 x = 9</span>

September 6 is a Read Book Day.Polina read 5 times as many pages as Marcus read.Together,the read 108 pages.How many pages did e
Gemiola [76]

Answer:

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Step-by-step explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

5y+y=108\\6y=108\\y=18

Find the value of x

x=5y -----> x=5(18)=90

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
