Answer:

x = -12

Step-by-step explanation:

y = 2/3x - 3

-11 = 2/3x - 3

-11 + 3 = 2/3x

-8 = 2/3x

-8 ÷ 2/3 = x

-12 = x

SOLUTION

Consider the property, opposite angle of a cyclic quadrilateral are supplementary

hence

$\angle NMP+\angle NOP=180^0$

Recall that

$\begin{gathered} \angle NMP=\angle M=(8x-24)^0 \\ \text{and } \\ \angle NOP=\angle O=(4x)^0 \end{gathered}$

Hnece, we have that

$\begin{gathered} \angle M+\angle O=180^0(opposite\text{ angles of a cyclic quadrilateral)} \\ (8x-24)^0+4x^0=180^0 \end{gathered}$

Then

$\begin{gathered} 8x-24+4x=180 \\ 8x+4x-24=180 \\ 12x-24=180 \\ \text{Add 24 t o both sides } \\ 12x-24+24=180+24 \\ 12x=204 \\ \text{divide both sides by 12} \\ \frac{12x}{12}=\frac{204}{12} \\ \text{Then} \\ x=17 \end{gathered}$

Hence

x=17

Since

$\begin{gathered} \angle NOP=(4x)^0 \\ \text{substitute the value of x, we have } \\ \angle NOP=4\times17=68^0 \\ \text{Hence } \\ \angle NOP=68^0 \end{gathered}$

Therefore

The measure of angle NOP is 68⁰

Answer; 68⁰ (The fourth Option )

Kevin is solving this problem. 737 × 205 What are the partial products Kevin will need to solve the problem? A. 3,685 and 147,40

Andrew [12]

the answer is A

700 x 5 = 3500

30 x 5 = 150

7 x 5 = 35

3500 + 150 +35 = 3685

700 x 200 = 140,000

30 x 200 = 6000

7 x 200 = 1400

140000 + 6000 + 1400 = 147400

1: Almost all rocks are made of minerals but, different rocks have different kinds of minerals.
2: Sedimentary, metamorphic, and igneous.
3: Weathering is breaking down of the rocks, soil, and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and water.
4: i don't know this one sorry :(
5: Metamorphic Rocks
6: Geological Society
7: Igneous Rocks. They are about 3ft long!
8: Foliated Metamorphic Rocks
9:Phaneritic Igneous Rock
I hoped this helped! :) sorry for not knowing number 4 :( Have a good day! :)
