Answer:
GIVE ME MY RAMEN
Step-by-step explanation:
3.
add like terms
30 + 7k = 100
100-30 = 70
70 divided by 7k = 10
k = 10
4. add the z's together
2z - 6 -2 = -10
+ 6 + 2
-10 will be -2 now since we dragged the -6 and -2 to the other side
2z = -2
z = -1
5. 3.2x - 1.7x = 1.5x
1.5x + 5.5 = 10
10 would be 4.5 since we dragged 5.5 to the other side so it would be 10 - 5.5
3.2x = 5.5
x = 1.71875
6.
3/4x - 1/4x = 2/4x
14 - 3 = 11
2/4x = 11
x = 22
Answer:
x = -20

Answer:
314 cm²
Step-by-step explanation:
It's not the point O, but the circle O, a point has no area.
The area of a circle is given by the formula A = π r²
We don't have r (radius), but we have the diameter, which is double the radius. So, r = d / 2 = 20 cm / 2 = 10 cm
Now, we can plug r directly into the equation:
A = π r² = π 10² = 100π = 314 cm²

<h3>Given </h3>
- JM = 27, ML = 16, JL = 46, NK = 15, m∠KLM = 48°, m∠JKM = 78°, and m∠MJL = 22°
<h3>To find</h3>
<h3>Solution</h3>
<u>JKLM is a parallelogram and therefore has equal opposite angles:</u>
- ∠JKL = ∠JML and ∠KJM = ∠KLM
<u>Sum of all four is 360°:</u>
- 2m∠JKL + 2m∠KLM = 360°
- m∠JKL + m∠KLM = 180°
- m∠JKL + 48° = 180°
- m∠JKL = 180° - 48°
- m ∠JKL = 132°
