Answer:

x = -13

Step-by-step explanation:

6(4x + 50) = 3(x+8) + 3

24x + 300 = 3x + 24 + 3

21x + 300 = 27

21x = -273

x = -13

{20 points}

Olegator [25]

Midpoint formula is ( (x₁+x₂) / 2, (y₁+y₂) / 2 )

So that would be ( (9-1) / 2, (8-2) / 2 ) = ( 8 / 2, 6 / 2 ) = (4, 3)

Final answer: (4, 3)

Answer:

SSS

∆PQR = 43

Step-by-step explanation:

The postulate to solve ∆PQR ≅ ∆STU is SSS. Both of the triangles have all three sides given, which means it can be solved for congruence.

9 + 6y + 5 + 14 = 9 + 8y +14

28 + 6y = 9 + 8y + 14

28 + 6y = 8y + 23

-6y -6y

--------------------------

28 = 2y + 23

-23 -23

---------------------

5 = 2y

---- ----

2 2

2.5 = y

9 + 14 + 6(2.5) + 5

23 + 15 + 5

23 + 20

∆PQR = 43

Ariele is hiking down into the canyon. She starts at the rim and hikes down 55 feet in 234 minutes. If she continues at this rat

Aleksandr-060686 [28]

Answer:

This means that she will be 16.35 ft away from the rim in 15 minutes at this current rate.

Step-by-step explanation:

What we are asked here is imply to state how long in terms of distance would be Arielle position after 15 minutes

Now, 55 ft will take her 234 minutes

x ft will take her 15 minutes

x * 234 = 55 * 15

234x = 3825

x = 3825/234

x = 16.35 ft

This means that she will be 16.35 ft away from the rim in 15 minutes at this current rate.

Area of circle 1 = πr²
Area of circle 1 = π (10)²
Area of circle 1 = 100π km²

Area of circle 2 = πr²
Area of circle 2 = π (5)²
Area of circle 2 = 25π km²

Number of times the bigger circle is greater than the smaller circle
$\dfrac{100 \pi }{25 \pi } = 4$

------------------------------------------------------------------------------------
Answer: The big circle is 4 times greater than the small circle.
