Answer:

Y=0.2

X=0.9

Step-by-step explanation:

-6x+5y=1

+6x -> 5y=1 -> y=0.2

6x+4y=-10

+6x -> 12x+4y=-10

12x+4*0.2=-10

12x+0.8=-10

-0.8

12x=-10.8

x=0.9

Find the radius and diameter of a circular puddle whose

o-na [289]

Answer:

$r = 35cm$

Step-by-step explanation:

Given

$C = 220cm$

$\pi = \frac{22}{7}$

Required

Determine the radius

Circumference (C) is calculated as:

$C = 2\pi r$

Where r represents radius

Substitute values for C and $\pi$

$220cm = 2 * \frac{22}{7} * r$

$220cm = \frac{44}{7} * r$

Multiply through by 7/44

$\frac{7}{44} * 220cm = \frac{7}{44} * \frac{44}{7} * r$

$r = \frac{7}{44} * 220cm =$

$r = \frac{7 * 220cm }{44} =$

$r = \frac{1540\ cm}{44}$

$r = 35cm$

Hence, the radius is 35cm

Endpoint (-10,9); midpoint (2,5)

Sergeu [11.5K]

x₂ + x₁ = m y₂ + y₁ = m
 2 2

-10 = x₂
9 = y₂

2=m
5=m

Plug in given numbers

-10 + x = 2 9 + y = 5
2 2
Solve

-10 + x = 2*2
2 *2

-10 + x = 4
+10 +10
x = 14
(9 + y)/2(2) = 5 (2)
9 + y = 10
-9 -9
y=1

Final Answer: (14,1)
