The answer is R=60... yu have to subtract 10r from both sides which then leaves you with -60=-1r. From that, you divide both sides by -1 which ends to giving your answer which is r=60

Answer:

r = 60

Step-by-step explanation:

With any equation with a variable, you want to isolate the variable to find its actual value. I'll show you a step by step:

10r - 60 = 9r

Subtract 9r from both sides:

10r - 9r - 60 = 9r - 9r

Simplify:

r - 60 = 0

Add 60 to both sides to isolate r:

r - 60 + 60 = 0 + 60

Simplify:

r = 60

Please help me! How do I find the area of the shaded region in the circles?
Alenkinab [10]

Answer:

ok, so i've never done this before, but i think i know how you do it. So first, find out the area of the whole triangle place in the circle shown on the diagram. Then, the area in the triangle that's not purple is what you need to subtract from the whole piece, i hope this helps

If (-2,3), 3x-2ky+4=0 find the value of k
ipn [44]
Answer: k = -1/3

Step-by-Step Explanation:

=> 3x - 2ky + 4 = 0
Value of ‘x’ = -2
Value of ‘y’ = 3

Substitute values of ‘x’ and ‘y’ :-
=> 3x - 2ky + 4 = 0
= 3(-2) - 2k(3) + 4 = 0
= -6 - 6k + 4 = 0
= -6k = 6 - 4
= -6k = 2
= k = 2/-6
=> k = -2/6 = -1/3

Therefore, k = -1/3

The coordinates of the midpoint of gh are m(-13/2,-6) and the coordinates of one endpoint are g(-4,1). what is the other endpoin
Alex777 [14]

Applying the midpoint formula, the coordinates of the other endpoint are: (-9, -13).

<h3>How to Apply the Midpoint Formula?</h3>

The midpoint formula, which can be used in determining the coordinates of the midpoint between two endpoints is usually expressed as: M[(x1 + x2)/2, (y1 + y2)/2].

Given the following coordinates:

Midpoint of GH --> m(-13/2,-6) = (x, y)

One endpoint ---> G(-4, 1) = (x1, y1)

The other endpoint ---> (x2, y2)

Plug in the values into the formula used in calculating the midpoint:

m(-13/2,-6) = [(-4 + x2)/2, (1 + y2)/2]

Solve for x2

-13/2 = (-4 + x2)/2

-13/2 × 2 = -4 + x2

-13 = -4 + x2

-13 + 4 = x2

-9 = x2

x2 = -9

Solve for y2

-6 = (1 + y2)/2

2(-6) = 1 + y2

-12 = 1 + y2

-12 - 1 = y2

-13 = y2

y2 = -13

Thus, using the midpoint formula, the coordinates of the other endpoint are: (-9, -13).
