Formula for Diameter: <span>2 x radius
Formula for Radius: R= C/2(pi)</span>
R= 176/2(22/7)
R=28.01
2(28.01)=56.02
Answer= 56.02
Answer:
(-2, 1)
Step-by-step explanation:
Systems of equations can be solved using different methods. For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable:
-3(-5x - 3y = 7) or 15x + 9y = -21
5(-3x - 4y = 2) or <u>-15x -20y = 10</u>
-11y = -11
y = 1
Solve for x: -5x - 3 = 7
Add 3 to both sides: -5x -3 + 3 = 7 + 3 or -5x = 10
Solve for x: x = -2
(-2, 1)
Answer:
10 degrees
Step-by-step explanation:
:) Thank you enjoy your day kind human :)
-4x + 7y = -8 . . . (1)
-5x + 6y = 1 . . . .(2)
(1) x 5 => -20x + 35y = -40 . . . (3)
(2) x 4 => -20x + 24y = 4 . . . . .(4)
(3) - (4) => 11y = -44 => y = -44/11 = -4
From (2), -5x + 6(-4) = 1 => -5x - 24 = 1 => -5x = 1 + 24 = 25 => x = 25/-5 = -5
Therefore, x = -5, y = -4
The answer is D. The action taken between each number is multiplying by 3. With this question, I'd say an easy way to answer it is to look at each answer given (in this case 36 and 108) and see if it fits the sequence with the given values (12 and 324).
