What is the value of n in the equation - {(2n + 4) + 6 = -9 +4(2n + 1)

Mathematics

Olenka [21]3 years ago

Answer:

n = 2.5 or n = (5/2)

Step-by-step explanation:

(2n+4) +6 = -9 + 4(2n+1)

first distribute the 4 to the (2n+1)

(2n+4) +6 = -9 + (8n+4)

then add 9 to both sides to cancel out the -9 on the right side

(2n+4) +15 = (8n+4)

next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract

15 = 6n

then divide 15 by 6 to get your final answer

n = 2.5

or

n = (5/2)

Well, we know that the total amount is $420, so we can already set one side of the equation. =420. Also, it said that the $420 is (equal to) 7/6b (b for balance).
Now just put it together!  7/6b=420 is your answer.

Answer:

x=14 , y = 21

Step-by-step explanation:

y=x-7...............1

5x+2y=7......2

reset eqn .....2

2y=-5x+7

so; y=-x-7 ×5

2y=-5x+7 ×1

5y = -5x -35

2y = -5x +7

5y-2y = -5 + 5 -35-7

<u>3y</u> = - <u>42</u>

3 3

y = 14

sub y=14 into eqn ...........1

y = -x -7

14 = - x -7

14 +7 = - x

-21 = x

x = 14 , y =-21

GIVING BRAINLIEST TO CORRECT ANSWER What rotation about the origin is equivalent to R-200°
TiliK225 [7]

The rotation about the origin that is equivalent to R-200° is; C. R160

<h3>How to find the angle of rotation?</h3>

We are given;

Origin = -200°

Now, even if we add and also subtract a complete rotation of 360° (or even several rotations of 360°), we will want to have the similar rotation.

Thus;

By adding 360° to -200°, we have;

α = -200° + 360°

α = 160°
