Answer:
![x = 1/2y + 3/4x - m](https://tex.z-dn.net/?f=x%20%3D%201%2F2y%20%2B%203%2F4x%20-%20m)
Step-by-step explanation:
<u>Step 1: Distribute
</u>
<u />![4(x + m) = 2y + 3x](https://tex.z-dn.net/?f=4%28x%20%2B%20m%29%20%3D%202y%20%2B%203x)
![4x + 4m = 2y + 3x](https://tex.z-dn.net/?f=4x%20%2B%204m%20%3D%202y%20%2B%203x)
<u>Step 2: Subtract 4m from both sides
</u>
<u />![4x + 4m - 4m = 2y + 3x - 4m](https://tex.z-dn.net/?f=4x%20%2B%204m%20-%204m%20%3D%202y%20%2B%203x%20-%204m)
![4x = 2y + 3x - 4m](https://tex.z-dn.net/?f=4x%20%3D%202y%20%2B%203x%20-%204m)
<u>Step 3: Divide both sides by 4
</u>
<u />![4x / 4 = (2y + 3x - 4m) / 4](https://tex.z-dn.net/?f=4x%20%2F%204%20%3D%20%282y%20%2B%203x%20-%204m%29%20%2F%204)
![x = 1/2y + 3/4x - m](https://tex.z-dn.net/?f=x%20%3D%201%2F2y%20%2B%203%2F4x%20-%20m)
Answer: ![x = 1/2y + 3/4x - m](https://tex.z-dn.net/?f=x%20%3D%201%2F2y%20%2B%203%2F4x%20-%20m)
Answer:
1/2, 7/11, 3/4
Step-by-step explanation:
Answer:
32
Step-by-step explanation:
you have to find how many min in a hour so 20 divided by 5 is 4 then 4x8 is 32
Answer:
6 = −4x + y
−5x − y = 21
Answer: (-3, -6)
2x + y = 20 6x – 5y = 12
Answer:
(7 , 6)
Step-by-step explanation:
Solve the system of equations by substitution.
6 = −4x + y --> y = 4x + 6
−5x − y = 21
Substitute y = 4x + 6 into −5x − y = 21
−5x − (4x + 6) = 21
-5x - 4x - 6 = 21
-9x = 27
x = - 3
y = 4(-3) + 6
y = -12 + 6
y = -6
(-3, -6)
Solve the system by the elimination method.
2x + y = 20
multiply the equation by (-3) ; 2x + y = 20 so
-6x - 3y = - 60
6x – 5y = 12
------------------add
-8y = - 48
y = 6
2x + y = 20
2x + 6 = 20
2x = 14
x = 7
(7 , 6)
Answer:
(x-4)*2 + (y-2)*2 = 25
Step-by-step explanation:
(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
h = 4
k = 2
r = 5
sub in all this info:
(x-4)*2 + (y-2)*2 = 25
