If you would like to solve for x, you can do this using the following steps:
3x / 6 + 1 = 7
3x / 6 = 7 - 1
x/2 = 6 /*2
x = 6 * 2 = 12
The correct result would be x = 12.
Solve equation [1] for the variable x [1] x=(3y+6)
Plug this in or variable x in equation [2]
[2] 2(-3y+6)-y= 10
[2] -7y=-2
// solve equation [2] for the variable y
[2] 7y= 2
[2] y=2/7
By now we know this much
X= -3y+6
Y=2/7
Use the y value to solve for x
X=-3(2/7)+6=36/7
(x,y)=(36,7), (2/7)
1/5 of 20 is 4.
2/5 of 20 is 8.
Therefore, Ron used 8 apples to make his pies.
Answer:
-3 ≥ x ≥ 9
Step-by-step explanation:
The domain are the x-values of every point in your graph. Since it a continuous domain, it'll be represented with ≥. Your two extremities are -3 and 9. Therefore, your domain is -3 ≥ x ≥ 9.
A is 180 degrees, B is 180 degrees, C is definition of complementary angle, D is 180-angle 2, and E is angle 3.
