Answer:
x = (-1)/23
Step-by-step explanation:
Solve for x:
-3 x - 4 (x - 1) = 5 (2 x + 1) + 6 x
-4 (x - 1) = 4 - 4 x:
4 - 4 x - 3 x = 5 (2 x + 1) + 6 x
Grouping like terms, -3 x - 4 x + 4 = 4 + (-3 x - 4 x):
4 + (-3 x - 4 x) = 5 (2 x + 1) + 6 x
-3 x - 4 x = -7 x:
-7 x + 4 = 5 (2 x + 1) + 6 x
5 (2 x + 1) = 10 x + 5:
4 - 7 x = 10 x + 5 + 6 x
Grouping like terms, 10 x + 6 x + 5 = (10 x + 6 x) + 5:
4 - 7 x = (10 x + 6 x) + 5
10 x + 6 x = 16 x:
4 - 7 x = 16 x + 5
Subtract 16 x from both sides:
4 + (-7 x - 16 x) = (16 x - 16 x) + 5
-7 x - 16 x = -23 x:
-23 x + 4 = (16 x - 16 x) + 5
16 x - 16 x = 0:
4 - 23 x = 5
Subtract 4 from both sides:
(4 - 4) - 23 x = 5 - 4
4 - 4 = 0:
-23 x = 5 - 4
5 - 4 = 1:
-23 x = 1
Divide both sides by -23:
Answer: x = (-1)/23

Step-by-step explanation: Right on edg.
Answer:
y=1/3x + 2
Step-by-step explanation:
Since slope intercept form is y=, I first added x to each side to get x on the other side. Then I divided each side by 3 to get y, and ended up with y=1/3x+2 as my answer.

Answer:
53/72
Step-by-step explanation:
5/8 = x - 1/9
+1/9 +1/9
5/8 + 1/9 = x
9(5/8) + 8(1/9)
45/72 + 8/72
x= 53/72
First you substitute in the values so you have
V^2=(64)20
then you just simplify it
V^2=1280
V=the square root of 1280
V= about 35.7770876
or
V=the square root of 256 times <span>the square root of 5
V=16 times </span><span>the square root of 5
also V would typically be called velocity. it's very similar to speed but it is just easier to remember because it starts with a V</span>
