Step-by-step explanation:
All we have to do is see how many time 6³/₄ ft. can fit in 60³/₄ ft. through division.
60 ³/₄ ÷ 6 ³/₄ =
²⁴³/₄ ÷ ²⁷/₄ =
²⁴³/₄ × ⁴/₂₇ =

Answer:
(t, u, w) = (1, -2, -2)
Step-by-step explanation:
A graphing calculator makes short work of this, giving the solution as ...
(t, u, w) = (1, -2, -2)
__
There are many ways to solve this "by hand." Here's one of them.
Add the first and third equations. Their sum is ...
-3t +4w = -11 . . . . . [eq4]
Add this to twice the second equation. That sum is ...
(-3t +4w) +2(-4t -2w) = (-11) +2(0)
-11t = -11
t = 1
Substituting this into the second equation gives ...
-4(1) -2w = 0
w +2 = 0 . . . . divide by -2
w = -2 . . . . add -2
Substituting for t in the third equation lets us find u.
2(1) -2u = 6
-1 +u = -3 . . . . . divide by -2
u = -2 . . . . add 1
The solution is (t, u, w) = (1, -2, -2).
Answer: 7
Step-by-step explanation:
They are alternate interior angle
2x + 5 = 3x -2
2x = 3x -7
-x = -7
x = 7
