Step-by-step explanation:
66 1/2= 5ft. and 6 1/2in.
Answer:
Step-by-step explanation:
(1) 2x - 6y = -12
(2) x + 2y = 14
There is a -6y and a +2y. Since they have opposite signs, I'll try to eliminate the y terms. (That's my choice. There is more than one way to solve these.)
Multiply eq. (2) by 3:
3x + 6y = 42
Then add the result to eq. (1) to eliminate the y terms:
2x - 6y = -12
3x + 6y = 42
------------------
5x = 30, so x = 6
Now plug the value of x into eq. (2) and solve for y:
6 + 2y = 14
2y = 8
y = 4
Why did I use eq. (2) to solve for y? Because it's less work. I could have used eq. (1) instead:
2(6) - 6y = -12
12 - 6y = -12
-6y = -24
y = 4
More than one way to solve.
Answer:
I sure hope none is an answer because none of these work!
Step-by-step explanation:
C = 59 (F - 32)
(C/59) = F - 32
F = C/59 + 32
So no :(
m = x + y + z3
y = m - x - z3
So no :((
s = r^2 - 1
r = sqrt(s+1)
So no :000
A = 12(a+b)
A = 12a + 12b
12b = A - 12a
b = A/12 - a
So no :00(((
m = x + y^2
y = sqrt (m-x)
AND no :|
