Step-by-step explanation:
1 2/6 = 6/6 + 2/6
answer is A.
----------------------
5/8 - 4/8 = 1/8
answer is B 1/8 lb
---------------------------
1 6/8 = 14/8
1 3/8 = 11/8
14/8 + 11/8 = 25/8 = 3 1/8
answer is C. 3 1/8 miles
-----------------------
1 7/100 + 4 6/10 = 5 67/100 (5 and 67/100)
------------------------------------
3/4(4) =3
1/4(2) = 1/2
3 - 1/2 = 6/2 - 1/2 = 5/2 = 10/4
answer is C. 10/4 ft
Answer:
A=2(wl+hl+hw)
Step-by-step explanation:
Answer:
The constant of proportionality is 2.
Step-by-step explanation:
In an equation for which we are looking for the constant of proportionality, we use the base form below.
y = kx
In which k is the constant of proportionality. If we use the equation given
y = 2x
We can see k = 2

Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B
