Answer:
1/4 x
Step-by-step explanation:
I think this because you don't know the amount of salt so that would be labeled x.
Answer:
72
Step-by-step explanation:
only 35 from A and 37 from B fit the range, so 35+37 is 72

Answer:
D
Step-by-step explanation:
To be an identity we require both sides of the equation to equate
A
8x + 9 ≠ 8x - 3 ← not an identity
B
7x - 2 = 8x + 4 - x = 7x + 4 ≠ 7x - 2 ← not an identity
C
11 - (2x + 3) = 11 - 2x - 3 = - 2x + 8 ≠ - 2x - 8 ← not an identity
D
5x + 8 - x = 6x - 2(x - 4), that is
4x + 8 = 6x - 2x + 8 = 4x + 8 ← both sides equate thus an identity
To figure this out, you'd use the a^2+b^2=c^2 formula. Since you have your two sides, you want to find the value for c. So, you'd plug in two for a and b.
2^2+2^2=c^2
4+4=c^2
Add up the two fours to get 8 and square root it, and you get 2.828427124...
Answer:
6 hours 15 minutes
Step-by-step explanation:
1 litre = 1000cm³
45 litres = 45000cm³
Volume = rate × time
45000 = 2 × t
t = 22500 secs
= 375 mins
