6
Step-by-step explanation:
2x -4 = 8 , 8+4=12 , 12÷2=6
Answer:
$44.94
Step-by-step explanation:
400+100+100 = 600
22.40 + 10 +10 = 42.40
(22.40 for the first 400 and 10 for each additional 100)
If tax is 6%, you can multiply the whole thing (42.40) by 1.06 to get the total amount of 44.94.
Why 1.06? If you think about it, tax is 6%. 6% is the same as 0.06. You pay 100% for the products, so with tax, it's the equivalent of 106%, or 1.06.
Answer: 12 sqrt(5)
Explanation:
First simplify:
= Sqrt(45)
= sqrt(9*5) sqrt of 9 is 3 so bring out 3
= 3sqrt(5)
= 2sqrt(20)
= 2sqrt(4*5) sqrt of 4 is 2 so bring that out and multiply it by 2
= 4sqrt(5)
= 5 sqrt(5) is already simplified
= 3sqrt(5) + 4 sqrt(5) + 5sqrt(5)
= 12 sqrt(5)
I think the answer would be B
Answer:
A. y = 3x/4
Step-by-step explanation:
a proportional relationship between x and y is a straight line passing through the origin (0, 0).
The equation must be in the form y = kx.
y = 3x/4
y = 3/4x
