Answer:
Both are linear
Step-by-step explanation:
As long as the equation can be written in y = mx + b form, then it is linear.
Answer:
I think it's either 10√3 or 10
Answer:
16
Step-by-step explanation:
3/4 = 12/x
Since 3 × 4 = 12
[Apply the same number with the numerator and denominator]
4 × 4 = 16
x = 16
7 % of cost price is 2.80 , What about 1%?
7 = 2.80
1 = x (where x is the price value of 1% in dollars)
We simplify the above equation, so:
7 × x = 2.8 × 1 → 7x = 2.8 → x = 2.8 / 7 → x = 0.4 dollars
We know that 100% represents the whole price,
so if 1% is 0.4 dollars, then 100% will be 0.4 × 100 = 40 dollars
Therefore the store charged $40 dollars for the helmet before tax
