Answer:
The price of the kilogram of cookies is $ 1.8
Step-by-step explanation:
Call x the price of the kilogram of candy and call y the price of kilogram of cookies
Then we know that
We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy
So
We solve this equation for x and then we substitute it in the first equation.
He had to pay back 1080 per year or 90 per month in total he had to pay $160 more dollars of interest then what he got
Answer:
y = 9 + 5/2x. this is in standard form (y = mx + b)
Answer: 8
Step-by-step explanation:
We can use trigonometry to solve this:
If we call the angle at the top Ф then x is the opposite and 8 is the adjacent
Therefore we use Tan to solve this:
Tan Ф = opposite/adjacent
Tan 45 = X/8
1 = X/8
8 x 1 = X
Therefore X = 8
