Answer:
y=4x-1
Step-by-step explanation:
5 : 7 = 5x : 7x
Sum of a pair <span>of consecutive angles of a parallelogram = 180⁰.
5x+7x=180
12x = 180
x= 15
5x=15*5 = 75⁰
7x=15*7 = 105⁰
Two angles are 75⁰ each,
and 2 angles 105⁰ each.
Check:
Sum of angles in the </span><span>parallelogram is 360⁰.
</span><span>75*2 + 105*2 = 360
360 = 360 True

Answer: C(t) = 0.4t + 4
Step-by-step explanation:
Let t represent the total number of minutes of using a computer at the internet cafe.
The cafe charges an initial fee to use the computer and then an additional price per minute of usage. The initial charge to use the computers is $4 and the total charge would be $6 for 5 minutes of use. This is expressed as
5t + 4 = 6
5t = 6 - 4 = 2
t = 2/5 = 0.4
It means that the charge per minute would be $0.4
Therefore, the equation for the function C(t), representing the total cost of using a computer for t minutes at the internet cafe is
C(t) = 0.4t + 4
