Answer:
After 8 months of internet use both the connection will cost the same.
Step-by-step explanation:
Fast Internet charges $40 for installation and $52.45 per month.
So, the total cost after using x months of the internet in Fast Internet will be
C = 40 + 52.45x
Quick Internet has free installation but charges $57.45 per month.
So, the total cost after using x months of the internet in Quick Internet will be
C = 57.45x
Now, if those two cost are same then
40 + 52.45x = 57.45x
⇒ 5x = 40
⇒ x = 8
Therefore, after 8 months of internet use both the connection will cost the same. (Answer)
The right fraction represents the percentage; 42 over 100 (100 is the total), or 0.42.
The left fraction is the part number over the whole number. The whole number is unknown, so we use 'x'.
Your answer is 75.
Answer:
There are 8 more girls
Step-by-step explanation:
If you divide 32 by 8 (since the ratio is 3:5 which is 8 parts (3+5)). You get 4.
Thus, there are 12 boys and 20 because 3*4 is 12 and 5*4 is 20. 12+20 is 32.
Just divide the percentage by the amount they are asking
Answer:
y + 30 = 4/5(x - 10)
Step-by-step explanation:
Given the slope, 4/5, and point (10, -30):
We can plug these values into the point-slope form:
y - y1 = m(x - x1)
Let (x1, y1) = (10, -30)
and m = 4/5
y - (-30) = 4/5(x - 10)
y + 30 = 4/5(x - 10)
Therefore, the point-slope form is y + 30 = 4/5(x - 10)
