N= -14
Step-by-step explanation:
first you add 16 to both sides, then -30 + -16 = -14
Step-by-step explanation:
six people because it has six seats
Answer:
52 units
Step-by-step explanation:
We know that,
<em>A perpendicular bisector cuts a line segment into two equal parts at 90°.</em>
As, CB is a perpendicular bisector of AD. So, it cuts AD into 2 equal parts.
We have,
AB = DB
i.e. 7x + 10 = 9x - 2
i.e. 7x - 9x = -2 - 10
i.e. -2x = -12
i.e. x = 6.
Thus, AB = 7x + 10 = 7×6 + 10 = 42 + 10 = 52.
Hence, the length of AB is 52 units.
Multiplied by 10 more each time
Answer:
y = 15 + 0.10x
y = 10 + 0.12x
Step-by-step explanation:
We'll use variable "x" to represent our minutes.
Frank's payment will always $15 no matter what, so there can't be a variable on it. Same with Josie & the $10.
For every minute, x, Frank pays an additional 10 cents with the $15.
For every minute, x, Josie will pay an additional 12 cents with the $10.
Because both equations equal y, we can set them equal to each other to find what value of x that their phone bills will be equal.
15 + 0.10x = 10 + 0.12x
5 = 0.02x
x = 250 minutes
Hope this helps. :)
