A) 3x + 4 = 5x - 10. It's easy to identify the lines' equations by their y-intercept and slope.
We can start by solving for 10-5a+(18-b). By plugging in a and b, we get
10 - 10 + (18 - 11)= 7
28 ÷ (a × 2) = 28/4 = 7
20 + b − (4 × a) = 31 - 8 = 23
49 − 43 + (a ÷ a) = 49 - 43 + 1 = 7
30 − 25 + (b − 9) = 5 + 2 = 7
50 ÷ a − (b + 20) = 25 - 31 = -6
So, 28 ÷ (a × 2), 49 − 43 + (a ÷ a), and 30 − 25 + (b − 9) will all have the same answer as 10−5a+(18−b)
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.

Do 40divided by two then divide 5 by 2
From the equation of (y+5)^2=12(x+2), Focus is the distance(a) from the vertex(h,k).The equation is written in standard form, where 4a=12, solving for a
4a=12
a=3
The focus of the flashlight is found in 4th quadrant at the coordinates(1,-5).
