Answer: n=0.4 or 2/5
Step-by-step explanation:
We have to make 2 equations
A = Adults C= Children
So: A + C = 1300
15A + 10C = 17250
We can solve for A and C in 2 ways, SUBSTITUTION or ELIMINATION
I'll do substitution
SUBSTITUTION: Subtract A from both sides
A + C = 1300
-A -A
C = 1300 - A
Plug C is to the 2nd equation
15A + 10(1300 - A) = 17,250
15A + 13,000 - 10A = 17,250
5A + 13,000 = 17,250
- 13,000 -13,000
5A = 4250
---- ---------
5 5
A= 850
So, there are 850 adults, subtract 850 from 1,300 and there 450 children
Answer: 850 adults
450 children
The answer this is the 3rd option choice: Reaches a maximum height of 549 feet after 5.75 seconds.
Answer:
3w+7=31
Step-by-step explanation:
Subtract 7 on both sides
3w+7=31
-7 -7
Divide by 3 on both sides
3w=24
/3 /3
w=8
Hopefully, this helps! :)
Answer:
11.) y-int:(0,1); x-int:(1,0)
12.) y-int:(0,8); x-int:(4,0)
13.) y-int:(0,-9); x-int:(-3,0)
14.) y-int:(0,-5); x-int:(-2.5,0)
Step-by-step explanation:
For each equation, first you have to graph it. Then to find the y-intercept, you mark and check where your line of your equation intersects the y-axis. To find the x-intercept, you mark and check where the line of your equation intersects the x-axis. The y-intercept always will have the coordinates of x=0 and the x-intercept always will have the coordinates of y=0.
