Answer:
475 students, 125 adults
Step-by-step explanation:
x + y= 600......equation 1
5x +9y= 3500.......equation 2
From equation 1
x +y = 600
x= 600-y
Substitute 600-y for x in equation 2
5(600-y) +9y= 3500
3000-5y+9y= 3500
3000+4y= 3500
4y= 3500-3000
4y= 500
y= 500/4
y= 125
Substitute 125 for y in equation 1
x + y= 600
x + 125= 600
x = 600-125
x= 475
Hence there are 475 students and 125 adults
Answer:
Step-by-step explanation:
1) the temperature rise, because 8.5 is C higher than 0 C
2) 8.5 - 0 = 8.5
So it rised by 8.5 degrees ( to know how many dgrees is is rised subtract the second number from the first number)
There are 2 ways we can answer this. The first one is by the given known coordinates we can make and get the equation. Next we can use the known coordinate and substitute it to the all given equations. It appears that only the third option is true after substituting the values. So the answer is C.
<span>C. y = x^2 + 6x − 7
x − y = 1</span>
