Answer:
Each student would get more than 1 cup of broth.
Step-by-step explanation:
The teacher has 5 cups to split with 4 students.
- 5 cups/4 students = 1.25 cup of broth, which is also equalivent 1 1/4 cup of broth. 1.25>1 which means each student gets more than 1 cup of broth.
You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5
Answer:
The answer is d I just got that one:)
Y=-5.11111 how I solved it is in the picture attached
Hey there! :D
y=2x-9
We can plug that in as y, since y is equal to 2x-9.
5x-3(2x-9)= 23
Distribute.
5x-6x+27= 23
-1x+27=23
Subtract 27 on both sides.
-1x=-4
Divide both sides by -1.
x=4
Now, plug that in for y.
y=2(4)-9
y=8-9
y=-1
(4,-1) <== solution
I hope this helps!
