I'm going to change those to 5/2 and 8/7
Dividing is the same multiplying by the reciprocal (reciprocal of x is 1/x, reciprocal of x/y is y/x)
So (5/2)/(8/7)=(5/2)*(7/8)=(5*7)/(2*8)=35/16
Final answer: 35/16
Step-by-step explanation:
Therefore, 55+40+z=180
z=180-95
z=85
To get y,
z+y=180
85+y=180
y=95
Answer:
1) -6/-10=3/5
2) -27/10x75/18 = -2025/180 = -135/12 (or) -11 1/4 (or) -11.25
3) 7+8-9=6
4) Billions
5) No, because you can't take a negative number of classes

Answer:
7.03 seconds
Step-by-step explanation:
First, you need to differentiate the equation (The derivative of y represents the rocket's velocity):
y' = 32x + 225
Then, set y' to 0 and solve for x
0 = 32x + 225
x = 7.03s
