Answer:
15s
Step-by-step explanation:
Write like so:
54m = 9s
90m = x
Cross multiply:
(90*9)=(54x)
810 = 54x
Divide both sides by 54:
810/54 = 54x/54
15 seconds = x
Answer:
(5,0) and (0,6)
Step-by-step explanation:
1. Rearrange y as LHS
12x+10y=60
10y=60-12x
y=60/10-12/10x
y=-6/5x+6
2. Find intercepts
x = 0 is y intercept
y = 6
y = 0 is x intercept
-6=-6/5x
6=6/5x
30/6=x
x = 5
3. X-int (5,0) Y-int (0,6)

Answer: x^2
Step-by-step explanation: x times x is x^2
10x-20=180 6x+8
-20 -20 104
10
10x= 160
/10 /10
x=16
