Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
n - 7 = 9
Step-by-step explanation:
so basically just make up a random variable and place it for the "twice a number" then u sovle it as a 2 step equation
MDC and largest number that can divide two numbers while
<span>340.728 2 </span>
<span>170.364 2 </span>
<span>85 182 </span>
<span>the highest numeropossivel that can divide two numbers are the same times 4 = 2.2</span>
Answer:
B
Step-by-step explanation:
x is the value of x which you input into the function and f(x) is the actual function and therefore the output. so when x=3, f(x)= -2. f(3)=-2
