Answer:

2 or 12

Step-by-step explanation:

The answer that we will use this equation 1/t1 +1/t2=1/ttotal

where t1 is the time of smaller pipe while t2 is the of the larger pipe

Given t total =4 while t2 is equal to t2=t1-6

So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4

8( t1-3)=(t1^2-6t1)

t1^2-14t1+24=0

t1=2 or 12

Elvira is 5 years older than Morton. Morton is twice as old as Michelle. The combined total of their ages is 85. How old is Mort
LiRa [457]

Elvira (e) is 5 years older than Morton (m)

e = m + 5

Morton (m) is twice as old as Michelle (c)

m = 2c

The combined total of their ages is 85

e + m + c = 85

We want m at the end so let's write everything in terms of m.

e = m + 5

c = m/2

85 = e + m + c = m+5 + m + m/2 = 5 + (5/2) m

m = (2/5) (85 - 5) = 32

Answer: 32 years old

Check:

That makes Elvira 37 and Michele 16, total 32+37+16=85, good

Given f(x) = 10 -2xfind f(7). –4 3 7 56
strojnjashka [21]

Answer: f(7)=-4

Step-by-step explanation:

1. You have the following function given in  the problem:

f(x)=10-2x

2. Then, to find f(7) asked in the exercise, you only need to substitute x=7 (which is the input value) into the given function.

3. Therefore, keeping the above on mind, you obtain that f(7) is:

x=7

f(7)=10-2(7)

f(7)=10-14

f(7)=-4
