Answer:
x =38/5
Step-by-step explanation:
(x – 2) = –14(x – 8)
Distribute
x-2 = -14x+112
Add 14x to each side
x-2+14x = -14x+14 +112
15x-2 = 112
Ad 2 to each side
15x-2+2 = 112+2
15x= 114
Divide each side by 15
15x/15 = 114/15
x=114/15
Divide top and bottom by 3
x =38/5
Answer:
the answer is x<-1
Step-by-step explanation:
-6x + 22 1/4 +2x> 9 3/4+ 16 1/2
-4x +89/4 >(9+26) + (3/4+1/2)
-4x + 89/4 > 25+ (3/4 + 1/2)
-4x + 89/4 >25 +1 1/4
-4x 89/4 > 25 + 1 + 1/4
-4x + 89/4 > 26+ 1/4
-4x + 89/4 > 26 1/4
-4x + 89/4 > 105/4
-4x > 105/ 4 -89/4
-4x> 4
x <-1
Answer: 3 8/10
Step-by-step explanation:
You have 6. First of all, you subtract 3 frome 6. Then you have 10s. Subtract 2 of the 10s and then you will get 3 and 8/10. I hope my explanation helps you out!

Answer:</h3>
6 hours
<h3>
Step-by-step explanation:</h3>
The two hoses together take 1/3 the time (4/12 = 1/3), so the two hoses together are equivalent to 3 of the first hose.
That is, the second hose is equivalent to 2 of the first hose. Two of the first hose could fill the vat in half the time one of them can, so 6 hours.
The second hose alone can fill the vat in 6 hours.
_____
The first hose's rate of doing work is ...
... (1 vat)/(12 hours) = (1/12) vat/hour
If h is the second hose's rate of doing work, then working together their rate is ...
... (1/12 vat/hour) + h = (1/4 vat/hour)
... h = (1/4 - 1/12) vat/hour = (3/12 -1/12) vat/hour = 2/12 vat/hour
... h = 1/6 vat/hour
so will take 6 hours to fill 1 vat.
