Answer:2 7/12 hours.
Step-by-step explanation: First, convert 1 3/4 to improper fraction form which will give you 7/4. Then find the common denominator of 5/6 and 3/4. The common denominator is 24. 5/6=20/24. 7/4=42/24. 20/24+42/24= 2 7/12.
The possible ordered pairs whose product will be negative (less than zero) are,

That is all these products will give us,


The point must be in the second quadrant where x is negative and y is positive.
Or in the fourth quadrant, where y is negative and x is positive.
I don't have the answer for the second one, but the answer to number 1 is 9.
6÷2(1 + 2) =
6÷2(3) =
3(3) =
9
Answer:
a= 2/b-c
Step-by-step explanation:
We want isolate for a or to be itself
ab-ac=2
factor out a
a (b-c)=2
Now bring b-c to the other side
a (b-c)/(b-c)=2/b-c
The b-c cancel each other out
a= 2/(b-c)
To answer this item, we let x represent the original price of the object or the fridge before it happened.
The representation would lead us to conclusion that the total amount to be paid is equal to,
1.20x = £480
The value of x from the equation,
x = 400
The answer is <span>£</span>400
