Simply divide the whole by the two HCF, Such as 5 and 3, and 7 and 3.
Answer:
12km/h
Step-by-step explana:
Let's call the total distance 2a from which we can calculate t1 equivalent to the first half of the distance a/10 similar to t2 is a/15 from which the total time is a/6 . We have the average speed equal to the total distance dduowcngf divided by the total inferred time by 2a/(a/6) which equals 12km/h
Hey there! I'm happy to help!
If we have g(-3) we plug -3 into our function as x.
-3-2(-3)²
-3-2(9)
-3-18
-21
g(-3) is -21, so now we just add 13.
-21+13=-8
The answer is -8.
Have a wonderful day! :D
Answer:
use a calculator
Step-by-step explanation:
As given, let Jim's rate = x
Let Pete's rate =y
Jim completed half the floor in 12 hours so it's
= 12x
Pete completed the other half of the floor in 10 hours so its
=10y
As floor area is equal so,
.............(1)
Now, given is that Pete can lay 25 more tiles per hour than Jim, this gives=
...... (2)
Putting the value of y from equation (2) in equation (1) , we get

So, the equation is : 
If you want to solve it, it becomes:



Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.
