Answer:
x=27
Step-by-step explanation:
expanding the above expression we get
5x+5=4x+32
grouping numbers with coefficient of x at the left side and constant at the right side we get
5x-4x=32-5
x=27
Answer:
-9x^2 - 15x.
-3x.
Step-by-step explanation:
The first quotient is -9x^2 - 15x.
To find the second result we divide the above by 3x + 5:
-3x

They'll meet at the court again in 60 days after this monday.
Step-by-step explanation:
In order to calculate the number of days from monday that it will take for them to meet again, we need to calculate the LMC of the frequency at which they go to the court. To do that we must take the numbers and divide the 3 of them until they're all equal to 1, then we multiply all the numbers that were used to divide them.
12 | 10 | 6 / 2
6 | 5 | 3 /2
3 | 5 | 3 /3
1 | 5 | 1 /5
1 | 1 | 1
The LMC is equalt o 2*2*3*5 which is 60.
They'll meet at the court again in 60 days after this monday.
