I am assuming when you write 27x5 u mean "27 times x to the power of 5".
therefore, your answer is 9x3-11x2-7x
9/-1.........................
2.8 hours because 3.5 divided by 1.25 is 2.8
Step-by-step explanation:
Put 1 on the far left and 4 on the far right.
Put. 2 the top and 3 at the bottom.
Put 5 in the centre.
There are 2 ways you can find to to make all the numbers add up to 5.
The number in the centre is the common anwser to the sums.
I think x is equal to 14.7
