Answer:
√3
Step-by-step explanation:
We cannot solve this operation directly. Because cot7pi/6 is undefined.
We know that 1/tan= cot.
so we will first take the reciprocal of cot that is 1/tan.
So,
cot7pi/6= 1/tan 7π/6
∵7π/6 = 210 where pi=180
so cot7π/6 =1/tan210
cot7π/6 =1/1÷√3
cot7π/6 = √3
First you need to set up your equation.
If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:
3x+7= 2x+18
You want to find out x in both equations so I’ll help step by step
1. Subtract 2x from both sides
This leaves you with x+7=18
2. Then subtract 7 on both sides
This leaves you with x=11
So x equals 11 for equations.
You can check by plugging in 11 in x. If you get 40 on both sides....
CONGRATS!! You did it
I hope this helped. Have a great day!
Work backwards. If there were 14 at the end, then multiply this by 3/2 because 2/3 of the marbles were given to Sam. so 14 times 3/2 is 21. There were 28 total because if you add 1/3 to 1/6 you get 1/2. So they they lost 1/2 of the marbles and got 1/4 of the original amount back, which was 21.
So the original number was 28. Hope this helps!
