7
Step-by-step explanation:
To find the fifth term in the sequence, plug in 5 for n.
a₅=2(5)-3
Then just solve
a₅=10-3
a₅=7

Step-by-step explanation:
3/8 x £40 = £15 for Sarah
3/8 x £40 = £15 for Fiona
2/8 x£40 = £10 for david
Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
Okay so first what you would have to do is to read the question carefully and understand it because if you don't read the question, well the thing is you could get it wrong. and so first see what the question is and then understand it and once you'd understand it, solve it. So what you would have to do is tell the property is using and think about how the question is written and think of the properties you have studied. Well you might as well notice that its the associative property because if you don't have parenthesis around your problem, it wouldn't be as organized as it should be because if you don't follow the Associative Property, it could confuse you. And so the answer to this problem would be a more good or sensible answer because you used the properties to help you and so your final answer to this problem would be 2,700 as your final answer and keep in mind that if you use properties it would be a much easier problem to solve. And so thank for your question and have a blessed day and May God bless you and I hope this helped you out with your question you asked and so thank you again and so see you again. Bye !!!
Hi. 2 (×+1)=3×-1 ; 2x+2= 3x-1 ;
2x-3x= -1-2 ; -x = -3 ; x=3. Hope this helps.
