Answer:
6400 AED
9.14%
yes. The interest rate is 9.14%. This is less than 10%
Step-by-step explanation:
Interest amount she would pay = total of loan to be repaid - amount borrowed
16,400 - 10,000 = 6,400 AED
Interest = loan x interest rate x time
we have all the parameters of the above equation apart from the interest rate. We can thus determine the interest rate from the above equation
6,400 AED = 10,000 x interest rate x 7
6,400 AED = 70,000 x interest rate
Divide both sides by 70,000 to find a value for interest rate
interest rate = 0.091429 = 9.14%
To subtract fractions, we need an lcd( lowest common denominator)
8. the lcd is 42 because it’s the smallest number that 6 and 7 are both factors of. the lcd is the bottom of the fraction
to make the denominator of (4/7) 42, we will multiply the top and bottom by 6 and we get (24/42)
to make the denominator of (3/6) 42, we will multiply the top and bottom by 7 and we get (21/42)
these two numbers now have the same denominator so we subtract them
24/42 - 21/42 = 3/42 which simplifies to 1/14
9. since these fractions already have a common denominator, we will make them mixed fractions
-5(2/7) as a mixed fraction. first multiply 5*7 which is 35. now add 2 which is 37. our mixed fraction is -37/7
-1(5/7) as a mixed fraction. multiple 1*7 which is 7. now add 5 which is 12. our mixed fraction is -12/7
now subtract (-37/7) - (12/7) and we get -49/7 which simplifies to -7
The answer to the question is <span>B) The signs of the coordinates change.

Answer:
u=2/2a-1
Step-by-step explanation:
a=1/u +1/2
you find the LCM first which is 2u
a=2+u/2u
cross multiply
2au=2+u
subtract u from both sides
2au-u=2
u is common to the right hand side
u(2a-1)=2
divide through by 2a-1
u=2/2a-1
