-39, -37, -35, -33, -31, -29. Odd numbers are the same just backwards ;)
1.Simplified each one
2/5 (both divided by 7) , 1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10 , (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5
Answer:
$4,208.5
Step-by-step explanation:
The simple interest rate of the college savings account, R = 5.5%
The amount with which the account was opened, P = $500
The amount added each month to her account = $50
The amount in her account after 4 years = Required
The interest on each added $50 is given as follows;
50 × 0.055/12 × (1 + 2 + 3 + ... + 47) = 50 × 0.055/12 × (47/2)(1 + 47) = 258.5
The total amount deposited = 500 + 50 × 47 = $2,850
The total interest = 500×0.55×4 + 50 × 0.055/12 × (47/2)(1 + 47) = 1,358.5
The amount in her account at the end of 4 years, <em>A</em>, is given as follows
A = $2,850 + $1,358.5 = $4,208.5
ANSWER
A. Noah is correct because the two sides of the equation are equivalent expressions.
EXPLANATION
The equation given to Noah was
He expanded to get:
He then further simplified each side of the equation to get;
Both sides of this equation are equivalent.
Therefore the equation has infinitely many solutions.
The correct answer is A
