8. A
9. C
10. D
Those are the answers
You have to start within the parenthesis. To subtract fractions you need a common denominator. You'll get (3/4 - 2/4) Subtract them (1/4)and square both the top and bottom. (1/16) After that multiply by the 4. The number next to the parenthesis.(4/16 = 1/4) After that you add 5/4 to 1/4 and you'll get 6/4 which reduces to 3/2. That is the answer
A) 5
Two sides of a triangle have to be the same size. IF we aren't talking about a scalene.
In bank A, after one year this would be the amount in the bank:
<span>$7,000 x 1.04 = $7280. </span>
<span>He has gained %280 interest. This means you'd need $1000 interest from bank B. </span>
<span>$13,000 would go into bank B... </span>
<span>If Seth's interest rate was 8.69% you could calculate the interest as: </span>
<span>(13000 x 1.0869) - 13,000 = $1129.70 which is a little much (but who'd complain). </span>
<span>This means the interest is lower than this, if it was 7.69% you could just substitute it into the same equation to find that he would get $999.70 interest. This isn't exactly $1000 but it is the most accurate answer to the nearest $100 :) He would then get $1279.70 interest altogether.. just 30 cents short</span>
