Mathematics

Cara's bill was $30.51 this week.

Cara's bill was $7.60 more than two-thirds of her grocery bill last week.

First thing we need to do therefore, is to find out what 2/3 of her bill was last week:

= 2/3 x 34.37

= $22.91

Her bill was $7.60 more than this amount so it was:

= 7.60 + 22.91

= $30.51

Cara's bill was therefore $30.51 this week.

In Juan's coin bank there are nickels (n),
alukav5142 [94]

Answer:

The answer is 8 quarters, 16 nickles, and 32 dimes

Step-by-step explanation:

  1. First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.)
  2. Then we slowly start to solve: 10/4d + 10d + 25/4d = 600
  3. 10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d)
  4. 75d= 600 x 4
  5. d=600 x 4/75 (same here put everything over 75)
  6. d=32
  7. So then n= 2 x 32/4 = 16
  8. Then n would be equal to : 1/4d= 1/4 x 32 = 8
  9. So your answer would be 8 quarters, 16 nickles, and 32 dimes.

Hope this helped :)

Please solve this...question..it may come in my exam.#math problem fast solve it and help me​
ehidna [41]

Answer:

n + y

Step-by-step explanation:

a² - b² = (a +b)(a - b)

\frac{n^{2}-y^{2}}{n+y} ÷ \frac{n - y }{n + y } = \frac{(n + y)(n - y)}{(n + y)}*\frac{(n + y)}{(n - y)}\\\\    

    { (n + y) in the denominator and numerator will be cancelled ;

       (n - y) in the denominator and numerator will be cancelled

                    = n + y
