Answer:

The system of equations is:

        x + y = 15

           xy = 15

Step-by-step explanation:

solve the first for y and substitute in the second:

            y = 15-x

      x(15-x) = 15

     15x - x� = 15

15x - x� - 15 = 0

-x� + 15x - 15 = 0

x� - 15x + 15 = 0

Answer:

  x + y = 15

          xy = 15

Step-by-step explanation:

           y = 15-x

     x(15-x) = 15

    15x - x ? = 15

15x - x ? - 15 = 0

-x ? + 15x - 15 = 0

x ? - 15x + 15 = 0

Hope you get it right!!

Estimate the sum 8/10 + 1/9
RideAnS [48]

Answer:

41/45

Step by Step Explanation:

Add: 8/

10

+ 1/

9

= 8 · 9/

10 · 9

+ 1 · 10/

9 · 10

= 72/

90

+ 10/

90

= 72 + 10/

90

= 82/

90

= 2 · 41/

2 · 45

= 41/

45

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 9) = 90. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 9 = 90. In the following intermediate step, cancel by a common factor of 2 gives 41/

45

.

In other words - eight tenths plus one ninth = forty-one forty-fifths.
