Solving the system of equations, we get value of c= 10 and value of d= 7

Step-by-step explanation:

Solving the system of equations:

c+d=17\\c-d=3

Let:

c+d=17\,\,\,eq(1)\\c-d=3\,\,\,eq(2)

Adding eq(1) and eq(2)

c+d=17\\c-d=3\\------\\2c+0d=20\\c=20/2\\c=10

So, value of c = 10

Now putting value of c in equation 1 to find value of y

c+d=17\\10+d=17\\d=17-10\\d=7

So, value of d =7

Solving the system of equations, we get value of c= 10 and value of d= 7

(1 point) Rework problem 15 in section 2 of Chapter 5 of your textbook about the growing suburb and the declining city using the
Vanyuwa [196]

Answer:

16 years

Step-by-step explanation:

Let x represent the number of years. The suburb population is growing at a rate of 5000 per year after x years, it can be represented by the equation:

320000 + 5000x

The city population is declining at a rate of 14000 per year after x years, it can be represented by the equation:

624000 - 14000x

The number of years for the city and suburb population to be equal can be gotten from:

320000 + 5000x = 624000 - 14000x

14000x + 5000x = 624000 - 320000

19000x = 304000

x = 304000 / 19000

x = 16

In 16 years the populations of the suburb and the city be equal

Fred is making a bouquet of carnations and roses. The carnations cost $5.25 in all. The roses cost $1.68 each. How many roses di
olga nikolaevna [1]

Answer:

8 roses

Step-by-step explanation:

First start by subtracting $18.69 by $5.25 because you already know how much the carnations cost and how much the bouquet cost in all. When you subtract 18.69 by 5.25 you should get $13.44. If each rose cost $1.68 then divide 13.44 by 1.68 to get the amount of roses in the bouquet.
