The sum of a 3 digit number and a 1 digit number is 217. The product of the numbers is 642. If one number is between 200 and 225
algol [13]
Let, the numbers be "x" and "y". Consider "x" as the triple digit number.
Now, according to the question,
x + y = 217..........................equation (1)

x * y = 642............................equation (2)

Now,
Taking equation (2),
x * y = 642
y = 642 / x..................................equation (3)

Now, Taking equation (1),
x+y=217

Substituting the value of y from equation (3), we get,

x+ \frac{642}{x} =217

\frac{x *x+642}{x} =217

x^{2} +642 =217*x

x^{2} +642 =217x

x^{2} +642-217x =0

x^{2} -217x+642 =0

x^{2} -3x-214x+642 =0

x(x-3)-214(x-3)=0

(x-3)(x-214)=0

Using zero product property,
EITHER,
           x - 3 = 0
                x = 3
OR,
          x - 214 = 0
                  x  = 214
Since, "x" is the triple digit number, x = 214.
Now,
Taking equation (2),
x * y = 642
Substituting the value of "x" in the equation, we get,
(214) * y = 642
y = 642 / 214
y = 3

So, the numbers are 214 and 3.

What is the value of x in the figure?<br> A. 10<br> B. 6<br> C. 15<br> D. 12
Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

You need to set up a proportion.

(21 - 15) / 21  = 4/(x + 4)

6 / 21 = 4/(x + 4)

2/7 = 4/(x + 4)

2(x + 4) = 7*4

2x + 8 = 28

2x + 8-8= 28 - 8

2x = 20

x = 20/2

x = 10
