Chen writes down a two digit number. He finds out that if he swapped the numbers, it would be three more than the 1/3 of the ori

inna [77]

Answer:

Step-by-step explanation:

From the information given,

Let the two digits that Chen writes down to be p and q

where,

q will be in the unit place and p will be in the tens place.

So, the value of the digit = 10p + q

So, if he swapped the number, he will have 10q + p

However,

the new number determined is thrice more than the 1/3 pf the original number.

i.e

the 1/3rd of the original number = $\dfrac{1}{3}(10p+q)$

= $\dfrac{10p+q}{3}$

thrice more than that will be = $\dfrac{10p+q}{3} + 3$

∴

$\dfrac{10p+q}{3} + 3 = 10q+p$

multiply through by 3, we have :

10p+q + 9 = 30q + 3p

collecting the like terms, we have:

10p - 3p +q -30q +9 = 0

7p - 29q +9 = 0

7p - 29q = -9

Therefore, p,q lie between 0 and 9

Therefore, the possibility of the original number is p = 7 and q = 2

Add: 3x+9+8x + 12 2x + 6+x² + 6x + 9

Oxana [17]

I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)

First one: 3x+9+8x + 12

Collect like terms and simplify

(3x+8x)+(9+12)

11x+21

Second one: 2x + 6+x² + 6x + 9

Collect like terms and simplify

$(2x+6x)+(6+9)+x^{2}$

8x+15+ $x^{2}$

Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

Subtract. Simplify, if possible. 5/8 - * 2 1 / 2 - 3

Nat2105 [25]

$2\frac{1}{2} - \frac{5}{8}$

Convert the mixed number to an improper fraction:

$\frac{5}{2} - \frac{5}{8}$

Subtract the fractions to get your final answer:

$\frac{15}{8}$
