What two numbers can equal to 70 when added in 34 when subtracted.

lina2011 [118]

Answer:

18 and 52

Step-by-step explanation:

x + Y = 70

X - Y= 34 find the value of X interms of Y to find the answer:

X - Y= 34

X = 34 +Y

x + Y = 70

(34 + Y ) + Y = 70

34 + Y +Y = 70

2Y =70-34

2Y/2=36/2

Y = 18

x + 18 = 70

x=70 - 18

x= 52

check:

18 + 52= 70

52 - 18= 34

C)36

1)Since X=2 and y=4, in order to evaluate it. Let's plug it in those values.

But firstly, we need to apply the Distributive Property.

x+y+3(x+2y)

x+y+3x+6y

2) Now let's add the similar terms

x+3x +6y+y

4x+7y

3) Plugging in

4(2)+7(4)

8+28

Nadusha1986 [10]

To get the total number of games possible, we will use the combination formula.
Total number of games : $_{10}C_{2}$ = 45

Total of 45 games in the whole tournament.

Meanwhile, if there would be boy-versus-boy, we will have $_{5}C_{2}$
The answer is 10.

The fraction for boy-versus-boy game will be 10/45 or 2/9 when simplified.
