What does x equal? 5x = 2/7 ; x =
Pavlova-9 [17]

Answer:

it would be x=17 1/2

Step-by-step explanation:

i am going to go a little more into detail.

you would first have to divide each side to isolate the variable

x=5/2/7

simplifying steps:

you would have to change the 5 into 5/1

5/1÷2/7

now you have to keep the first number, change the sign, and then flip the last number, AKA KCF

5/1*7/2

35/2

and you can simplify this into a mixed number

17 1/2

hope this helps! have a nice day :)

Alexandria High School scored 37 points in a football game. Six points are awarded for each touchdown. After each touchdown, the
galben [10]

Answer:

Five touchdowns were made in the game

Step-by-step explanation:

Here, we want to know the number of touchdowns made during the game.

We proceed as follows;

Let the number of touch downs be x

So the total points earned through touchdowns is 6 * x = 6x

The number of scores is 10 times

Let the number of extra kick be y which means that the number of conversions will be (y-1)

So the total number of score times will be ;

x + y + y-1 = 10

x + 2y = 11 •••••••••(i)

Now let’s work with points

Touch down points = 6 * x = 6x

Points from extra kick = 1 * y = y

Points from 2-point conversions = 2(y-1) = 2y - 2

So;

6x + y + 2y -2 = 37

6x + 3y = 37 + 2

6x + 3y = 39

divide through by 3

2x + y = 13 •••••••(ii)

So now solve simultaneously

From ii, y = 13 - 2x

Put this into i

x + 2(13-2x) = 11

x + 26 - 4x = 11

x -4x = 11-26

-3x = -15

x = -15/-3

x = 5

There are five touchdowns in the game
