Answer:

-2

Step-by-step explanation:

Opening bracket,

6x+15 +4=7

6x=7-19    (I took 15 and 4 to other side and thus they became negative)          

x=-12/6

x=-2

Pls mark me brainliest

Answer:

The answer is x = -2

Step-by-step explanation:

FOIL

3*2x + 3*5 + 4 = 7

6x + 15 + 4 = 7

6x + 19 = 7

Subtract 19 from both sides.

6x =  -12

Divide both by 6.

x = -2

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

Answer:

x = -15/-3

Step-by-step explanation:

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 + 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

Answer:

Your answer is: x = -9

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

19=7-2x

12=-2x

x=-6

Answer:

x = 2

Step-by-step explanation:

x - 5x + 19 = 10 + 2x - 3

-4x +19 = 7 + 2x

4400 Yards

Step-by-step explanation:

A mile equals 1,760 yards. 2.5 times 1,760 gives you 4,400

It is given that A class walked 2.5 miles for a walk-a-thon then the class walked 4400 yards.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that A class walked 2.5 miles for a walk-a-thon.

WE are asked How many yards did the class walk.

A mile equals 1,760 yards.

If one mile is 1760 yards, then the answer should be

= 1760 times the number of miles.

So  1760*2.5 = 4400

Hence, the class walked 4400 yards.

Answer:

Options A and C

Step-by-step explanation:

Area of the triangular pane = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                              = [tex]\frac{1}{2}(14)(12)[/tex]

                                              = 84 cm²

Area of the rectangle is given by the formula,

Area = Length × width

Option A.

Area of the rectangular pane = 12 × 7

                                                 = 84 cm²

Option B.

Area of the rectangular pane = 15 × 7

                                                 = 105 cm²

Option C.

Area of the rectangular pane = 21 × 4

                                                 = 84 cm²

Option D.

Area of the rectangular pane = 21 × 8

                                                 = 168 cm²

Option E.

Area of the rectangular pane = 28 × 6

                                                 = 168 cm²

Therefore, rectangular panes A and C have the equal area as the triangular pane has.

B.-7/25

Step-by-step explanation:

edge

The required value of cos(2x) is -7/25. Option B is correct.

sinx = 4/5
cosx < 0

Trigonometry is the study of angles in mathematics.

Here,
cos(2x) = 1-2sin²x
           = 1 - 2 x 4²/5²
           =  1 - 32/25
cos(2x) =  -7/25

Thus, the required value of cos(2x) is -7/25.
