Find the value of x (Round to the nearest tenth)




Help plssssssssss

Answer:

 y  = 3x + 3

Step-by-step explanation:

Given parameters;

 Coordinates of the line;

            (-2, -3)

  Slope of the line  = 3

Unknown:

Equation of the line = ?

Solution:

The equation of any straight line is often expressed as;

            y  = mx + c

y and x are the coordinates

c is the intercept

  Now insert values of y, x and m to find c;

   -3  = 3(-2) + c

   -3  = -6 + c

    c = -3 + 6  = 3

The equation of the line is;

         y  = 3x + 3

Answer: y = 3

Step-by-step explanation:

4(-1)+8y=20

negative * positive = negative

-4+8y=20

add 4 on both sides to isolate 8y

8y = 24

divide each side by 8

y = 3

Answer:

[tex]y=3[/tex]

Step-by-step explanation:

Step-By-Step on how to solve for y is in the attached picture.

Hope this helps! :)

Step-by-step explanation:

x/6+1/5=2

30(x/6+1/5)=30(2)

5x+6=60

5x=60-6

5x=54

divide both sides by 5

therefore, x is equal to 10.8

Answer:

b. 5x + 4y = 80

Step-by-step explanation:

Let us assume the remaining balance left be Y

and, the number of songs purchased be X

Given that

Wins a gift card of $20

And, the songs purchased is 16

Now if we take the fraction

= 20 ÷ 16

= 5 ÷ 4

So if we reverse this fraction

So it could be 5x and 4y

And, the amount that would come is

= $20 × 16 ÷ 4

= 80

So, the equation is 5x + 4y = 80

Hence, the correct option is b.

Answer:

0 = 7m

0 = m

m = 0

It is 0 because first you would have to cancel -10 on both of the sides then divide both of the sides by 7 then switch the sides which is 0

The result of the equation -10 = -10 + 7m is m = 0

The given equation is:

-10  =  -10   +  7m

Add 10 to both sides of the equation

-10  +  10   =  -10  +  10  +  7m

0   =   7m

Rewrite the equation as:

7m   =  0

Divide both sides of the equation

7m/7   =  0/7

m  =  0

This is because 0 divided by any number is 0

Therefore, the result of the equation -10 = -10 + 7m is m = 0

Answer:

29 minutes

Step-by-step explanation:

Given

[tex]Total = \$43.25[/tex]

[tex]Entrance\ Fee = \$7[/tex]

[tex]Per\ Minute = \$1.25[/tex]

Required

Determine the number of minutes (t) that he was on the trampoline.

This can be expressed as:

[tex]Total\ Payment = Entrance\ Fee + Amount\ per\ minute * t[/tex]

Where t represents the number of minutes

Substitute values for Total, Entrance Fee and Amount per minute

[tex]43.25 = 7 + 1.25 * t[/tex]

[tex]43.25 = 7 + 1.25t[/tex]

Solving further to get the value of t, we have:

[tex]1.25t = 43.25 - 7[/tex]

[tex]1.25t = 36.25[/tex]

[tex]t = 36.25/1.25[/tex]

[tex]t = 29[/tex]

Answer:

29 minutes

Step-by-step explanation:

7 + 1.25t = 43.25 is the equation

How did I solve this?

I divided those two and that is how you get the equation

In total is 29 minutes

I did the Khan and it was right!

An angle is a mathematical term which we can defined, when two straight lines or rays meets at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The  inner angle made by the intersection of two polygonal sides.

Exterior angles:-  The  outer angle made by the intersection of two polygonal sides.

Given that,

All the exterior angles are,

(5x + 4), (7x + 4),(4x + 9),(4x + 1),(9x-6)

It is known that,

Sum of Interior angle & Exterior angle is equal to 180°

So we can calculate all the Interior angles,

180°- (5x + 4),  180°-(7x + 4),   180°-(4x + 9),   180°-(4x + 1),    180°-(9x-6)

Formula for sum of all the Interior angles = (2n-4)×90

So, n=5

Sum of all the Interior angles = 540°

[180°- (5x + 4)] + [180°-(7x + 4)]+[180°-(4x + 9)]+[180°-(4x + 1)] +[180°-(9x-6)] = 540

900- 29x- 12 = 540

x = 12

Hence, The value of x is, 12

Answer:

t = 4

Step-by-step explanation:

Solve for t:

8 - (7 t)/10 = 6 - t/5

Hint: | Put the fractions in 8 - (7 t)/10 over a common denominator.

Put each term in 8 - (7 t)/10 over the common denominator 10: 8 - (7 t)/10 = 80/10 - (7 t)/10:

80/10 - (7 t)/10 = 6 - t/5

Hint: | Combine 80/10 - (7 t)/10 into a single fraction.

80/10 - (7 t)/10 = (80 - 7 t)/10:

1/10 (80 - 7 t) = 6 - t/5

Hint: | Put the fractions in 6 - t/5 over a common denominator.

Put each term in 6 - t/5 over the common denominator 5: 6 - t/5 = 30/5 - t/5:

(80 - 7 t)/10 = 30/5 - t/5

Hint: | Combine 30/5 - t/5 into a single fraction.

30/5 - t/5 = (30 - t)/5:

(80 - 7 t)/10 = (30 - t)/5

Hint: | Make (80 - 7 t)/10 = (30 - t)/5 simpler by multiplying both sides by a constant.

Multiply both sides by 10:

(10 (80 - 7 t))/10 = (10 (30 - t))/5

Hint: | Cancel common terms in the numerator and denominator of (10 (80 - 7 t))/10.

(10 (80 - 7 t))/10 = 10/10×(80 - 7 t) = 80 - 7 t:

80 - 7 t = (10 (30 - t))/5

Hint: | In (10 (30 - t))/5, divide 10 in the numerator by 5 in the denominator.

10/5 = (5×2)/5 = 2:

80 - 7 t = 2 (30 - t)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

80 - 7 t = 60 - 2 t

Hint: | Move terms with t to the left hand side.

Add 2 t to both sides:

2 t - 7 t + 80 = (2 t - 2 t) + 60

Hint: | Look for the difference of two identical terms.

2 t - 2 t = 0:

2 t - 7 t + 80 = 60

Hint: | Group like terms in 2 t - 7 t + 80.

Grouping like terms, 2 t - 7 t + 80 = 80 + (2 t - 7 t):

80 + (2 t - 7 t) = 60

Hint: | Combine like terms in 2 t - 7 t.

2 t - 7 t = -5 t:

-5 t + 80 = 60

Hint: | Isolate terms with t to the left hand side.

Subtract 80 from both sides:

(80 - 80) - 5 t = 60 - 80

Hint: | Look for the difference of two identical terms.

80 - 80 = 0:

-5 t = 60 - 80

Hint: | Evaluate 60 - 80.

60 - 80 = -20:

-5 t = -20

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -5 t = -20 by -5:

(-5 t)/(-5) = (-20)/(-5)

Hint: | Any nonzero number divided by itself is one.

(-5)/(-5) = 1:

t = (-20)/(-5)

Hint: | Reduce (-20)/(-5) to lowest terms. Start by finding the GCD of -20 and -5.

The gcd of -20 and -5 is -5, so (-20)/(-5) = (-5×4)/(-5×1) = (-5)/(-5)×4 = 4:

Answer:

3 (m^2 - 16)

Step-by-step explanation:

factoring means taking out a common multiple of all the terms in the expression

in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48​

so you take the three and put it outside of the parenthesis that contains the factored terms

this leaves you with 3 (m^2 - 16)

Answer:

42mm

Step-by-step explanation:

Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.

5x+6x+8x = 159.6

19x = 159.6

x = 159.6 ÷ 19

x = 8.4

Shortest side of triangle (5x) = 8.4 × 5

                                               = 42

Answer:

this shape consists of a square and triangle

The shape is a Pentagon ... but that won't help get the perimeter or area. you'll have to find the areas and perimeters of both the square and triangle and then add them for the final answer.

Area of figure = area of square + area of triangle

=> Area of Square = a² (a = side)

side = 3.5 cm ...so...

Area of square = a²

= 3.5 × 3.5

= 12.25 cm²

=> Area of Triangle = ½ × base × height

= ½ × 3.5 × 1.64

= 2.87cm²

Area of figure = area of square + area of triangle

Area of figure = 12.25 + 2.87

= 15.12 cm²

Perimeter of figure = P of square + P of triangle

=> P of square = 4a

= 3.5 × 4

= 14cm

=> P of isosceles triangle = 2a + base

= 2 × 2.4 + 3.5

= 4.8 + 3.5

= 8.3cm

Total perimeter of figure = P of square + P of triangle

Total perimeter = 14 + 8.3

= 22.3 cm
