Answer:

about x=38.1

Step-by-step explanation:

9x38.1=342.9

The algebraic expression is:

x + (2x - 11) = 13

And the solution is x = 8.

Let's say that the number is defined by the variable x, then we can write the algebraic expression:

x + (2x - 11) = 13

Now we can solve this expression for x:

x + 2x - 11 = 13

3x = 13 + 11 = 24

x = 24/3 = 8

x = 8

The solution is x equal to 8.

Answer:

Milk and Eggs = 552

Step-by-step explanation:

First add all of the other percentages together. (70%), 100%-70%=30%. 30% of 1840 = 552.

Answer:

H.  552

Step-by-step explanation:

Circle graph information:

Total consumption = 1840 pounds per person

First, calculate the percentage of milk and eggs (the value of x).

Total percentages = 100%

⇒ x + 38 + 10 + 10 + 8 + 4 = 100

⇒ x + 70 = 100

⇒ x = 30

Therefore, 30% of food consumption is milk and eggs.

To calculate the number of pounds of milk and eggs the average American consumes each year, simply find 30% of the total consumption:

= 30% of 1840

= 30% × 1840

[tex]=\sf \dfrac{30}{100} \times 1840[/tex]

= 552

Therefore, the average American consumes 552 pounds of milk and eggs each year.

Ethan= x(14) + (20)(1.50)

Roy = x(13.50) + (20)(1.80)

Since they collected the same amount of money:

Combine like terms:

14x - 13.50x = (20)(1.80) - (20)(1.50)

Answer:

6 seconds after it is launched

Step-by-step explanation:

h(t) = -4t² + 16t + 48

The balloon is at ground level when it lands.

When it is launched, t = 0, and h(0) = 48

When it lands, at time t, h(t) = 0.

-4t² + 16t + 48 = 0

t² - 4t - 12 = 0

(t - 6)(t + 2) = 0

t = 6 or t = -2

The balloon will hit the ground 6 seconds after it is launched.

The x-intercepts of the parabola are (3, 0) and (7,0)

The given parameters are:

Vertex (h, k) = (5, -12)

Point (x, y) = (0, 63)

The equation of a parabola is:

y = a(x - h)^2 + k

Substitute (h, k) = (5, -12)

y = a(x - 5)^2 - 12

Substitute (x, y) = (0, 63)

63 = a(0 - 5)^2 - 12

Evaluate

63 = 25a - 12

Add 12 to both sides

25a = 75

Divide by 26

a = 3

Substitute a = 3 in y = a(x - 5)^2 - 12

y = 3(x - 5)^2 - 12

Set y to 0 to determine the x-intercepts

0 = 3(x - 5)^2 - 12

Add 12 to both sides

3(x - 5)^2 = 12

Divide by 3

(x - 5)^2 = 4

Take the square root of both sides

[tex]x - 5 = \pm 2[/tex]

Add 5 to both sides

[tex]x = 5 \pm 2[/tex]

Expand

x = (5 - 2, 5 + 2)

Evaluate

x = (3, 7)

Hence, the x-intercepts of the parabola are (3, 0) and (7,0)

Answer:

  (a)  (5, -3)

Step-by-step explanation:

The "substitution method" for solving a system of equations requires that you write an expression that can be substituted for a variable in one or more of the other equations in the system.

The given equations are ...

We notice the first equation gives an expression for y. This is exactly what we want to substitute for y in the second equation.

When the expression (x-8) is substituted for y in the second equation, you get ...

  2x +3(x -8) = 1

This simplifies to ...

  5x -24 = 1

This 2-step equation can now be solved in the usual way:

  5x = 25 . . . . . . add 24 to isolate the variable term

  x = 25/5 = 5 . . . . . divide by the coefficient of x

Note that we now know what the correct answer choice is.

Using the expression for y, we find ...

  y = x -8 = 5 -8 = -3

The solution is (x, y) = (5, -3).

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The given triangle can be solved as shown below.

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ B}{\beta} =\dfrac{Sin\ C}{\gamma}[/tex]

where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,

Sin B is the angle and β is the length of the side of the triangle opposite to angle B,

Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.

For the given triangle, using the sine rule the ratio of the angle and the sides of the triangle can be written as,

[tex]\dfrac{Sin\ A}{18} =\dfrac{Sin\ B}{11} =\dfrac{Sin\ C}{c}\\\\\dfrac{Sin\ 72^o}{18} =\dfrac{Sin\ y^o}{11} =\dfrac{Sin\ x^o}{c}[/tex]

Taking the first two ratios,

[tex]\dfrac{Sin\ 72^o}{18} =\dfrac{Sin\ y^o}{11}\\\\y = 35.54^o[/tex]

The sum of all the angles of a triangle is 180°.

72° + 35.54° + x° = 180°

x = 72.46°

Now, using the sine ratio,

[tex]\dfrac{Sin\ 72^o}{18} =\dfrac{Sin\ 72.46^o}{c}\\\\c = 18.046[/tex]

Answer:

y=3/2x + 18

Step-by-step explanation:

So when two lines are perpendicular, that simple means the slope are reciprocals, and the signs are opposite. So for example if one equation had a slope of [tex]\frac{a}{b}[/tex], the equation that is perpendicular, would have a slope of [tex]-\frac{b}{a}[/tex]. So the first step would be to find the slope of 2x+3y=4. To find the slope we can convert it into slope-intercept form which is y=mx+b where m is the slope, and this is done by isolating y, as you can see the y is alone in the slope-intercept form.

Original equation:

2x + 3y = 4

subtract 2x from both equations:

3y = -2x + 4

Divide both sides by 3

y = -2/3x + 4/3

The y-intercept doesn't really matter in this case, what really matters is the slope, and the slope is the coefficient of x, since as x increases by 1, it will increase by the amount of the coefficient, because the slope is rise/run and since the run is 1, if you increase x by 1, the run is the slope, which is the coefficient. The slope in this case is -2/3. So the reciprocal of the slope is 3/2 (notice how the sign is the opposite as well). Now we have the equation

y=3/2x + b

To find the y-intercept, you simply use the point that was given (-2, 15). Plug in -2 as x, and 15 as y to find the value of b

Original equation

y=3/2x + b

Plug in known values:

15 = 3/2(-2) + b

Multiply the fraction:

15 = -6/2 + b

Simplify the fraction:

15 = -3 + b

Add 3 to both sides

18 = b

This gives you the equation

y=3/2x + 18

The value of x is 4.
