Answer:

11 = x

Step-by-step explanation:

58+5x+10 = 11x+2

68+5x = 11x+2

    -5x = -5x

68 = 6x+2

-2          -2

66 = 6x

66/6 = 6x/6

11 = x

Hope this helps!

Answer:

x = 11

Step-by-step explanation:

58 + 5x + 10 = 11x + 2

First, combine like terms

68 + 5x = 11x + 2

Subtract 5x from both sides of the equation

68 = 6x + 2

Subtract 2 from both sides of the equatino

66 = 6x

Divide both sides by six to get your answer

11 = x

Answer:

a)   Number of laundry he can do with this box  = 78 laundries.

b)   Price he paying for each load =  0.256 $

Explanation:

Total scoop contained in detergent box = 195 scoops.

Scoops used by each load of laundry =  scoops = 2.5 scoops

Number of laundry he can do with this box = 195/2.5 = 78 laundries.

Price of detergent box = 19.99 $

Price he paying for each load = Total price/ Number of loads

                                                  = 19.99/78

                                                  = 0.256 $

FIRST ONE GOES WITH 5TH ONE 2 ONE GOES WITH 1 ONE AND LAST ONE GOES WITH 4 TH ONE

Answer:

first one is 135xy^2-30xy

the second one is 4x^3(x^2-2x-1)

Step-by-step explanation:

You can't simplify it any more than it is right now.

Given:

The height of ball is represented by the equation is

[tex]h=-16t^2+6t+4[/tex]

To find:

The time taken by ball to hit the ground.

Solution:

First we need to find the zeroes of the given equation. So, for zeroes h=0.

[tex]-16t^2+6t+4=0[/tex]

Here, [tex]a=-16,b=6,c=4[/tex]. Usingquadratic formula, we get

[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]t=\dfrac{-6\pm \sqrt{6^2-4(-16)(4)}}{2(-16)}[/tex]

[tex]t=\dfrac{-6\pm \sqrt{36+256}}{-32}[/tex]

[tex]t=\dfrac{-6\pm \sqrt{292}}{-32}[/tex]

[tex]t=-\dfrac{-6+ 17.088}{-32},\dfrac{-6+ 17.088}{-32}[/tex]

[tex]t=0.7215,-0.3465[/tex]

Time cannon be negative. So, at t=0.7215 the ball will hit the ground. Time taken by ball to hit the ground is

[tex]t=0.7215-0[/tex]

[tex]t=0.7215[/tex]

Round your answer to the nearest hundredth.

[tex]t\approx 0.72[/tex]

So, the ball will hit the ground after 0.72 seconds.

Therefore, the correct option is A.

Answer:

0.72

Answer:

[tex]y=3x+6[/tex]

Step-by-step explanation:

Equation of the line

The equation of the line in slope-intercept form is:

[tex]y=mx+b[/tex]

Being m the slope and b the y-intercept.

We are given two points for the required line: The x-intercept is -2, thus the point is (-2,0), and the y-intercept b=6 represents the point (0,6).

Since the value of b is 6, we use the first point to find the slope:

[tex]0=m(-2)+6[/tex]

Solving:

m=3

The correct equation of the line is:

[tex]\boxed{y=3x+6}[/tex]

Answer:

  £562.42

Step-by-step explanation:

Payments on a loan of P at rate r for n months can be found from ...

  A = P(r/12)/(1 -(1 +r/12)^-n)

For r = .07 and n = 12, the payments on a £6500 loan will be ...

  A = £6500(.07/12)/(1 -(1 +.07/12)^-12) = £562.42

Andy will pay £562.42 each month.

Answer:

7 quarts

Step-by-step explanation:

We can solve this problem by using the rule of three. As seen in the picture below we need to find the X. We do this by multiplying 161 sq. ft. diagonally by 3 quarts and then dividing by 120 sq. ft. This will give us the number of quarts needed for the kitchen wall. Then we simply repeat the process for the bathroom wall and we are done. Like so ...

[tex]\frac{161 sq. ft. * 3 quarts}{120 sq. ft.} = x[/tex]

[tex]4.025 quarts = x[/tex]

[tex]\frac{119sq. ft. * 3 quarts}{120 sq. ft} = x[/tex]

[tex]2.975 quarts = x[/tex]

Therefore we need 4.025 quarts for the kitchen wall and 2.975 quarts for the bathroom wall ... making that a total of 7 quarts.

Answer:

B

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{35}{5}[/tex] = [tex]\frac{42}{x}[/tex] ( cross- multiply )

35x = 210 ( divide both sides by 35 )

x = 6 → B

Answer:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Step-by-step explanation:

Given: A line is drawn between points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]

To find: distance between the two points

Solution:

A coordinate plane is a two-dimensional plane formed by the intersection of a  y-axis and x-axis. x-axis and y-axis are perpendicular lines that intersect each other at the origin.

Let d denotes distance between the two points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]

Use the formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The distance between the two points show on the coordinate plane is D = √[(x₂-x₁)²+(y₂-y₁)²]. Therefore, the correct answer is option C.

The given coordinate points are (x₁, y₁) and (x₂, y₂).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.

On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is

Distance = √[(x₂-x₁)²+(y₂-y₁)²].

Therefore, the correct answer is option C.

Answer: It's 50

Step-by-step explanation:

3.4 divided by 6.8 is 0.5 and 18-16 (the exponents) is 2. since ur dividing your subtracting the exponents. so then u get 0.5*10^2 but it cant be lower than 1 so u move the decimal in 0.5 one space to the right which then leads you to get 5*10^1 or 5*10 which is 50.

the missing term is 5

Hi there !

12x² - 75 =

= 3(4x² - 25)

use formula a² - b² = (a - b)(a + b)

= 3(2x - 5)(2x + 5)

= 3(2x + 5)(2x - 5)

the missing term is 5

Answer:

$49.50

Step-by-step explanation:

Answer:

m = 0, y = -6

Step-by-step explanation:

using point slope form :

[tex]y - y_{1} = m(x - x_{1})[/tex]

y-y1=m(x-x1) ; initial point (x1,y1) = (4,-6), final point (x,y) = (7,-6).

one substituted, it should look like this:

-6--6 = m(7-4),

-6+6= m(7-4)

0 = m(7-4)

0 = 3m

0/3 = 3/3m

0 = m

m = 0/3 = 0
