Which system of equations is in standard form?

9514 1404 393

Answer:

  ML = 7.5

Step-by-step explanation:

The parallel lines divide the transversals proportionally.

  ML/LK = JH/HG

  ML/10 = 6/8

  ML = 10(6/8) = 7.5

The length of ML is 7.5.

__

We don't need to solve for x. If ML = x-2, then x=9.5.

Answer:

x=-5

Step-by-step explanation:

25 - 3x = 40

-3x + 25 =40

-3x +25--25=40-25

-3x=15

-3x÷-3=25÷-3

x=-5

Answer:

Vertex angle = 124°

Step-by-step explanation:

m<BAC = m<BCA (base angles of isosceles ∆ are congruent)

7x + 1 = 5x + 9

Collect like terms

7x - 5x = -1 + 9

2x = 8

divide both sides by 2

x = 4

Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)

Plug in the value of x

Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))

Vertex angle = 180 - (29 + 29)

Vertex angle = 124°

Answer:

5.75 days

Step-by-step explanation:

Given data

let the number of days be x and the number and the number of miles be y

so that the cost of the rental will be

c= 38.38x+ 0.14y---------1

we are told that the amount at hand is $270

hence

270=38.38x+ 0.14*(350)

solve for x

270= 38.38x+49

270-49= 38.38x

221= 38.38x

divide both sides by 38.38

x= 221/38.38

x= 5.75 days

Hence the  number of days is 5.75 days

Step-by-step explanation:

(10 - 4)/(4 -1)= 6/3= 2

y - 4 = 2(x - 1)

y - 4 = 2x - 2

y = 2x + 2

Answer:

3/4

Step-by-step explanation:

To find 24/32 in its simplest form, you need to find the biggest common factor.

24: 1, 2, 3, 4, 6, 8, 12, 24

32: 1, 2, 4, 8, 16, 32

For these two numbers, it's 8. Divided 24 and 32 by 8.

Answer:

El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m

Step-by-step explanation:

Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.

En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.

Siendo el área del terreno rectangular 16,200 m², entonces

x*(x÷2)= 16,200 m²

Resolviendo:

x² ÷2= 16,200 m²

x²= 16,200*2 m²

x²= 32,400 m²

x= √32.400 m²

x= 180 m

Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

Answer:

Area of the triangle =(height x base ) /2

A=(17x12)/2

A=102

the area of the triangle is 102

Answer:

a triangle, I'm guessing 20ft and 24 ft on the outsides,

would be:

Equation to get the area of a triangle: (A*B)/2

(20*24)/2=Area

20*24= 480

480/2= 240

area= 240

Answer: 240 ft²

Step-by-step explanation:

1. Multiply the base and the height.

2. Divide the product you get by 2.

=> 20 * 24 = 480

=> 480 / 2 = 240

Answer:

B Barney stops less than a foot from the car.

Step-by-step explanation:

From the information given:

The initial speed of barney [tex]v_o[/tex] = 25 mph

Coefficient of friction [tex]\mu[/tex] = 0.7

Recall that

1 mph = 0.447 m/s

Then

[tex]v_o[/tex] = 25 × 0.447 m/s

[tex]v_o[/tex] = 11.175 m/s

The force of friction acting on the barney is expressed as:

[tex]F = \mu N \\ \\ F = \mu mg[/tex]

[tex]ma = \mu mg[/tex]

[tex]a = \mu g[/tex]

a = 0.7 × 9.8 m/s

a = 6.86 m/s²

Since the force acts in an opposite direction to the motion of Barney, Thus the acceleration must also be negative.

a = -6.86 m/s²

Now;

Suppose Barney stops after traveling a  distance (s), so that the final speed is zero.

Then;

Using the kinematic equation;

[tex]v^2 - v_o^2 = 2as[/tex]

[tex]0 - (11.17)^2 = 2 \times (-6.86) s[/tex]

[tex]-124.76 = -13.72 s[/tex]

[tex]s = \dfrac{124.76}{13.72}[/tex]

s = 9.09 m

Recall that;

1 m = 3.28 ft

So;

s = 9.09 m = 9.09 × 3.28 ft

s = 29.81 ft

∴

The distance traveled by the Barney is 29.81 ft which implies that Barney stops less than a foot from the car.
