If Ryan does a job in 10 hours and with the help of Molly they can do it together in 3 hours, how long would it take Molly to do it alone?

Answer:

9.94

Step-by-step explanation:

y = [tex]\frac{1}{4}[/tex] x - 9

y - 2 = - 4(x - 3)

y = - 4x + 14

- 4x + 14 = [tex]\frac{1}{4}[/tex] x - 9

16x - 56 = - x + 36

17x = 92

x = [tex]\frac{92}{17}[/tex]

y = (-4) [tex]\frac{92}{17}[/tex] + 14 = - [tex]\frac{368}{17}[/tex] + [tex]\frac{238}{17}[/tex] = - [tex]\frac{130}{17}[/tex]

(3, 2) , ( [tex]\frac{92}{17}[/tex] , - [tex]\frac{130}{17}[/tex] )

Answer:

GCF = 45

Explanation:

GCF = 45

LCM is 1350

View Solution

GCF of (225,270) by Euclidean algorithm Method

Sort the numbers into ascending order: 225,270

Take the smallest number (225) as your divisor

Work out the modulo operation of the remaining number(s) and the divisor:

270 mod 225 = 45

Gather the divisor and all of the remainders and sort them in ascending order. Remove any duplicates. Our set is then:

45,225

Take the smallest number (45) as your divisor

Work out the modulo operation of the remaining number(s) and the divisor:

225 mod 45 = 0

Gather the divisor and all of the remainders and sort them in ascending order. Remove any duplicates. Our set is then:

45

As there is only one number left (the divisor), it's the Greatest Common Factor

Therefore the Greatest Common Factor of 225,270 is: 45

Answer:

In a tape diagram, each of the lengths represents a fixed quantity of something.

Let's suppose that each one of these lengths represents a distance d.

We also know that the expert trail is 750 meters longer than the beginner one.

And in the tape diagram, the expert trail has 3 more lengths than the beginner trail, then we must have that the difference in distance must be equivalent with the difference in lengths.

750m = 3*d

d = 750m/3 = 250m

Then each length in the tape diagram represents 250m

With this we can find the length of each trail.

The beginner trail has 1 length, then it is 1*250m = 250 meters long.

The expert trail has 4 lengths, then it is 4*250m = 1000 meters long.

Answer:

-8y+12

Step-by-step explanation:

4(-2y +3)

you can distribute the 4

4 • -2y + 4 • 3

= -8y +12

because they are not like terms, you cannot do anything further.

Answer:

Domain: -2 < x ≤ 3

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Since domain encompasses x values only, we are looking at the x-values of the graph. We see that our x-values span from -2 to 3. However, since x = -2 is a open dot, it is NOT included in the domain. Since x = 3 is a closed dot, it IS included in the domain:

(-2, 3] or -2 < x ≤ 3

Answer:

The answer is 5.4

Step-by-step explanation:

To get this first you convert 2 3/5 into a decimal and that gives you 2.6.Now your equation is or 8+(-2.6) either way if you do both problems then you get 5.4.

Answer:

Carlos manejo 252 kilómetros.

Step-by-step explanation:

Dada la siguiente información:

Tarifa fija= $595

Tarifa varaible= $8.4 por km

Costo total= $2,711.8

Primero, establecemos la formula de costo total:

Costo total= tarifa fija + tarifa variable*número de km

Reemplazamos:

2,711.8 = 595 + 8.4x

2,711.8 - 595 = 8.4x

2,116.8/8.4=x

252= x

Answer:

66 ft

Step-by-step explanation:

It is given that the windows on a building are proportional to size of the building.

Height of each window = 18 in

Width of each window = 11 in

Height of the building = 108 ft

Let the width of the building be x.

Since windows on a building are proportional to size of the building, therefore

On cross multiplication we get

Divide both sides by 18.

Answer:

66 ft

Step-by-step explanation:

What your doing is setting up a proportion that of the windows(18x11) dimensions and the buildings(108xW) dimensions.

So it would be 18/11=108/x

you would cross multiply so you would have 11x108 (1188)= 18x

Divide by 18 so x=66

Answer: [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

if [tex](x_{1},y_{1}), (x_{2},y_{2}),[/tex] slope=[tex]\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]

J(-10, -7) K(-4, 1), so [tex]\frac{1-(-7)}{-4-(-10)} =\frac{8}{6}=\frac{4}{3}[/tex]

Answer: x = 8

because  The upper triangle is an isosceles triangle (the two sides are equal)

=> 5x + 5 = 45°

<=> x = (45 - 5) : 5

<=> x = 40:5 = 8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

5x + 5 + 5x + 5 + 90 = 180, that is

10x + 100 = 180 ( subtract 100 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8
