Answer:

1 1/5 km/h

Step-by-step explanation:

1x6=6

Take the numerator and multiply denominator

Answer:

Step-by-step explanation:

Velocity is distance divided by time.

v=(km/5)/(hr/6)

v=(km/5)(6/hr)

v=(6/5)(km/hr)

v=1.2 km/hr

Answer:

He earns $4 for a load of laundry and $2 for a load of dishes.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is how much he earns for a load of laundry.

y is how much he earns for a load of dishes.

Last week, he did 1 load of laundry and 3 loads of dishes, and his parents paid him $10.

This means that:

[tex]x + 3y = 10[/tex]

[tex]x = 10 - 3y[/tex]

The week before, he finished 1 load of laundry and 7 loads of dishes, earning a total of $18.

This means that [tex]x + 7y = 18[/tex]

Since [tex]x = 10 - 3y[/tex]

[tex]10 - 3y + 7y = 18[/tex]

[tex]4y = 8[/tex]

[tex]y = \frac{8}{4}[/tex]

[tex]y = 2[/tex]

[tex]x = 10 - 3y = 10 - 3*2 = 10 - 6 = 4[/tex]

He earns $4 for a load of laundry and $2 for a load of dishes.

Answer:

x = 3

Step-by-step explanation:

You can use cross multiply.

8x = 6 x 4

8x = 24

x = 3

Answer:

x = 3

Step-by-step explanation:

Multiply x by 8 to get 8x

Multiply 6 by 4 to get 24

Place 8x and 24 into an equation to get 8x = 24

Divide 8x and 24 by 8

The 8 from 8x is canceled out, leaving the answer:

x = 3

Step-by-step explanation:

Answer:

B = 6(4 + 5)

Step-by-step explanation:

GCF = The greatest common factor, example: GCF of 12 and 16 = 12 is divisible by all of these numbers. The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

Distributive property = allows us to multiply the number by a group of numbers, which are added together. The distributive property is given by: a(b+c) = ab + ac

The Greatest Common Factor of 24 and 30 is 6 because it is the largest number they have together (24 = 6*4 and 30 = 6*5)

24 divided by 6 = 4

30 divided by 6 = 5

This fits B the most: 6(4 + 5)

The answer is B, I hope this helps!

Go to desmos dot com it's a life saver. Type the equation into the thing and it shows up

Or, the equation would be y=-1/3x+3. 3 is your y intercept, and you have a slope of -1/3 (down one, to the right three)

Answer:

[tex]\frac{40}{27}[/tex]

Step-by-step explanation:

We need to evaluate the sum of the following finite geometric series.

We need to define r and [tex]a_{n}[/tex]

[tex]r = 1/3[/tex]

[tex]a_{n} =(\frac{1}{3} )^{n-1}[/tex]

Follow the geometric sequence sum formula and substitute :

[tex]1*\frac{1-(\frac{1}{3})^4 }{1-\frac{1}{3} }[/tex]

Simplify :

[tex]1 * \frac{3*\frac{80}{81} }{2}[/tex]

Get rid of the 1 :

[tex]\frac{3*\frac{80}{81} }{2}[/tex]

Multiply the numerators :

[tex]\frac{\frac{80}{27} }{2}[/tex]

Move the denominator of the fraction in the numerator and move it to the denominator of the whole fraction :

[tex]\frac{80}{27*2}[/tex]

Multiply the denominators :

[tex]\frac{80}{54}[/tex]

Simplify  by dividing both the numerator and denominator by 2 :

[tex]\frac{40}{27}[/tex]

Answer:

Step-by-step explanation

$3.75x5=18.75

18.75+10=$28.75

Step-by-step explanation:

So he starts with 10. That would be our y-intercept. That means that 3.75 is the slope because he saves that amount of money each week. So the equation would be y = 3.75x + 10.

The x represents the number of weeks (5), so we will plug that into the equation (y = 3.75(5) + 10).

Multiply 5 and 3.75 to get 18.75

Add 10 to get 28.75

Answer:

(11,2)

Step-by-step explanation:

(8+3,11-9)

(11,2)

After the translations the point locates at (2, 5) and it is in first quadrant.

A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.

Given that, in the first quadrant, you start at (8, 11) and move 3 units right and 9 units down

The point moves 3 units right is (8+3, 11+3)

= (11, 14)

The point moves 9 units down is

(11-9, 14-9)

= (2, 5)

Therefore, after the translations the point locates at (2, 5).
