Hey there! I'm happy to help!

First, let's see how many times 6 minutes fits into 20 minutes.

20/6=3 1/3

So, we are traveling 10 miles 3 1/3 times!

10×3 1/3=33 1/3

This train will travel 33 1/3 miles in 20 minutes.

Have a wonderful day! :D

Answer:

No solution

Step-by-step explanation:

There are no values of  x  that make the equation true.

Answer: No solutions

==========================================

Explanation:

Start things off by subtracting 5 from both sides

|x-1|+5 = 2

|x-1|+5-5 = 2-5

|x-1| = -3

We cannot go any further after this point. The result of any absolute value is never negative. The absolute value represents distance from some number to 0. For example, saying |-7| = 7 means -7 is seven units away from 0 on a number line. Negative distance does not make sense.

So going back to |x-1| = -3 makes no sense as well. There are no numbers we can plug in for x to have |x-1| = -3 be true.

The equation |x-1| = -3 has no solutions, so the original equation doesn't have any solutions either.

Answer:

y = - 9x + 15

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 9x - 2 ← is in slope- intercept form

with slope m = - 9

Parallel lines have equal slopes, thus

y = - 9x + c ← is the partial equation

To find c substitute (2, - 3) into the partial equation

- 3 = - 18 + c ⇒ c = - 3 + 18 = 15

y = - 9x + 15 ← equation of parallel line

Answer: Choice D.  P = i/rt

This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.

======================================

Explanation:

In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.

This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get

i = prt

i = p*(rt)

i/(rt) = p*(rt)/(rt) ... dividing both sides by rt

i/(rt) = p

p = i/(rt)

Answer:

b=(0,3)

Step-by-step explanation:

Answer:

[tex]b = 90w[/tex]

Step-by-step explanation:

Required

Determine the relationship

Represent the workers with w and bricks with b

First, we need to determine the constant of proportionality using:

[tex]b = kw[/tex]

Solve for k

[tex]k = \frac{b}{w}[/tex]

When w = 1; b = 90:

[tex]k = \frac{90}{1}[/tex]

[tex]k = 90[/tex]

When w = 2; k =180

[tex]k = \frac{180}{2}[/tex]

[tex]k = 90[/tex]

Notice that [tex]k = 90[/tex] in both cases;

Substitute 90 for k in [tex]b = kw[/tex]

[tex]b = 90w[/tex]

Hence; the relationship is [tex]b = 90w[/tex]

Answer:

1/2 im pretty sure

Step-by-step explanation:

Answer:

-4

Step-by-step explanation:

We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.

The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.

We have the gradient, so we can put it in the equation:

y = x/2 + c

We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.

3 = 6/2 + c

3 = 3 + c

c = 0

Therefore the equation for our line is y = x/2.

We can now put in the y coordinate we were given to work out the corresponding x coordinate:

-2 = x/2

x = -4

Therefore n is -4.

Answer:

x = -13

Step-by-step explanation:

3(x+1) = 2(x-5)

3x + 3 = 2x - 10

3x - 2x = -10 - 3

x = -13

Answer:

x = -13

Step-by-step explanation:

To solve for x, we will have to get the equation in a form with x by itself on one side and a value on the right side.

3(x + 1) = 2(x - 5)

Distribute the 3 on the left side and the 5 on the right side.

3x + 3 = 2x - 10

Subtract 3 from both sides.

3x = 2x - 13

Subtract 2x from both sides.

x = -13

And now we have the answer of x = -13.

Answer:

Area = 14276

Step-by-step explanation:

Length = 2w-6

Width =w

perimeter = 2w+ 2l =504

2w+2(2w-6)=504

2w+4w-12=504

6w=516

w=86

L=2w-6

L=2(86)-6

L = 172-6

L = 166

Area = L*W

area=86*166

Area = 14276

Answer:

Answer:

His original farm was 333 1/3 acres

He has 66 2/3 acres of his land left

Step-by-step explanation:

Lex

His total farmland = x

1/2 of x = Mr frost

100 acres = Mr slate

Remaining = 1/5x

His total farmland = Mr Frost + Mr slate + remaining farmland

x = 1/2x + 100 + 1/5x

x = 5x+2x/10 + 100

x = 7/10x + 100

x - 7/10x = 100

10x-7x/10 =100

3/10x = 100

Divide both sides by 3/10

x = 100 ÷ 3/10

= 100 × 10/3

= 1,000/3

= 333 1/3 acres

His original farm was 333 1/3 acres

He has 1/5 of his original farm

1/5 × 1000/3

= 1,000 / 15

= 66 10/15

= 66 2/3 acres

He has 66 2/3 acres of his land left

Answer:

p = - 115

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

px - 5y = 60 ( subtract px from both sides )

- 5y = - px + 60 ( divide all terms by - 5 )

y = [tex]\frac{1}{5}[/tex] px - 12 ← in slope- intercept form

with slope m = [tex]\frac{1}{5}[/tex] p , thus

[tex]\frac{1}{5}[/tex] p = - 23 ( multiply both sides by 5 to clear the fraction )

p = - 115

Answer:

x = 3

Step-by-step explanation:

We can write the equation as 16 + x = 19

To solve we can work backwards, I know the opposite of adding is subracting... so 19 - 16 = 3 which means x is equal to 3.

Hope that helps and have a great day!

Hey there!

[tex]16+x=19[/tex]

There is an easy way to solve this question. First, subtract 19 - 16.

[tex]19-16=3[/tex]

Now let's try putting 3 in x to see if it makes sense.

[tex]16+x=19\\16+3=19(ANSWER)[/tex]

It equaled 19. So this is your answer.

Hope this helps!
