Amy can ride her bike 4 miles in 30 minutes. At her current rate, what is the difference, in miles, Amy can ride her bike in 12 minutes?​

Answer:

a.) 1/2n 4=3−5/n b.) 1/2(n 4)=5/n−3 c.) 1/2(n 4)=3−5/n d.) 1/2n 4=5/n−3

Let's assume the number be n.

So, sum of number and four can be written as n+4.

Now one-half of n+4 will be .

Quotient of five and the number can be written as .

Now three less \frac{5}{n} can be written as \frac{5}{n} -3.

So, one-half the sum of a number and four is three less than the quotient of five and the number can be converted into equation as follows:

So, b is the correct choice.

Answer:

A. addition property of equality

Step-by-step explanation:

To make x stand alone, "5" was added to both sides of the equation. The property that is applied here is the addition property of equality.

Adding "5" to both sides of the equation makes the equation balanced.

The answer is: A. addition property of equality

The ratio of corresponding sides is same for all the sides for similar triangles. The value [tex]x[/tex] is 17.5 units and value of [tex]y[/tex] is 19.2 units.

Two polygons are said to be similar or congruent pentagon-

Given information-

In the given figure,

[tex]\Delta ABC\cong \Delta AVW[/tex]

As for the similar triangle the ratios of corresponding sides is same for all the sides. Hence,

[tex]\dfrac{AB}{AV} =\dfrac{BC}{VW} =\dfrac{AC}{AW}[/tex]

Take two ratios to find [tex]x[/tex],

[tex]\dfrac{BC}{VW} =\dfrac{AC}{AW}[/tex]

Put the values,

[tex]\dfrac{16}{10} =\dfrac{28}{x}\\16x=280\\x=\dfrac{280}{16} \\x=17.5[/tex]

Take another two ratios to find [tex]y[/tex],

[tex]\dfrac{BC}{VW} =\dfrac{AB}{AV}[/tex]

Put the values,

[tex]\dfrac{16}{10} =\dfrac{y}{12}\\16\times12=10y\\y=\dfrac{192}{10} \\y=19.2[/tex]

Hence, the value [tex]x[/tex] is 17.5 units and value of [tex]y[/tex] is 19.2 units.

Answer:

Number of catfish = 28

Step-by-step explanation:

Let the number of catfish = c

Number of angle fish = c + 6

Number of guppies = 4*(c + 6) = 4c + 4*6 = 4c + 24

Total fishes = 198

c + c + 6 + 4c + 24 = 198           {Combine like terms}

c + c +4c + 6 + 24 = 198

                6c + 30 = 198              {Subtract 30 from both sides}

                     6c    = 198 - 30

                     6c   = 168

                       c = 168/6           {Divide both sides by 6}

                       c = 28

Answer:

x = 1.7

Step-by-step explanation:

Given

-½ + 5x = 8

Required

Find x

-½ + 5x = 8

Multiply both sides by 2

-1 + 10x = 16

Collect like terms

10x = 16 + 1

10x = 17

Divide both sides by 10

x = 1.7

Answer:

3 steps

Step-by-step explanation:

FIrst of all, if you think about it, we can just say -3 as 3 ( even though they are not equal, were just counting steps.)

On a number line, negative numbers are on the left of 0 and positive on the right of 0.

So, lets say the middle number is 0 on our number line. -3 is 3 steps to the left. We take 1 step to negative 1, another step to -2, and then a 3rd and final step to -3.

The steps represent how far the number is from 0. FIr example, we have to add 3 to -3 to get to 0, like how we add 7 to 0 to get 7!

Hope this helps!

Answer:

If you start at 0, you would have to take 3 steps back or -3 steps.

The number of steps represent the positive and negative numbers on the number line.
