Alexa can bike home from school an hour and a half faster than she can walk home. her biking speed is 9 miles per hour faster than her walking speed. her school is 6 miles from her home. write an equation that can be used to find her walking speed, w.

Answer:

The rule is "Subtract 9"

n = 11

Step-by-step explanation:

To find the rule you have to find what's common with all of them. This requires a little bit of testing.

THINK

Do I divide by 10? No because it doesn't work for all of them.

Do I divide by 4? No because it doesn't work for all of them.

Do I subtract by 9? Yes because it works for all of them.

Rules can be a lot of things. Subtraction, multipilcation, division, addition, or with variables.

Answer:

See below.

Step-by-step explanation:

∠G = 80°

TY = 15

∠G = ∠T (similar triangles)

OY : UN = 3: 4

TY : GN = x : 20 = 3 : 4

⇒ x/20 = 3/4

⇒ x = 15

Answer:

The third one x+49+28=180

Step-by-step explanation:

We can say that the angle between the 29° angle and the 49° angle is equal to x, since they are vertically opposite angles.

The sum of 28+49+x is equal to a supplement angle which is a straight line essentially

We can then say x+28+49=180

If you want to calculate x,

x=180-28-49

x=103

Answer:

each child will get 2 1/3 quarts of juice each

Step-by-step explanation:

Question 7

Total amount of juice = 1 4/6 + 2 + 2 + 2 + 2 2/6 + 2 5/6 + 2 5/6 + 3 = 56/3

Number of children = 8

If the juice was shared equally:  56/3 ÷ 8 = 7/3 = 2 1/3 each

Therefore, each child will get 2 1/3 quarts of juice each

Answer:

Any value you choose for x will make the equation a TRUE statement. This type of equation is called an identity, and the solution set is all real numbers.

An identity is an equation that, regardless of the values used, is always true.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

An identity is an equation that, regardless of the values used, is always true.

For the linear equation y = mx + c, all the values of the variable x are real numbers because the quadratic function is defined.

Answer:1m-7<0

Step-by-step explanation:

4m-3m-3-4

1m-7<0

The solution to the inequality 4m - 3(m + 1) - 4 < 0 is m < 7.

We have,

To solve the inequality 4m - 3(m + 1) - 4 < 0, we can follow these steps:

Simplify the expression inside the parentheses:

4m - 3(m + 1) - 4 = 4m - 3m - 3 - 4 = m - 7.

Rewrite the inequality:

m - 7 < 0.

Add 7 to both sides of the inequality to isolate the variable:

m - 7 + 7 < 0 + 7,

m < 7.

Therefore,

The solution to the inequality 4m - 3(m + 1) - 4 < 0 is m < 7.

[tex] \frac{12}{14} \div \frac{7}{6} [/tex]

[tex] \frac{12}{14} \times \frac{6}{7} [/tex]

[tex] \frac{6}{7} \times \frac{6}{7} [/tex]

[tex] \frac{36}{49} [/tex]

The result of 12/14 divided by 7/6 as a fraction is 36/49.

To divide the fraction 12/14 by 7/6, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction 'a/b' is 'b/a'.

So, the division can be written as:

(12/14) ÷ (7/6) = (12/14) * (6/7)

Now, we can simplify the multiplication:

(12/14) * (6/7) = (12 * 6) / (14 * 7)

Calculate the numerator and denominator:

72 / 98

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 2:

72 ÷ 2 / 98 ÷ 2 = 36 / 49

Therefore, the result of 12/14 divided by 7/6 as a fraction is 36/49.

Step-by-step explanation:

John's portion can be represented as 2x and Kim's portion can be represented as 6x as this will still be in a ratio of 2:6.  The total of 2x and 6x equals 2400 so 8x = 2400 so divide both sides by 8 to find that x = 300.  Kim's portion is 6x so 6(300) equals 1800.

Answer: 71.6°< F< 86°

Step-by-step explanation:

Let  C=  temperature in tropical rain forest (in  Celsius)

Given: In a tropical rain forest, the temperature ranges from 22° C to 30° C.

The compound inequality that represents the possible temperatures of a tropical rain forest.

22° < C < 30°

Since, [tex]\dfrac95C=F-32\Rightarrow\ F=\dfrac95C+32[/tex]

Also, At C= 22 , [tex]F= \dfrac95(22)+32=71.6[/tex]

At C= 30 , [tex]F= \dfrac95(30)+32=86[/tex]

Hence, the compound inequality that represents the possible temperatures (in degrees Fahrenheit) of a tropical rain forest.

71.6°< F< 86°

Answer:

71.6 <= T =<86

Step-by-step explanation:  

celsius= 22 a.k.a Fahrenheit= 71.6

celsius= 30 a.k.a Fahrenheit= 86

so the degree ranges from 71.6 or more to 86 or less so

Use T for tempature this is an and problem so you write it like this

71.6 <= T =<86

in english this is saying that T ( tempature ) is more or equal to 71.6 and is less or equal to 86.

Answer:

His speed is 66.25 miles/hour

Step-by-step explanation:

The rule of the constant speed is:

Speed = Distance ÷ Time

∵ Karim starts his journey at 11:00 a.m. and finishes at 3:00 p.m.

→ Count the hours from 11: 00 a.m. to 3:00 p.m.

∴ He takes 4 hours ⇒ (3 + 12 - 11)

∴ T = 4 hours

∵ The mileage reader is 66,750 miles at 11:00 a.m.

∵ The mileage reader is 67,015 miles at 3:00 p.m.

→ The distance that Karim is driving = the difference between them

∴ The distance that karim is driving = 67,015 - 66,750

∴ D = 265 miles

→ Substitute the values of D and T in the rule above

∵ S = 265 ÷ 4

∴ S = 66.25 miles/hour

∴ His speed is 66.25 miles/hour
