John and kim shared $2400 dollars in the ratio 2:6.What is kim's share ?
Answer:
$1800
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.
what describes an equation that has a solution set of "all real numbers"
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.
What is the solution to the equation?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.

Karim is driving his car at a constant speed. At 11:00 A.M., the mileage reader is 66,750 miles. At 3:00 P.M., the mileage reader is 67,015 miles.
What is his speed in miles per
hour? Explain.
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

Put the steps in correct order for the equation Solve 3(2x−7)+5=−19
Answer:
6x-21+5 = -19 Distribute
6x-16 = -19 Combine like terms
6x = -3 Add
x = -1/2 Division
Answer: x=-1/2 in decimal form -0.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*(2*x-7)+5-(-19)=0
3 • (2x - 7) + 5) - -19 = 0
Pull out like factors :
6x + 3 = 3 • (2x + 1)
Solve : 2x+1 = 0
Subtract 1 from both sides of the equation :
2x = -1
Divide both sides of the equation by 2:
x = -1/2 = -0.500
4m – 3(m + 1) – 4 < 0
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.

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

Tiana placed two orders for flowers and bushes. The first order was for 24 flowers and 6 bushes. The total cost of the first order was $144. The second order was for 18 flowers and 3 bushes. The total cost of the second order was $90. What is the cost of each plant?
Answer:
Step-by-step explanation:
24x + 6y = 144.
18x + 3y = 90.
Divide the (24x + 6y = 144) by 3.
8x + 3y = 48.
18x + 3y = 90.
Cancel the 3y.
8-18x = -10x.
48-90 = -42.
-10x = -42.
x = 4.2
8(4.2) + 3y = 48.
33.6 + 3y = 48.
Cancel out the whole number.
3y = 14.4
y = 4.2
The cost of a flower is $3 and a bush is $12.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.
Given:
Tiana placed two orders for flowers and bushes.
The first order was for 24 flowers and 6 bushes.
The total cost of the first order was $144.
The second order was for 18 flowers and 3 bushes.
The total cost of the second order was $90.
Let x be the number of flowers and y be the number of bushes.
So, we have a system of equations,
24x + 6y = 144
18x + 3y = 90
Simplifying,
4x + y = 24
6x + y = 30
Subtracting the equations,
we get,
2x = 6
x = 3, and y = 12
Therefore, the solution is x = 3, and y = 12.

In a tropical rain forest, the temperature ranges from 22 degrees Celsius to 30 degrees Celsius. Write and solve a compound inequality that represents the possible temperatures (in degrees Fahrenheit) of a tropical rain forest.
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.
