If Kim's age is twice of her sister. When you add Kim's age to her sister age, you get 36. How old is each sister? A) Write an equation that represents the situation. Explain any variable used. B)solve the equation from part (a)show your work. State your solution as a complete sentence. Thank you
Answer:
Let's kim's sisters age be 2x and kim's age be x.
★ When we add kim's age to her sister age, they equals to 36.
So, the equation becomes -
[tex] \\ \implies \sf \: x + 2x = 36 \\ \\ \\ \implies \sf \: 3x = 36 \\ \\ \\ \sf \underline{Now, \: \: solve \: \: for \: x \: \: - } \\ \\ \\ \implies\sf \: x = \frac{36}{3} \\ \\ \\ \implies \large{ \boxed{ \sf{ x = 12}}} \\ [/tex]
Kim's sisters age = 12 years.Kim's age = 2x = 2 × 12 = 24 years.Find the midpoint of (-4,6) and (10,-10)

m=3,-8
A car covers a distance of 14.75km in 20 minutes. In how many seconds, will it cover a distance of 73.75km
Answer:
6000 seconds.
Step-by-step explanation:
Given:
A car covers a distance of 14.75km in 20 minutes.
find:
In how many seconds, will it cover a distance of 73.75km
solution:
the idea is ratio and proportion to get the time based on 73.75 km from 14.75km./20min. in seconds.
14.75 km. = 73.75 km --------> cross multiply
20 min. t
14.75 (t) = 73.75 (20)
14.75 (t) = 1475
t = 1475
14.75
t = 100 min. -----------> convert min to seconds.
100 min. x 60 secs. = 6000 seconds
1 min.
therefore,
the time in seconds to travel a distance of 73.75 km is 6000 seconds.

Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many
baseball cards remain in Ryan's collection?
Answer:
117
Step-by-step explanation:
216/3=72
216-72=144
144-26=117
Answer: 117
Step-by-step explanation:
First you do 216 divide by 3 to know how many cards he gave his brother. So 216/3 is equal to 72. Then you add 72 to 27 to know the total amount of cards he loses, which is 99. Now you do 216-99 to get 117.
117 baseball cards remain in Ryan's collection.
Write an absolute value equation that has the solutions x= -6 and x = 10.
The equation is blank
HERES THE EXAMPLE: If | x | = 3, we know that x may be either +3 or - 3,
since both are 3 units from the origin.
Notice that the answer is "OR", since x cannot be both -3 and +3 at the same time.
ANSWER: so the x=-6 would be would just be six units -6 to 0 would be 6
the x=10 would be -10
600 ÷ 300 hey answers
Answer:
2
Step-by-step explanation:
I hope this helps you :)
Answer:
2
Step-by-step explanation:
Anything divided by 2 is half of itself. So 600 ÷ 300 would technically be 300. But in division we count the amount of times a number can go into the other number. So 600 divided by 300 is 2.

Complete Question
The complete question is shown on the first uploaded image
Answer:
6a
[tex]V(3) = 113.112[/tex]
6b
[tex]V(\frac{3}{2}) = 14.139 [/tex]
6c
[tex]V(2r) = 33.514r^3[/tex]
7a
[tex] h(5) = 0 [/tex]
7b
[tex] h(t) = -5.76 [/tex]
7c
[tex] h(x+5) = x(x+5)[/tex]
Step-by-step explanation:
Considering the question 6
The function given is [tex]V(r) = \frac{4}{3} \pi r^3[/tex]
For V(3) we have
[tex]V(3) = \frac{4}{3} \pi 3^3[/tex]
[tex]V(3) = \frac{4}{3} * 3.142 * 3^3[/tex]
[tex]V(3) = 113.112[/tex]
For [tex]V(\frac{3}{2})[/tex]
[tex]V(\frac{3}{2}) = \frac{4}{3} * \pi * (\frac{3}{2})^3 [/tex]
[tex]V(\frac{3}{2}) = \frac{4}{3} * 3.142 * (\frac{3}{2})^3 [/tex]
[tex]V(\frac{3}{2}) = 14.139 [/tex]
For V(2r)
[tex]V(2r) = \frac{4}{3} \pi (2r)^3[/tex]
[tex]V(2r) = \frac{4}{3} * 3.142*8r^3[/tex]
[tex]V(2r) = 33.514r^3[/tex]
Considering the question 7
The function given is [tex] h(t) = t^2 - 5t [/tex]
For h(5)
[tex] h(5) = 5^2 - 5(5) [/tex]
[tex] h(5) = 0 [/tex]
For h(1.8)
[tex] h(t) = 1.8^2 - 5(1.8) [/tex]
[tex] h(t) = -5.76 [/tex]
For h(x+ 5)
[tex] h(x+5) = (x+5)^2 - 5(x+5) [/tex]
[tex] h(x+5) = x^2 + 25+10x-5x-25[/tex]
[tex] h(x+5) = x(x+5)[/tex]
In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. What are the odds of a yellow marble being selected on the first draw? CHOICES ------> ( 4:2 1:5. 3:3. 2:4) SOS
Answer:
1:3
Step-by-step explanation:
To find the probability of selecting a certain type of item from a collection, simply divide the number of items of that type by the total number of items.
There are 3 + 2 + 1 = 6 marbles in total. There are 2 yellow marbles, so the probability of choosing a yellow marble on the first draw is 2/6. This can be further simplified to 1:3.
Answer:
i would say 2:4
Step-by-step explanation:
think about them as basketball teams
The yellow team has two players
the mix team has 4 players
so the game is 2 players on 4 players
Assuming the angle below is drawn to scale, which of the following could be the measure of 2XYZ? A. 120° B. 90 C. 180° O D. 30°
Answer:
Option (A)
Step-by-step explanation:
Given angle in the picture is neither a right angle (equal to 90°) nor obtuse angle (greater than 90°).
It's an acute angle which measures less than 90°.
Therefore, possible measure of the given acute ∠XYZ = 30°
Option (A) will be the answer.

If 4 tickets to a show cost$9.00, find the cost of 14 tickets.
Answer:
Step-by-step explanation:
Answer:
31.50 for 14 tickets
Step-by-step explanation:
We can use ratios to solve
4 tickets 14 tickets
-------------- = --------------------
9 dollars x dollars
Using cross products
4x = 9*14
4x =126
Divide each side by 4
4x/4 = 126/4
x =31.50
3x - y = 2
and
2x + y = 4
[tex]\frac{3}{1}[/tex]Answer:
Step-by-step explanation:
3x-y = 2
2x+y =4
put them into slope intercept form
y=3x-2
y=-2x+4
Now, you can either graph it or use substitution
3x-2 = -2x+4
+2x +2x
5x -2 = 4
+2 +2
5x = 6
5x/5 = 6/5
x = 6/5
3x -2 = y
3(6/5) -2 = y
3 x 6 / 1 x 5 = 18/5
3 3/5 -2 = 1 3/5
Let me know if it's wrong.

-5 ≤ 1 - 2x < 9
Let's first break this down into two different inequalities.
1 - 2x ≥ -5
Subtract 1 from both sides.
-2x ≥ -6
Divide both sides by -2
x ≤ 3
Now, let's do the second inequality.
1 - 2x < 9
Subtract 1 from both sides.
-2x < 8
Divide both sides by -2
x > 4
let's combine each inequality to get our reduced compound inequality.
-4 < x ≤ 3
To plot this, put a hollow point at -4. A hollow point looks something like the letter o.
And put the second point at 3. This time, fill in the point so it looks whole.
Now, connect your points.
It should look something like this:

In 2014, a toy store sold 12,823 stuffed animals. In 2015, the toy store sold 24,290 more stuffed animals than it did in 2014. The toy store sold the same number of stuffed animals in 2016 as it did in 2015. How many stuffed animals did the toy store sell in 2014, 2015, and 2016 combined?
Answer:
i say 24,890
Step-by-step explanation:
The number of stuffed animals did the toy store sell in 2014, 2015, and 2016 combined is 87,049.
Given that, in 2014, a toy store sold 12,823 stuffed animals. In 2015, the toy store sold 24,290 more stuffed animals than it did in 2014.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of stuffed animals did the toy store sell in 2014, 2015, and 2016 combined be x.
Number of toys sold in 2014 = 12,823
Number of toys sold in 2015 = 12,823 + 24,290
=37,113
The toy store sold the same number of stuffed animals in 2016 as it did in 2015. That is, 37,113.
Now, x = Number of toys sold in 2014 + Number of toys sold in 2015 + Number of toys sold in 2016
=12,823+37,113+37,113
=87,049
Therefore, the number of stuffed animals did the toy store sell in 2014, 2015, and 2016 combined is 87,049.
