Explanation:
Let the price of a toy car be a.
Let the price of a yo-yo be b.
You can solve this problem using simultaneous linear equation.
From the question above, you can form 2 separate equations.
For the first equation,
3 toy cars sold next day = 3a
12 yo-yos sold next day = 12b
Total price = $102
The second equation would be
[tex]3a + 12b = 102[/tex]
Now, we are not finished yet. Make sure that for the first equation, only one of the unknown (a or b) stays on the left-hand side of the equation. Let's try a.
[tex]3a + 12b = 102 \\ 3a = 102 - 12b \\ a = \frac{102 - 12b}{3} \\ a = 34 - 4b[/tex]
Lets move on with finding the second equation.
15 toy cars sold = 15a
20 yo-yos sold = 20b
Total price = $190
So, the second equation would be:
[tex]15a + 20b = 190[/tex]
You don't have to move any unknowns to the other side for the second equation.
Now, take equation 1 and substitute into equation 2. This can be done by replacing the value of a in the second equation with the value of a on the right hand-side of the first equation. For example:
[tex]15a + 20b = 190 \\ 15(34 - 4b) + 20b = 190 \\ 510 - 60b + 20b = 190 \\ 510 - 190 = 60b - 20b \\ 320 = 40b \\ b = \frac{320}{40} \\ = 8[/tex]
Hence, the price of a yo-yo, b, is $8. The price of a toy car is :
[tex]a = 34 - 4b \\ = 34 - 4(8) \\ = 2[/tex]
$2.
The cost of one toy car is $2.
What is a simultaneous linear equation?Two or more linear equations that all contain the same unknown variables are called a system of simultaneous linear equations. Solving such a system means finding values for the unknown variables which satisfy all the equations at the same time.
Let the price of a toy car be [tex]a[/tex].
Let the price of a Yo-Yo be [tex]b[/tex].
For the first equation,
3 toy cars sold the next day = 3[tex]a[/tex]
12 yo-yos sold the next day = 12[tex]b[/tex]
Total price = $102
The first equation would be
3[tex]a[/tex]+12[tex]b[/tex]=102
Finding the second equation.
15 toy cars sold = 15[tex]a[/tex]
20 yo-yos sold = 20[tex]b[/tex]
Total price = $190
So, the second equation would be:
15[tex]a[/tex]+20[tex]b[/tex]=$190
With the help of these equations, we can find the price of a toy car.

What do you think are the disadvantages of these methods of direct democracy
Answer:
Direct democracy has never worked
Explanation:
Disadvantages include: rule of the mob mass, promotes manipulation and corruption, instability, and slows the country's progress among other crucial disadvantages.
Answer:
Direct democracy can often take a long time to initiate. Even a good idea that could potentially have a large amount of support may take a long time to gain enough traction to become an official proposal.
Also, the average citizen may not be fully aware of the facts surrounding an issue or might go to the polls to vote without knowing anything about the proposals on the ballot. This means that uninformed citizens may not be making the best decision for their communities.
Direct initiatives and referenda present another potential problem in that this model provides no safeguard for minority rights. A majority of the people might vote yes on a proposal, but this doesn’t guarantee that it is a good idea for everyone who might be affected by the proposal.

Can someone help me with this question and explain me well too. *AND please don't just write whatever because that is not helpful for me or then i'll REPORT you* QUESTION: What best describes the result of the Missouri Compromise? A= It solved the slavery issue in America. B= It led to the ending of slavery in America C= It banned slavery in all new territories D= It temporarily calmed the slavery issue in America.
Answer:
Your answer will be D.
Explanation:
The Compromise of 1850 acted as a temporary truce on the issue of slavery. The reason why is the Compromise worked out the issue of slavery in the North and South. The South is known to be "Slave States". But at this time everyone had slaves but majority of the slaves were located in the South. (So when you hear about freed slaves at the end of the Civil War most of them have moved to either Kansas or Missouri.) So becuase of the Missouri Compromise, Missouri has now freed its slaves along with slaves in Maine. It also learned how to deal with the spread of slavery into western territories. The compromise divided the lands of the Louisiana Purchase into two parts. Slavery would be allowed south of latitude 36 degrees 30'. So in conclusion this Compromise helped limit the amount of slaves in the south.

Which of these was a factor that led to the development of plantation agriculture in the South?
Answer:
Hello. You did not put the answer options, but I can help you by saying that the factors that led to the development of plantation agriculture in the South were the climate, the existence of plains and the fertile soil.
Explanation:
Most of the southern United States has soils with high fertility and with low prevalence of low plains and lands. In addition, the south has hot summers and dwarf winters, which means that plantation agriculture is favored to a great extent. This allowed the USA to become a strong agricultural power, in addition to allowing the southern states to be responsible for the consumption of food in the country.
In this case, in addition to livestock, the southern United States had a good establishment of crops such as wheat, barley and rye.
