In Cleo’s class, the number of girls is 3 times the number of boys. There are a total of 28 students in the class. How many boys and girls are in Cleo’s class? Let x = girls and y = boys. Solve the system and write your answer in the form (x,y), using no spaces. If your answer is a fraction, write your answer in decimal form.
Answers
Answer: x + y = 28 and 3x + x = 28
Explanation: x + y = 28 is a pretty straightforward equation stating that the sum of x (number of boys) + the sum of y (number of girls) = 28 total students
3x + x = 28, because the amount of girls is three times the number of boys, I wrote the number of boys (x) multiplied by 3 to represent the population of girls and added an additional x to represent the number of boys
Upon further simplification you will get 4x = 28, which can be divided by 4 on both sides to solve for x, or the number of boys. 28/4 = 7, therefore x = 7.
Next, you plug x back into the original equation to get 7 + y = 28. For the final step, subtract 7 from both sides of the equation which will give you y = 21
The class has 7 boys and 21 girls, for a total population of 28 students.
The solution is : The class has 7 boys and 21 girls, for a total population of 28 students.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
x + y = 28 and 3x + x = 28

x + y = 28 is a pretty straightforward equation stating that the sum of x (number of boys) + the sum of y (number of girls) = 28 total students

Next, you plug x back into the original equation to get 7 + y = 28.
For the final step, subtract 7 from both sides of the equation which will give you y = 21
The class has 7 boys and 21 girls, for a total population of 28 students.

Carlos bought 80 feet of rope for $17.60. He needs 20 more feet. If the unit price is the same how much will he pay for the extra 20 feet of rope? Show each step of your solution and explain your reasoning.
Answers
Answer:
$4.40
Step-by-step explanation:
ok so this is an instance of proportional relationships, in this case we changed one side of this equation, and now we need to figure out how to change the other side the that the change is made on both sides of the (=)
heres what we know
$17.60 = 80ft.
$??.?? = 20ft.
to help us find the change we can divide the first known side with second known side as shown below
80 / 20 = 4
so now we know that 80 was divided by 4 to get 20, so now we can divide the other side by the same amount to get...
$17.60 / 4 = $4.40
so it costs $4.40 for 20 ft. of rope
EXTRA: just because we can, lets figure out what 1 ft of rope costs using the same method as show above (starting with 20 ft)
20 / 1 = 20
$4.40 / 20 = $0.22
so the rate at wich the rope is sold is 22 cents a foot
