Answer:
It's the 2nd one
Step-by-step explanation:
To find the number of yellow marbles, you would do the number of blue marbles plus 6 marbles.
So in this case, let's say n was equal to the number of blue balls, the equation would be n+(n+6)=24.
What if n was equal to the number of yellow balls. The equation would be n+(n-6)=24.
Hope this made sense, let me know if you are still confused.
Answer:
28
Step-by-step explanation:
Let n = 21, and evaluate the expression.






Answer: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x represent the total dollar amount of phone sales that she makes.
Let y represent the the total dollar amount of computer sales that she makes.
Josiah earns a 2% commission on the total dollar amount of all phone sales he makes, and earns a 7% commission on all computer sales. She earned a total of $156 in commission. This means that
0.02x + 0.07y = 156 - - - - - - - - - - -1
Josiah had $300 more in computer sales than in phone sales. This means that
y = 300 + x
$20,000
15% of 100,000$ is 15,000$
10% of the remaining 50,000$ is 5,000$
The area of a rectangle equals length times height. (A=LH)
A=256.5 L=18
Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)
next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.
So, it is 256.5/18 equaling H
256.5 divided by 18 is... 14.25
That means the height is 14.25 an the length is 18.
the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.
So you have two sides that are 14.25 and two that are 18 meters long.
14.25+14.25+18+18 equals the perimeter then.
So the answer would be... 64.5!
