First we want to calculate exactly how much money Bernice sells on a daily basis, so we can determine how many days it'll take to earn 2,430 dollars. We can do this by multiplying the amount of shells she sells every day by the amount she sells them for. So 135 sea shells multiplied by 3 dollars.
<u>135 * 3</u>
This comes up to 405 dollars every day, quite a significant amount considering she's selling shells. Now, divide 2,430 dollars by 405 dollars. This will give us the final result.
<u>2,430 / 405</u>
It will take Bernice exactly 6 days to earn 2,430 dollars.
To solve for y, you do not get a value as there are no values in the equation. You can however still solve, as long as you make the equation "y =". To do this, you need to get y by itself, and we can see that it is being multiplied by r. To move the r onto the other side, we therefore have to divide by r on both sides. This leaves us with y = Z/r, which is your answer.
I hope this helps!
Answer:
true
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
L = 3x + 2
W = 2x - 3
Area = L * W
Area = (3x + 2)(2x - 3) Use FOIL to expand.
F (First): 3x * 2x = 6x^2
O (Outside): (3x)( - 3) = - 9x
I (Inside): 2 * 2x = 4x
L (Last): 2*(-3) = - 6
Answer = F + O + I + L
Answer = 6x^2 - 9x + 4x - 6 Reduce
Answer = 6x^2 - 5x - 6
Answer: B
