You must evaluate each of these options one by one:
A. A $55 jersey with 5% (.05) tax would equal 55 x (1+.05). This equation basically adds on 5% to the original $55. This equals $57.75
B. You can calculate this similarly to above, because it is asking you to add 10% on to the original $57. This would be 57 x (1+.10) = $62.70
C. This is clearly not an option because the original price of the jersey is already more than what Dave has.
D. This is asking you to deduct 25% of the original cost off of $85. You find this similarly to above, but this time you deduct 25% from the 1 --> 85 x (1 - 0.25) = $63.75
So you can see that Dave can only afford option A. Does that make sense?
Pretty sure is 44km. At least i think so
Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
= 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
= 2 * 4 inches
= 8 inches
Now
The Area of the rectangle = Width * Length
= 4 * 8 inches^2
= 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.
Answer:
Step-by-step explanation:slope is 12
Answer:
x = 10, y = 30
Step-by-step explanation:
Since this already has a y-value, which is 3x, we will use substitution.
3x + 7x = 10
10x = 10
x = 10
Now that we know x, we can figure out what y is.
y = 3(10)
y = 30
