Answer:
The discount percentage on the coat = 30%
Step-by-step explanation:
Here, the original cost of the coat = $75
The sale price of the same coat = $52.50
Now, here DISCOUNT = ORIGINAL PRICE - SALE PRICE
= $75 - $52.50 = $22.50
⇒The discount amount on the coat = $22.50
⇒The discount percentage on the coat = 30%
A.2x2x5x7
B.4x5x7
C.2x3x5x7
D.5x5x7
Answer:
A
Step-by-step explanation:
This one is best done by doing a pre factor.
140 = 14 * 10 Now all you need do is factor those two numbers.
140 = 7*2 * 5 * 2
Rearranging this you get 2 * 2 * 5 *7
A
B. $21.87
C. $97.20
D. $218.70
Answer:
Option C.
Step-by-step explanation:
Let x be the total amount of the dinner bill.
It is given that Mason gave the waiter a $14.58 tip, which was 15 percent of the dinner bill.
Multiply both sides by 100.
Divide both sides by 15.
The amount of the dinner bill before he added the tip is $97.20. Therefore, the correct option is C.
y= 2x - 5
The solution to the system of equations is x = 5 and y = 5. The coordinates (5, 5) represent the point where the two lines intersect in the xy-plane, and it is the unique solution to this system of linear equations.
Given that the system of equations:
y = 3x - 10 (1)
y = 2x - 5 (2)
Since both equations are set equal to y, equate the right-hand sides of the equations since they represent the same value of y:
3x - 10 = 2x - 5
Now, let's solve for x:
3x - 2x = -5 + 10
x = 5
Now, found the value of x, substitute it back into either of the original equations to find the corresponding value of y.
Let's use the equation (1):
y = 3x - 10
y = 3(5) - 10
y = 15 - 10
y = 5
Hence, the values of x and y are 5 and 5. The system of equations have unique solution.

Complete question:
Solve the system of equations for x and y:
If you're looking for a solution for both equations and had a choice between the 3 ways of solving it, I would choose substitution for this problem. So..
2x-5=3x-10
Move like terms to their own sides.
Take 2x away from both sides, and add 10 to both sides. That should leave you with
5=x
Now that you have the x, plug it into the equation that works best for you to solve.
That should be y=2(5)-5
y=10-5
y=5
(5,5) is your solution.
B.225 cubic yds
C.450 cubic yds
D.500 cubic yds
Answer:
C. 450 yd^3
Step-by-step explanation:
V... volume of a prism
a = 20 yd
b = 5 yd
c = 9 yd
Vw... Volume of water
Vw = V/2
Vw = (abc)/2
Vw = 900yd^3/2
Vw = 450yd^3
