Answer: -12.5
Step-by-step explanation:
x(2y-3) and x=2.5 and y=-1
so you fix in the figures so it will turn to
2.5(-2-3)
so then you open the brackets with 2.5
-5-7.5
Answer: -12.5
The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.
Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:

2. according to the Pyphagorean theorem (in the smallest triangle):

answer: y=√55.
Answer:
The 64 ounce jug of milk costs $0.010 more per ounce than the 128 ounce jug of milk/
Step-by-step explanation:
3.20/128=$0.025 per ounce jug of milk
2.24/64=$0.035 per ounce jug of milk
0.035 - 0.025 = .010
Answer:
The value of y is -5
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
If x and y satisfy both equations, then (x,y) is the solution of the system of equations
Using a graphing tool
Remember that
The solution of the systems of equations is the intersection point both graphs
The intersection point is (2,-5)
therefore
The solution of the system of equations is the point (2,-5)
The value of y is -5
