The x would equal 6 because if you substitue 6 for x and 2 for y, when you add them, it will be 8. Divide that by 2 and it will result in 4. And if you subtract 2 from 6, your answer will still be 4.
x+y/2
Substitute 6 for x and 2 for y
6+2/2
Add 6 and 2
8/2
Divide
Final Answer: 4
6-2
Subtract
Final Answer: 4
Since both of the answers result in 4, that is what makes x=6 and y=2 true.
You divide 144 by 90: 144/90, and get 1.6, 160% markup, or just 1.6 markup
Answer:
Percentage increase = 269%
Step-by-step explanation:
Price of a DVD last week = $2.87
Price of the same DVD this week = $10.59
Increase in the price of DVD between last week and this week = 10.59 - 2.87
= $7.72
Therefore, percentage increase in the price of DVD = 
= 
= 268.99
= 269%
Answer:
A.Area of the base
Step-by-step explanation:
these is obtained by multiplying the length and width of the base to get the area of the base
Right now that equation is a function of time, h(t), height with respect to time. If the baseball is on the ground, it has no height. In other words, its height = 0. So if we set the equation equal to 0 and solve for t, time, that will tell us the time that the ball had a height of 0. If you plug those numbers into the quadratic formula, which is the best and most efficient way to factor a quadratic, you will get that the times are -.0615528128 and 4.061552813 seconds. The 2 things in math that will never EVER be negative are time and distance/length. So we know that the ball will not hit the ground at -.062 seconds. Therefore, it hits the ground 4.06 seconds after it was hit.
