Morgan has an 8 1/2 foot board that must be cut into boards that are feet long. How many of the smaller boards can he get from the 8 1/2 foot board?
Which of the following equations could you use to solve the problem?
x * 8 1/2 = 5/6
8 1/2 * x = 5/6
5/6 * 8 1/2 = x
8 1/2 / 5/6 = x
Answers
Answer:
8 1/2 / 5/6 = xStep-by-step explanation:
8 1/2 foot board to be cut into 5/6 feet boards.
Number of smaller boards is:
8 1/2 ÷ 5/6 = 17/2 ÷ 5/6 = 17/2 × 6/5 = 51 / 5 = 10 (the whole part)Correct equation is D
3. Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution.

Answer:
Step-by-step explanation:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
5x + 2y = 7
6x –2y = 4
Why is this multiplication allowed? (1 point)
Because the entire equation was multiplied by the same number, the equation remains the same.
What variable will be eliminated when the equations are combined after the multiplication? (1 point)
The Y variable
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
11x = 11
Solve the equation for x. (1 point)
X = 1
What is the solution to the system of equations? (1 point)
X = 1 and Y = 1 so the answer is (1, 1)
(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

Because of demand, concert tickets that normally sell for 89.99 each are marked up 20%, If Mark wishes to purchase 8 tickets, how much will he pay in total?
20 points will be given
Answers
Answer:$863.92
Step-by-step explanation:20% of 89.99 is 18
89.99x8=719.92
18×8=144
719.92+144=
863.92
Answer:
he will pay 864 dollars in total
Step-by-step explanation:
first we have to find 20% of 90 (i just rounded 89.99 to 90).
20% = 1/5, and 1/5 in decimal form is 0.20. (you can find the decimal value by multiplying the numerator and denominator by 10/10 and then simplifying it)
0.20 * 90 is 18, so we then add that to 90 making 108.
next, since Mark is buying 8 tickets, we multiply 108 by 8, giving us 864
therefore, 864 is our final answer

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?
Answers
Answer:
A, 32
B, 48
Step-by-step explanation:
Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.
Answer:
40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save
