Answer:
To do inequalities, you just need to solve the equality and then figure out what side (higher or lower) the solution is on and put in the appropriate greater-than, less-than, greater-than-or-equal-to or less-than-or-equal-to sign.
Think about the equality for this one. What equation could we right for the average number of words per week that would put Trevor right at 50,000 after 5 weeks.
If we call the number of words per week, w, we would have
w = [an expression] (You find the expression using the number of words he has to write and how many weeks he has.)
Now think about the inequality. Trevor wants to finish in five weeks or less. So as long as he writes at least this number of words per week, he'll make it. That means we want a greater-than-or-equal to sign:
w ≥ [your expression]
Step-by-step explanation:
The inequality which describes all the solutions to the inequality is
x < 3
Given the inequality expression given as -3(4 – x) + 6 < 9 – 2x, we need to find the solution to the system of inequality as shown:
\(-3(4 -x) + 6 < 9 - 2x\)
Expand the bracket
\(-3(4 -x) + 6 < 9 - 2x\\-12+3x+6<9-2x\\3x-6<9-2x\\3x+2x<9+6\\5x<15\\x<15/5\\x<3\)
Hence the inequality which describes all the solutions to the inequality is
x < 3

Step-by-step explanation:
How far did I travel to reach my destination on each day of my three-day Trip? a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination. b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination. c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answer: 81 miles
Step-by-step explanation:
The total distance traveled on the three-day trip is: 81 miles.
How did we get the value?Denote the total distance of each day's journey by D1, D2, and D3, respectively. Then write equations based on the given identities:
a. (5/8)D1 + 15 = D1
(3/8)D1 = 15
D1 = 40 miles
So, the total distance traveled on Day 1 is 40 miles.
b. 18 + (2/5)D2 = D2
(3/5)D2 = 18
D2 = 30 miles
So, the total distance traveled on Day 2 is 30 miles.
c. (5/11)D3 + 6 = D3
(6/11)D3 = 6
D3 = 11 miles
So, the total distance traveled on Day 3 is 11 miles.
Therefore, the total distance traveled on the three-day trip is:
40 + 30 + 11 = 81 miles.

Jack is 12 years older than his sister, Amy. Amy is 2 years old. In how many years will Solomon be exactly twice as old as his sister?
TYVM!! :)
Answer:
He will be exactly twice as old as his sister in -8 years. Logically, he can't age backward, but this is the answer.
Answer: hope this helps ♡
Jack will be twice as old as his sister in -8 years.
Step-by-step explanation:
If Jack could age backwards, he would be twice as old as his sister in -8 years.
Jack = 12
Amy = 2
2*2 (Amy) = 4
12 - 8 = 4 (we got 8 by subtracting amy's age from jack's age: 12-2=8)
4 is double 2.
Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.
