3 times 7 plus 4 to the second power minus 14 divided by 2
Answers
=> 3 x 7 + 4^2 - 14 / 2
Let's group this one.
=> (3 x 7) + 4^2 - (14 / 2)
=> 21 + 16 - 7
=> 30
The answer is 30.

In Andrew’s Furniture Shop, he assembles both bookcases and TV stands. Each type of furniture takes him about the same time to assemble. He figures he has time to make at most 18 pieces of furniture by this Saturday. The materials for each bookcase cost him $20.00 and the materials for each TV stand cost him $40.00. He has $600.00 to spend on materials. Andrew makes a profit of $60.00 on each bookcase and a profit of $100.00 for each TV stand. Find how many of each piece of furniture Andrew should make so that he maximizes his profit.

Answer:
They will hit 180 seconds in 118.6 year
Step-by-step explanation:
Let M be the record for the mile (in seconds)
Let x be the year after 1958
So, x=(year)-19548
We are given that In the half-century since then, the record has decreased by 0.5 seconds per year
So, slope = m = 0.5
Now we will use point slope form
y = mx+c
So, we can express M as,
Now we are supposed to find when they will hit 180 seconds
Substitute M = 180 in equation
180=239.3-0.5x
x=118.6
So, they will hit 180 seconds in 118.6 year
Final answer:
You can model the decreasing record time with the linear equation y=239.3-0.5x, where x is years since 1958 and y is the run time in seconds. By using this model, you can find the record time for any given year.
Explanation:
The subject of this question is Mathematics, specifically linear equations. The question mentions an initial record of 239.3 seconds for a run which decreases by 0.5 seconds every year. We are tasked to find the running time after a certain number of years.
Let's let x represent the number of years since 1958 and y represent the number of seconds to run the race. Based on the information provided:
- The starting time (y-intercept) in 1958 was 239.3 seconds.
- The rate of decrease (slope) is 0.5 seconds per year.
Therefore, the relationship between x and y can be expressed by the linear equation: y=239.3-0.5x
To find a certain year's running time, we substitute the number of years passed since 1958 into x in the equation above and solve for y. For example, to find the running time in 50 years after 1958 (2008), we replace x with 50: y = 239.3 - 0.5(50) = 214.3 seconds.

Let's explore possible case scenarios.
---------------------
Case A) Each person gets a rose and a daisy (2 flowers per person)
In this case, Jackie can make 2 such arrangements because she has 2 roses. We have 2 left over daisies.
---------------------
Case B) Each person gets a rose only (1 flower per person)
Only two arrangements are possible for the same reason as case A. In this situation, we have 4 left over daisies.
----------------------
Case C) Each person gets a daisy only (1 flower per person)
We have 4 arrangements possible because we have 4 daisies. The left over flowers are the 2 roses.
-----------------------
Case D) Each person gets 2 roses
Only one such arrangement is possible, so this only applies to one person really. You can say that 2/2 = 1. We have 4 left over daisies in this case.
-----------------------
Case E) Each person gets 2 daisies
Since 4/2 = 2, this means we can make 2 arrangements. There are 2 left over roses.
------------------------
Case F) Each person gets 2 daisies and 1 rose
We can see that 4/2 = 2 and 2/2 = 1, meaning that we can make at most 2 arrangements here. There are no leftovers. In contrast, the other cases do have leftovers of some kind.
------------------------
In short, you can do trial and error to see which case works to fit the conditions your teacher set. Case F is what we go for to have each flower bouquet consist of 2 daisies and 1 rose. We'll get 2 bouquets possible. Notice how cases A through E have at least one left over flower (either of one kind or both types), while case F has no leftovers.

16 + 4x = 24.
4x = 24 - 16
4x = 8
x = 8 ÷ 4
x = 2
8x = 2 × 8
8x = 16
Final answer = 16.
Final answer:
To find the value of 8x, first solve the equation 16 + 4x = 14 + 10 by isolating the term with 4x. The value of x is found to be 5. Substituting the value of x into 8x gives the answer of 40.
Explanation:
To find the value of 8x, we need to first solve the equation 16 + 4x = 14 + 10. First, we subtract 14 from both sides to isolate the term with 4x. This gives us 16 + 4x - 14 = 14 + 10 - 14. Simplifying, we have 4x + 2 = 24. Next, we subtract 2 from both sides to isolate 4x. This results in 4x = 22. Finally, we divide both sides by 4 to find the value of x, which is 5. Now, we can substitute the value of x into the expression 8x to find the answer. 8x = 8(5) = 40.
