Answers
Keith ... x hours a week
Troy ... three hours less than Keith: x - 3
Joe ... two times more than Troy: 2 * (x - 3)
The correct result would be D) 2 * (x - 3).
Answer:
The answer is D because
Step-by-step explanation:
Keith = x
And Troy exercises three hours less than Keith. Thus,
Troy = x - 3
And Joe exercises two time more than Troy. Thus,

Answer:
Solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
Step-by-step explanation:
We are given equations:
We need to solve by Elimination method.
Elimination method: Add or subtract the equations to get an equation in one variable.
Rearranging the equation 1 we get
Add eq(1) and eq(2)
So, after eliminating y we get x=-1
Now finding y by putting x in eq(1)
We get y=-2
So, solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.

b.625 - 25 | x - 1990 | = 550625−25∣x−1990∣=550
c.625 +25 | x - 1990 | = 550625+25∣x−1990∣=550
d.625 +25 | x + 1990 | = 550625+25∣x+1990∣=550
Answers
Answer: b) 625 - 25 |x - 1990| = 550
Step-by-step explanation:
According to the question,
The annual profit of a company was determined by subtracting from $625,000 the product of $25,000 and the number of years either before or after 1990.
That is, On x year the total profit is,
P(x) = 625,000 - 25,000 |x - 1990|
But again according to the question,
On x years the profit is $ 550,000
Thus, 625,000 - 25,000 |x - 1990| = 550,000
⇒ 625 - 25 |x - 1990| = 550 ( by dividing both sides by 1000)
Therefore, Option b) is correct.

The solution to this question is 39.0625.
This is because you will need to multiply the width by height. As this is in square feet it will be irrespective of which two sides we choose.
The calculation that will need to be done is the following :
6.25ft X 6.25ft which will equal 39.0625.
6.25 has three significant digits so rounding 39.0625 off to three significant digits is 39.1 square feet

LaToya has allocated a maximum of $404 to spend on her gym membership. Which number line shows the possible number of months that LaToya can be a member of the gym?
Answers
Answer:
Number line with closed circle on 1 and 8, shading in between.
Step-by-step explanation:
This is the question you are referring to.
LaToya decides to join a gym for a minimum of one month to train for a triathlon. The gym charges a beginner's fee of $100 and a monthly fee of $38. If x represents the number of months that LaToya is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time:
as 100+38x=C is our equation to determine the number of months, with $404 as a Maximum amount for her to spend, we know the beginners fee is 100 and every month(Including the first) is 38 dollars. we can understand that in 8 months, she will reach exactly 404 dollars spent on her membership.
