I WILL MARK AS BRAINLIEST! Choose The inequality that represents the statement and then graph if on The line provided. Lacey has flown at least 120 miles.
Answers
Answer: Choice b) [tex]x \ge 120[/tex]
The graph will involve a closed filled in circle at 120, with shading to the right.
See the diagram below.
============================================
Explanation:
The phrasing "at least" means "that amount or more".
Saying "at least 120" is the same as "120 or more".
Therefore, x = 120 is the smallest x can be. That's why we go for [tex]x \ge 120[/tex] which says that either x = 120 or x > 120.
Visually, we'll plot a closed filled in circle at 120 on the number line. The shading will aim to the right to indicate all values larger than 120. The closed/filled in circle is to represent we include 120 (as opposed to an open circle where we exclude it).
Due to the fact that your teacher gave you a blank number line, the placement of 120 doesn't really matter.

Answer:

Step-by-step explanation:
3(x-5)+1=2+x
Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8

Your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip. This is 1/3 of the money needed for the trip.
Let x be the total amount needed:
A linear equation in one variable can be framed as follows:
1/3 of x = 55
x/3 = 55
x = 55x3
x = $165
Thus, the total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days
Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765
Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50

What is the step by step explanation on how to solve 8 1/2 + 3 4/5? I already know the answer is 12.3 but I just need help on the how to do the work.
Answers
To add the fractions, 1/2 + 4/5, you need a common denominator. With 2 and 5, you’d have an LCD of 10.
1/2 = 5/10
4/5 = 8/10
So 1/2 + 4/5 = 5/10 + 8/10 = 13/10
Now, 13 is bigger than 10, so 13/10 is the same as 1 and 3/10.
We’ll add that to the 11 we found back in the beginning and get 11 + 1 and 3/10 = 12 and 3/10 or 12.3.

Answers
Answer
Because velocity and speed differ each other by direction, in a 100 m sprint race the person moves in a straight path without changing its direction where as in a 400 m race. The person moves in a lap around the race track and the direction changes as he turns according to the race track.

The mayor knows the area needed for a flower garden in the park. She wants the base to be a certain length. How can she determine the necessary height to get the correct area of the flower garden? Explain.
Answers
Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
Maria would determine the height by dividing the area of the garden by the base
From the question, she has the area and the base.
Also, the garden has the shape of a parallelogram
The area of a parallelogram is the product of the base and the height.
So, when the area is divided by the base, she gets the height

Write 800 as a product of its prime factors.
Answers
Answer: 2 x 2 x 2 x 2 x 2 x 5 x 5
Explanation:
We start with the string 2 x 2 x 2 x 2 x 5 x 5
Then we tack on a "2 x" up front, or at the very left, so that we double the result. This is because the jump from 400 to 800 is "times 2".
So we go from 2 x 2 x 2 x 2 x 5 x 5 to 2 x 2 x 2 x 2 x 2 x 5 x 5
