Equation: 120 - 4.5x = 45 + 0.5x Solution: 15
Step-by-step explanation:
So we're looking for how many days it will take for both to have the same amount of trees, the solution would be:
= 120 - 4.5x = 45 + 0.5x
= put variables to where it belongs
= 120 - 45 = 0.5x + 4.5x
= 75 = 5x
= 75 / 5x = 15
= x = 15
To confirm:
= 120 - (4.5 * 15) = 52.5
= 45 + (0.5 * 15) = 52.5

(a) Define your variables.
(b) Write a linear equation that can be used to determine the number of appetizer recipes she will learn during school
(c) Solve your linear equation to determine the number of recipes that Tara will know after 18 weeks in school
(d) Explain your answer to Part 1c.
Answers
Answer:
See below.
Step-by-step explanation:
(a)
Let w = number of weeks since she started culinary school.
Let r = number of recipes she knows at the end of week w.
(b)
Each week she learns 3 new recipes. In w weeks she learns 3w new recipes.
She already knew 4 recipes before starting school.
The equation is:
r = 3w + 4
(c)
After 18 weeks of school, w = 18.
r = 3w + 4
r = 3(18) + 4
r = 54 + 4
r = 58
(d)
After 18 weeks of school, she will know 58 recipes.
She knew 4 recipes before starting school. in 18 weeks of school she learned 18 * 3 = 54 recipes. Altogether, after 18 weeks of school, she knows 58 recipes.

Luigi and Mario are growing plants for a science fair. Luigi's plant grew 11 inches in five days. Mario measured his at one foot three inches in one week. Which student has the fastest growing plants? Show work to justify your answer.
Answers
Answer:
Luigi has the fastest growing plant
Step-by-step explanation:
Luigi and Mario are growing plants for a science fair.
Mario measured his at one foot three inches in one week.
1 foot = 12 inches
Hence, the height of Mario's plant in one week
= 12 inches + 3 inches = 15 inches
Luigi's plant grew 11 inches in five days.
7 days = 1 week
5 days = 11 Inches
7 days = x
5x = 7 × 11
x = 77/5
x = 15.4 inches
Which student has the fastest growing plants?
Luigi has the fastest growing plants
The greatest ocean depth of -35,836 feet (35,836 feet below sea level). An unmanned research submarine dives form sea level to that depth in 17 equal steps. At what depth is the submarine located after the first step?
Answers
Answer:
2,108 feets below sea level
Step-by-step explanation:
Given that:
Greatest depth = - 35,836 feets
Unmanned submarine dives to the depth in 17 equal steps
That is ; 17 equal steps was taken to reach a depth of 35,836 feets below sea level.
Depth of submarine after first step :
Depth per step :
Total depth / number of steps
35836 / 17
=2,108 feets below sea level.
Hence, Depth of submarine after first step = 2,108 feets below sea level.

y=x² - 6x + 5
(Find the vertex, show steps )
Answers
Here, a=1, b=-6 c=5
The axis of symmetry is x=-b/2a
x= -(-6)/2(1)
x=6/2
x=3
Now the y term of the axis of symmetry just means you have to plug in x=3 in to your quadratic equation for find the y term of your vertex.
y=(3)²-6(3)+5
y=9-18+5
y=-9+5
y=-3
So the vertex is (-b/2a,f(-b/2a))
So it will be (3,-3)

What is the slope of a line perpendicular to the line y=8x+1
Answers
The slope of a line perpendicular to the line y=8x+1 is -1/8.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The product of slopes of line are m₁m₂=-1
The equation of line is y=8x+1
m₁=8
We need to find m₂
8m₂=-1
m₂=-1/8
Hence, the slope of a line perpendicular to the line y=8x+1 is -1/8.

Step-by-step explanation:
Given
[tex]AB = 5\ units[/tex]
[tex]Translation = 3\ units\ rights[/tex]

Determine AB'
Length of AB' remains the same as AB
This is so because AB shifts to AB', It wasn't dilated (compressed or stretched)

The area of a rectangular wall of a barn is 12 square feet. Its length is 14 feet longer than the width. Find the length and width of the wall of the barn.
Answers
Answer:
w = 0.81 ft
l = 14.81 ft
Step-by-step explanation:
The equation of the area of a rectangle is given by:
[tex]A_{r}=l*w[/tex]
But we know that l=14+w and [tex]A_{r}=12 ft^{2}[/tex]
So we will have:
[tex]12=(14+w)*w=14w+w^{2}[/tex]
[tex]w^{2}+14w-12=0[/tex]
Solving this quadratic equation we have:
w = 0.81 ft
We just take the positive solution
So, the length will be l = 14 + 0.81 = 14.81 ft
