Answer:
n = 5
Step-by-step explanation:
Given
[tex]\frac{n}{6}[/tex] = [tex]\frac{15}{18}[/tex] ( cross- multiply )
18n = 90 ( divide both sides by 18 )

Philip is having a party and wants to spend less than $408. He has already spent $300. The only item left on his list is sodas, which
cost $12 per case. How many cases of soda, x, can Philip purchase and stay under his budget?
Select the number line that includes the largest number of cases of soda that Philip can purchase and still stay under his budget.
ОА
Answer:
exactly 9 cases of soda
Step-by-step explanation:
408 - 300 = 108
12 x 9 = 108
so he would spend exactly 408$

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2
9. Carson draws a scale drawing of a city park and a parking lot. The city 10 points park is in the shape of aright triangle with legs that are 3 inches and 4 inches. The parking lot is in a shape of a rectangle with dimensions of 1.5 inches and 2.5 inches. The scale for the drawing is 1 inch = 40 feet. What are the TWO actual areas for the shapes that are represented?
Answer:
The answer is below
Step-by-step explanation:
The scale for the drawing is 1 inch = 40 feet.
The right angled triangle has legs of 3 inches and 4 inches. Using the scale, the length of the legs is:
3 inches = 3 inch * 40 feet / inch = 120 feet and 40 inches = 4 inch * 40 feet / inch = 160 feet.
The area of a right angled triangle is half the product of the two legs. Hence:
Area of right angled triangle = 1/2 * 120 feet * 160 feet = 9600 ft²
The rectangle with dimensions of 1.5 inches and 2.5 inches. Using the scale, the length of the sides is:
1.5 inches = 1.5 inch * 40 feet / inch = 60 feet and 2.5 inches = 2.5 inch * 40 feet / inch = 90 feet.
The area of a rectangle is the product of the two sides. Hence:
Area of rectangle = 60 feet * 90 feet = 5400 ft²
What is the slope of the line that passes through the points (1, -4) and (3, 4)?
A. 1/4
B. 5/7
C. 4
D. -1/4
9514 1404 393
Answer:
C. 4
Step-by-step explanation:
The slope formula is helpful:
m = (y2 -y1)/(x2 -x1)
m = (4 -(-4))/(3 -1) = 8/2 = 4
The slope of the line is 4.
least common denominator of 1/5 and 1/10
Step-by-step explanation:

Write a Linear Equation in
Point-Slope Form.
m = -5
(-3, – 7)
==================================
Work Shown:
m = -5 is the slope
(x1,y1) = (-3,-7) is the point the line goes through
Plug this into the point slope form below and simplify.
y - y1 = m(x - x1)
y - (-7) = -5(x - (-3))
y + 7 = -5(x + 3)
Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.
Which of the following is a decomposition reaction?
reactant plus reactant yields product
reaciant minus reactant yields product
reactant yields product plus product reactant yields product times product
Answer:
Reactant plus reactant yields product.
Step-by-step explanation:
A decomposition reaction starts from a single substance and produces more than one substance. One substance as a reactant and more than one substance as the products is the key characteristic of a decomposition reaction.

Convert the equation `5x+2y=-8`into slope-intercept form.
Answer:
y= -2.5x-4
Step-by-step explanation:
we have to isolate our y
subtract 5x from 5x+2y=-8 and move it to the right side
2y= -5x-8
divide everything by 2
y=-2.5x-4

Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.
Answer:
y = 3/5x - 17/5
Step-by-step explanation:
slope formula: (y₂ - y₁) / (x₂ - x₁)
First, plug in these values of the two given points.
(-4 - (-1)) / (-1 - 4)
Simplify within the parentheses.
(-4 + 1) / (-1 - 4)
(-3) / (-5)
3/5
This is your slope. Plug this into a standard slope-intercept equation: y = mx + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 3/5(-1) + b
Multiply.
-4 = -3/5 + b
Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.
-20/5 = -3/5 + b
-20/5 + 3/5 = b
-17/5 = b
Now, plug this into your standard equation.
y = 3/5x - 17/5
Check this equation by plugging in the other point you did not use (4, -1)
-1 = 3/5(4) - 17/5
-1 = 12/5 - 17/5
-1 = -5/5
-1 = -1
Your answer is correct!
Hope this helps!
