4. The student council sold flowers for the Sweetheart dance as a fundraising
project. They sold 200 flowers that included carnations, roses, and Gerber
daisies. The carnations sold for $1.50 each, the roses sold for $3.75 each, and
the daisies sold for $2.25. Most of the order was carnations and there were
20 fewer roses than daisies. The total flower sales came to $453.00. How
many of each type of flower were ordered and sold.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Total flowers sold = 200
Flowers are :
Carnations, Roses, and Gerber daisies
Carnations = c
Roses = r
Daisies = d
20 fewer roses than daisies ; r = d - 20
Total sales = $453
c = $1.50 each ; r = 3.75 each ; d = 2.25 each
c + d + d - 20 = 200
c + 2d = 220 - - (1)
1.50c + (d - 20)(3.75) + 2.25d = 453
1.50c + 3.75d - 75 + 2.25d = 453
1.50c + 6d = 528 - - - (2)
From (1)
c = 220 - 2d
1.5(220 - 2d) + 6d = 528
330 - 3d + 6d = 528
330 + 3d = 528
3d = 528 - 330
d = 198/3
d = 66
66 × 2.25 = $148.5
c = 220 - 2(66)
c = 88
88 * 1.50 = $132
r = d - 20
r = 66 - 20
r = 46
46 × $3.75 = $172.5

Answer:
y = -9x - 42Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
Given line:
y = 1/9x + 6Perpendicular line is:
y = - 9x + b and passes through the point (-7, 0)0 = -9*(-7) + bb = - 42So the line is:

What is the slope of the line x=5
The slope of the line x = 5 is undefined.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation that models it is given by;
y = mx + b
x = 5
This ultimately implies that, this line is a vertical line and as such, it has no slope or an undefined slope. Therefore, the x-intercept is 5 and the slope is undefined.

What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts right-hand operand from left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
To determine the product of (-10)(-10)(-10)
⇒ (-10)(-10)(-10)
Multiplying the last two terms and (-) signs cancel out each other,
⇒ (-10)(100)
Multiplying the two terms,
⇒ -1000
Hence, the value of product of (-10)(-10)(-10) is -1000.

what value of w makes the expression equal to a number less than 3?
step by step explanation
A number is equal to the sum of twice the number and negative three. Look Out: be very careful with "less than." Three less than a number is translated as "x – 3." The reverse of that, "3 – x," would be a number less than 3
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

What is rounding off numbers?Rounding off numbers is a process used to simplify or approximate a numerical value to a specific degree of precision or to a specified number of decimal places. It involves adjusting a number to a nearby value that is easier to work with or more meaningful in a particular context.
When rounding off, you typically consider a specific digit in the number and look at the digit to the right of it. Depending on the value of that digit, you either increase or keep the original digit unchanged.

How many solutions does this equation have? –10 − 9z = –4 − 10z
Answer:
1 solution
Step-by-step explanation:
-10 - 9z = -4 - 10z
Isolate z:
-9z + 10z = -4 + 10
z = 6
This is the only solution, so the equation has 1 solution.
Answer:
z = 6
1 solution
Step-by-step explanation:
–10 − 9z = –4 − 10z
Add 10z to each side
–10 − 9z+10z = –4 − 10z+10z
-10 +z = -4
Add 10 to each side
-10 +z +10 = -4+10
z = 6

PLEASE SOLVE FOR Y: [tex]7y+4=3-2y[/tex]
Answer:
[tex]y = \frac{-1}{9}[/tex]
Step-by-step explanation:
[tex]7y + 4 = 3 - 2y[/tex]
add [tex]2y[/tex] to both sides
[tex]7y + 4 + 2y = 3 -2y + 2y \\9y + 4 = 3[/tex]
add [tex]-4[/tex] to both sides
[tex]9y + 4 -4 = 3 - 4 \\9y = -1[/tex]
divide both sides by [tex]9[/tex]
[tex]\frac{9y}{9} = \frac{-1}{9} \\[/tex]
[tex]y = \frac{-1}{9}[/tex]
The solution to the equation 7y + 4 = 3 - 2y is y = -1/9.
Here, we have,
To solve for y in the equation 7y + 4 = 3 - 2y, we can follow these steps:
Step 1: Combine like terms on both sides of the equation:
7y + 2y = 3 - 4.
Simplifying:
9y = -1.
Step 2: Divide both sides of the equation by 9 to isolate the variable y:
(9y)/9 = (-1)/9.
Simplifying:
y = -1/9.
Therefore, the solution to the equation 7y + 4 = 3 - 2y is y = -1/9.

Dwayne buys 1 loaf of bread and 6 eggs for $4.45. Sheila buys 1 loaf of bread and 1 dozen eggs for $5.65. Let x be the cost, in dollars, of a loaf of bread. Let y be the cost, in dollars, of an egg.
Answer:
cost of bread = $3.25
Cost per egg = $0.2
Step-by-step explanation:
Given the following :
Cost of a loaf of bread and 6 eggs = $4.45 - - (1)
Cost of a loaf of bread and a dozen eggs ( 12 eggs) = $5.65 - - - (2)
Let x = cost of bread and y = cost of egg
x + 6y = 4.45
x + 12y = 5.65
Subtract 1 from 2
6y - 12y = 4.45 - 5.65
-6y = - 1.2
y = $0.2
Hence,
From x + 6y = $4.45
Where y = $0.2
x + 6($0.2) = $4.45
x + $1.2 = $4.45
x = $4.45 - $1.2
x = $3. 25
Hence, cost of bread = $3.25
Cost per egg = $0.2
Johnny is saving money to buy a PS 5. He already has $30 in the bank and gets $10 per week allowance for doing his chores. Write an equation to to find the number of weeks, x, it will take him to have $600.
Answer:
10x + 30 = 600
Step-by-step explanation:
Johnny gets $10 per week, which is $10x for x number of weeks.
He already has $30, so his money becomes 10x + 30.
His goal is to have $600, so our equation becomes 10x + 30 = 600

A 15-foot log is cut into two pieces. How long is each piece if the longer piece is 1.5 feet shorter than twice the shorter piece?
Given that:
A 15-foot log is cut into two pieces.
Longer piece is 1.5 feet shorter than twice the shorter piece.
Solution:
Let the length of shorter piece be x feet. So,
Length of longer piece = 2x-1.5 feet
Total length = x+(2x-1.5) feet
Now,
[tex]x+(2x-1.5)=15[/tex]
[tex]3x-1.5=15[/tex]
[tex]3x=15+1.5[/tex]
[tex]3x=16.5[/tex]
[tex]x=\dfrac{16.5}{3}[/tex]
[tex]x=5.5[/tex].
So, length of shorter piece is 5.5 feet.
[tex](2x-1.5)=2(5.5)-1.5[/tex]
[tex](2x-1.5)=11-1.5[/tex]
[tex](2x-1.5)=9.5[/tex]
So, length of longer piece is 9.5 feet.
